Hi all,

Please help me to have a communication of dedicated controller working with MODBUS and Citect scada,I want to do it on COM Port-1.
I have defined Board and Port for Citect scada but it is not communicating is there ary another procidure for the same?
 
I have set these up a few times, and whenever I followed the citect help files exactly, it always worked. Some things to check:
Are you using modbus rtu or ascii?
Baud rate?
Data and stop bits?
Also, what PLC are you using?
