Vijeo Citect MODBUS RTU Communication


Thread Starter


Hi all,

I am facing a problem with a communication between Vijeo citect and a Modbus Device (Preset ACCULOAD).

I configured my Vijeo citect project normally, but the communication is off. The state of the variables is not displayed and the IOserver diagnostic shows that there are some errors.

I tested my communication with a modbus scanner and it worked well. I tried with an other SCADA software (Control Maestro) and it did work well also. So I presume that the problem is with the configuration of Vijeo Citect.

Please can someone help me with this matter.

I read that there could be some parameters that I have to set in the citect.ini file!
