Safety Hints
Use As Originally Intended
When controlling DISOMAT® B/C/T , or DISONET Master, pay heed to the
instructions referring to the originally intended use, given in the respective
device manuals.
Any use other than originally intended is considered inappropriate.
General Risks
The connected DISOMAT variants, or DISONET Master, correspond to
the state of the art and are safe in operation. There may be residual risks,
if devices are used by inexperienced persons other than originally
intended.
Safety-Minded Operation
Any person being involved in EDP controlling of the DISOMAT is
required to know the respective manuals and particularly the safety
hints.
The connection of the DISOMAT or the DISONET Master to an EDP
and its control via data line may exclusively be performed by trained
and authorized personnel who is supposed to be familiar with the
weighing functions.
Error messages must be acknowledged only if cause of error has
been remedied and risks are excluded.1
Error messages may be acknowledged by password entry only if
cause of error has been remedied.1 If control systems are connected
to the subordinate DISOMAT ensure that they remain in a safe state
after acknowledgement of error.
1
Data Communication, DKI 116 e, 23.7.97
With DISOMAT® T, error messages need not be acknowledged. Messages efface
automatically once error has been remedied.

2 Safety Hints
Symbols for Residual Risks
Some commands can be used only in interactive mode. This applies in
general to all risky commands such as acknowledgement of an error
message und starting of a feeding process.
In Manual these commands are marked with the opposite symbols.
Using these commands without operator acknowledgement may cause
bodily injuries or material damage.
Ensure that for EDP control of the DISOMAT risky commands will be
executed only after operator acknowledgement. Prior to
acknowledgement the operator must ensure that all risks are excluded.
If this is impossible you should operate the EDP control system without
risky commands.
Safety Hints for the User
The user is responsible for the EDP control of the connected
DISOMAT in due form.
Responsible persons working on plant are required to know the
chapter Safety Hints and the relevant items in Operating and
Commissioning instructions.
Prior to commissioning the responsible persons are required to check
to see if EDP operation of DISOMAT or DISONET Master might
jeopardize the safety of other machines or system components. If
need be, additional safety hints have to be formulated.

3 Introduction

Introduction
If devices of the DISOMAT family are connected to and remote-controlled
from a superordinate EDP system (process computer, PC, programmable
logic controls), certain declarations on electrical connections (physical
level) and data communication are necessary.
Every DISOMAT can be integrated in a local network via serial interface.
Data communication uses Protocols. Protocols comprise a set of rules
established for connection set-up, formatting and data encoding as well as
for ensuring faultfree transmission. All protocols used with the DISOMAT
variants operate with reports for sending and receiving of data blocks
(messages) and confirmation of connection (acknowledgement).
All protocols feature the immediate response behaviour: DISOMAT
responds to each message directly and with time-delayed commands,
automatically sends an additional message reporting due execution (e.g.
taring expects standstill).
Data to be transmitted, the socalled user data, are packed in data
messages which additionally include control and block check characters.
The control characters determine the beginning and end of the data
message. To that end, user data are limited either by a start- or end-oftext character, or a message header determines the total length of data
message1.
Permitting the receiver to recognize error in data transmission, the block
check characters (BCC) serve for data protection.
Data and user data as such can be character-encoded (e.g. 7-bit ASCII,
8-bit ASCII) or transmitted as binary bit strings.

Description:
Scale with scale number WN is to tare remote-controlled by EDP. EDP
transmits taring command (2#AT#) to DISOMAT (1). However, taring
requires certain marginal conditions to be met, e.g. DISOMAT must have
recognized No-motion. This may take some seconds. Therefore DISOMAT
immediately outputs an immediate response message informing EDP that
command is being processed (2). DISOMAT tries to tare scale and, once
command is duly executed, transmits a response message including user
data WN#AT#0#. If execution fails, response includes a figure
unequal to 0, e.g. WN#AT#1#, if DISOMAT has not identified no-motion
after a certain period of time.

4.2 SCHENCK Poll Protocol
SCHENCK Poll Protocol1
This protocol has been developed from the SCHENCK Standard Protocol
(see Item 4.1, or Spec Sheet DDP 8 672) and is used for special
applications, for instance, running weight display in superordinate PC.
EDP starts communication direct with request message and DISOMAT
responds with corresponding data record. This is done without
acknowledgement and without repeat in case of error. Transmission of
data contents is secured through block check mechanism (recognition of
faulty messages).
With this protocol, important response messages can get
lost, particularly the delayed response messages whose
output time is not exactly predictable.
Note:
Examples:
The feed result message (DO) may be output several hours after start
of feeding.
The delayed message of taring command (AT) follows direct after first
reaction only if scale is in no-motion.

Value Range
The value range of transmitted characters of a data section covers 8 bit,
i.e. in hexadecimal representation 00 to FF.
This value range requires a special treatment of user datas’ end code
(<DLE>), if the bit string of the <DLE> character is included in user data.
This is done by doubling the <DLE> character.
<DLE> Doubling:
A <DLE> ocurring in user data is doubled by transmitter, for receiver to
completely receive user data.
If two <DLE> codes are received, receiver resets doubling and treats
<DLE> as data byte.

EDP transmits command for weight value transmission at no-motion (1)
and receives immediate response that command has been understood.
Then, DISOMAT sends delayed message. If command can be executed
within preset period of time (20 seconds), delayed message includes
requested data, here: weight values (3). If not, corresponding error
message is output after elapse of preset period of time.
(Command s in response message stands for EDP command status.)
Note:
With "Transmit Data" the immediate response is also sent.
The second response message is omitted.
For further samples, see Items 4.1 and 4.2.

SIMATIC S5 Control
The protocol used with SIMATIC S5 differs from the SIEMENS 3964R
protocol by the 10-byte message header ahead of user data which
comprises address, command and length information.
To address a scale,
Data block (DB) has to be used for a scale number (0...255) and
Data word (DW) has to include the message code.
Corresponding values are listed in the Table shown at Chapter 6.
Messages to DISOMAT are routed to directly adjacent addresses.
Example: "Weight At No-motion Request" to DW=6, "Periodic Request"
to DW=7.
Address of AD Messages routed from DISOMAT consists of a data
block entered in dialog and the data word (fixed value) for message
identification. (See Chap. 6.1, Page 37.)
In SIMATIC S5 Mode, all data are transmitted in ASCII code.
Data block or word are represented hexadecimally 0..FF.

Acknowledgement
Receiver acknowledges successful data transmission with <DLE>; faulty

Value Range
The value range of transmitted characters of a data section covers 8 bit,
i.e. in hexadecimal representation 00 to FF.
This value range requires a special treatment of user datas’ end code
(<DLE>), if the bit string of the <DLE> character is included in user data.
This is done by doubling the <DLE> character.
<DLE> Doubling:
A <DLE> ocurring in user data is doubled by transmitter, for receiver to
completely receive user data.
If two <DLE> codes are received, receiver resets doubling and treats
<DLE> as data byte.
4.4.2 Sequence
Description of AD and ED Messages:
AD messages (SEND messages) consist of message header (10 bytes)
followed by data. Response message contains 4 bytes.
ED messages (FETCH messages) consist of message header (10 bytes).
Response message comprises messages header cut down to 4 bytes
followed by requested data.

4.6 J-Bus (Modbus)
J-Bus (Modbus)
The J-Bus, or Modbus introduced by Gould Modicon1, is a bus system
primarily used in France. It is mainly used for control of peripherals
through programmable logic controls (PLC). The two bus systems differ by
their physical connections.
While Modbus exclusively admits RS485 4-core interfaces, J-Bus is
specified as RS485 2-core and, designed as point-to-point connection,
also admits current interfaces and RS232.
DISOMAT® C supports Modbus.
DISOMAT® B supports J-Bus ans is capable of using the protocol on a
point-to-point connection.
In principle, the DISOMAT variants do use RTU framing.
J-Bus and Modbus are real bus systems, i.e. all devices are connected to
bus in parallel and a bus master controls the access to bus ("MasterSlave Principle").
Of the numerous functions the J-Bus protocol provides, suffice three to
realize the required functionality:
1. Type 3: Read multiple words
For data requests;
corresponds to SIMATIC S5 ED messages
Example: Request Weight
2. Type 6: Write one word
For commands with no data;
corresponds to SIMATIC S5 AD messages
Examples: Tare or Start Feeding
3. Type 16: Write multiple words
For commands with data;
also corresponds to SIMATIC S5 AD messages
Examples: Preset Setpoint, Key-in Tare
For message construction, see Item 7.4.

Calibration Group:
In addition to the above messages, all initiated by EDP, there is a number of messages initiated by DISOMAT.
Note:
This does not apply to J-bus mode. In SIMATIC S5 mode, these messages are sent only if the address data block entered in
the DISOMAT dialog is not equal to zero. Messages are then sent to data words in this address DB with fixed offset.

Immediately after having read a set EDP input contact DISOMAT will
automatically reset it. Therefore direct connection of the EDP input
contacts to an output contact is useless, as physically only a short pulse
will occur at the output.

Function Blocks
The table below shows all function blocks of DISOMAT® B and
DISOMAT® C.
Following commands require identification of the function blocks and their
outputs:
EV and AV for linking the function blocks (EV = Acquire function block,
AV = Read function block)
EP and AP for parameterization of the function blocks (EP = Acquire
function block parameter, AP = Read function block parameter).
For changing the function block configuration, observe the following
sequence of commands to be executed:
1. EV + EP
Commands for input of linkages and parameters
2. SV

Scale Number
5e
Message structure: For scale - 4 floating point numbers in Teleperm M
format with the following meaning:
Number 1 :
Number 2 and
number 3 :
Net of scale in kg (fixed).
Values of the DISOMAT® C analog EDP
outputs. Via function block linking these outputs
can be assigned e.g. to Gross, dW/dt, Balance,
...
Value range of these outputs is -1...+1. During ouput
this range will be standardized to full scale value, i.e.
the output values are between -full scale value and
+full scale value.
Thus, GROSS output will be in kg.
If Max_dW/dt and Max_Balance are appropriately
selected, value can be output in useful units.
Number 4:
Error number on scale (without error class
specification). For meaning of the individual error
numbers see DISOMAT® C Operating and
Commissioning Manuals.
For sample computation, Item 8.2.

No periodic output
Error on interface. Periodic output must be
reinitialized.
Wrong switching values of comparators.
Wrong values transmitted. The values must be
transmitted in % of full scale value.
Changing over from fill feed to discharge
feed (command code 145 and 146) of
flexible command message does not
work.
No function block configuration. The change-over
command is executed only in the input range (Start/Stop). Complete configuration with all necessary
function blocks is required.
Feed process aborts after Stop.
Stop command message has been transmitted twice.
(2x Stop=abort)

7.4 J-Bus/Modbus-Procedure
J-Bus/Modbus Protocol
General Information on J-Bus (Modbus)
In the RTU version realized for DISOMAT all messages have the following
construction:
Slave Address (1 byte)
Function Code (1 byte) < 127 data
Block check (2 bytes)
DISOMAT accepts only messages with Slave address corresponding to
the scale number entered via dialog (menu item EDP configuration).
The data construction depends on the function code used (for detailed
description of function codes, see page 79ff).
The block check will be computed as Standard CRC16.
End of message will be recognized after expiry of 25 msec without
receiving any characters. As a rule, the J-Bus (Modbus) specifies the time
of 3.5 characters, i.e. 25 msec at 1200 baud. At higher speeds, DISOMAT
delay time is too long, however, without any adverse effects on protocol.
Note:
Speeds < 1200 baud are not permitted.
The J-Bus (Modbus) operates according to a strict Master-Slave Protocol,
i.e. a Slave can only respond to a message from Master. Active
transmission is not allowed.
According to the J-Bus-Protocol (Modbus-Protocol), a response is
provided for each message from Master.
Response message is constructed as under:
Slave Address (1 byte)
Function Code (1 byte)
Data
Block Check (2 bytes)
If job is duly processed, function code is identical to that in the message
from Master. In case of error, the 8th bit will be additionally set and data
contain an error code.
Data construction depends on function code used.

7 Protocol-Specific Features
7.4 J-Bus/Modbus-Procedure
Special Features of the J-Bus/Modbus
The J-Bus Protocol is a true Master-Slave Protocol, i.e. data enquiry is
executed only from Master to Slave. No Slave can transmit data without
request from Master. As a consequence, delayed reponse message do
not arrive, i.e. all EDP functions implying a delayed reponse message are
not applicable or to be limited extent only (delayed response on
success/failure is missing).
These are:
EDP Functions Not Applicable
for J-Bus/Modbus
Correction / Solution
Acquire tare
Look for tared bit in scale status.
Zeroing
Look for weight near zero.
Weight enquiry at no-motion
Determine weight without nomotion and look for no-motion bit.
Periodic weight enquiry
Read weight periodically.
Message Feed stopped
Read feed status periodically.
Actual value message after
completion of feed process
On completion of feed process
store weight value in a memory
linked with a analog EDP output
(connection of function blocks),
look in feed status for feed end
and read then analog output (see
definition of command TK "Read
all contacts")
The data will be transmitted in ASCII Code, i.e. the ASCII messages
will be used, however, without #XX# command code, thus ensuring their
universal application for all the various machine-dependent data formats
during J-Bus transmission (Modbus transmission).

Special Features of DISONET
Master
DISONET Master is able to execute the following EDP protocols:
DDP 8 672 Standard Protocol
3964R
SIMATIC S5
Teleperm M
(see table at Item 3.1, page 6)
Available are all functions provided by one DISOMAT in these modes of
operation, though due to the routing of messages via DISONET the
response time will be prolonged depending on the number of slaves.
Max. number of slaves is 8, mixed operation with DISOMAT® B, C, D
and T as slaves is possible.
If it is useful, DISONET Master itself can proceed a subset of EDP
commands concerning e.g.
Error enquiry and acknowledgement
Device identification
Note:
Data Communication, DKI 116 e, 23.7.97
Special features of DISONET Master with SIMATIC S5
Protocol:
The address of DISONET Master in the 5th byte of the
message head shall not be 0, as SIMATIC S5 does not
accept input of 0.
Remedy: Assign to the DISONET Master an address
which is unequal 0 and does not coincide with a
slave number of the connected DISOMAT.
Enter this address in the routing table of the
DISONET Master (see Manual DKI 117) and
use it in the message head of SIMATIC S5.

Data word:
Number Output (AD)
will be transmitted via start message
Message structure: For each connected scale 4 floating point numbers in
Teleperm M format with the following meaning:
Number 1 :
Net weight of load on scale in kg (fixed)
Number 2 and
number 3 :
Values of the analog EDP outputs of the
respective DISOMAT. Via function block linkage
these outputs can be assigned to Gross, dW/dt,
Balance,...
Value range of these outputs is -1...+1. During output
this range will be standardized to the full scale value,
i.e. the output values are between -full scale value
and +full scale value.
Thus, GROSS output will be in kg.
If Max_dW/dt and Max_Balance are selected
accordingly, values can also be output in useful units.
Number 4: Error number on scale (without indication of Error
Class). For meaning of the individual error numbers,
see DISOMAT® B, C or T

8.2 Teleperm M Protocol with DISONET®-Master
8 Special Features of DISONET Master
Examples for computation of number 2, or 3:
The actual value of the parameter linked with the EDP output shall be
transmitted to EDP for further processing.
The transmitted numerical value at output NumberOutput is related to the
full scale value, as in most cases weight values are required.
Computation formula (numerical value equation):
NumberOutput
Actual Value
Max. Value
Full Scale Value
In case of weight value transmission the max. value equals the full scale
value, i.e. NumberOutput indicates the weight value direct.
With a GROSS weight of 250.1 kg, at the EDP output the numerical value
250.1 will occur on condition that the GROSS weight is linked with the
EDP output. This numerical value can be processed immediately.
If no weight values are linked with the EDP output (e.g. Balance or dW/dt)
there are two possibilities: Either suitable presetting of the max. value in
the DISOMAT or recomputation of the numerical value NumberOutput to the
required actual value via EDP according to the following formula:
NumberActual Value
NumberOutput
Max. Value
Full Scale Value
Example:
Full scale value = 3000 kg
Max dW/dt = 50 kg/s
dW/dt = 7.5 kg/s
NumberOutput
7.5
50
3000

This numerical value must be recomputed via EDP to obtain the actual

For communication of DISONET Master with central data processing
system (PC or PLC) a flexible message type has been defined.(#FL# for

It is characterized in that several command codes with their parameters
can be transmitted via one single message.

and start signal in one message:
MA#FL#01#32#125.00#143#2#5#1#300#20#0.8#1.0#0#36#0#
The most decisive advantage of this message is the time saving, as with
other message types a number of individual messages is required to
transmit the data to the respective DISOMAT.
Not all defined commands are useful for such a message. Therefore we
have made a selection specified in a list of FL command codes (see table
below).
For faults, the following protocol has been defined:
If there is an error in the execution of specific commands (see foot note),
the consecutive number of this command in message command will be
transmitted to EDP and the subsequent message commands are no
longer executed.
The users's EDP must consider this for system control. DISONET Master
cannot make any corrections.
Parametrization commands 140-144 are followed by function block
meaning (command ´EP´)
A WN#FS# command= Start function blocks must then be sent .

Limitations
In spite of the enormous capability of the remote control EDP interfaces,
some settings of DISOMAT® B or DISOMAT® C can be parametrized only
in the dialog mode.
This applies to the following DISOMAT interface settings:
Parameter definitions for the serial interfaces SS1 and SS2
DISONET network settings
EDP configuration
Printer configuration
Analog output setting
BCD output parametrization
Secondary display parametrization
As a rule, the DISOMAT interfaces cannot be set via EDP. This might
lead to parametrization errors which the user EDP itself cannot detect nor
reset.
Furthermore:
Display test
Display contrast setting
Print repeat
Start of parameter printing
Selection of a fixed tare value
These functions are useful only in combination with the device itself.
Therefore, they are not implemented as EDP commands.
