Technical Manual  

6-10 

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.
