G4 Multi Channel Force Instrument

Modbus protocol 

For communication with a master computer (PLC) the Modbus protocol is used in  
the instrument. The Modbus protocol is a standard protocol, used for master/slave 
communication in the industry. 

Information is transmitted in blocks of data to minimise polling and response time 
delays. For example the error register, status register and sum register could be read 
with one command to the instrument.  

When a command that cannot be performed is sent, the instrument responds with  
an exception code. For a better explanation of the error, a special command error 
register could be read.  

Depending on the type of the communicating equipment (the master), the commands in 
the application programme (PLC programme, or pc programme) may be different from 
type to type. However, if the master is not a Modicon PLC system, then the Modbus 
implementation in the master must have some cross-reference function to transfer the 
Modbus register and I/O bit numbering to the masters own register and  
I/O bit numbering. All registers and coils described in this manual use the standard 
Modbus (Modicon) register and I/O numbering.  
See the master's own Modbus driver documentation for how the commands should be 
activated in the master's application programme. 

Most manufacturers of PLC systems and HMI and SCADA software can provide 
Modbus drivers. Various Modbus drivers for development of Windows programs are 
also available on the market.  

More information about Modbus protocol can be found at ‘www.modbus-ida.com’ and 
many other places.
