Dear All,
I found a problem when i try to commnunicate Citect Scada with AB PLC 1800 over Modbus TCP/IP. AB PLC act as Modbus Master and Citect as Modbus Slave. I am using MBSlave TCP on Citect, my configuration is according Citect's KnowledgeBase Q2015.But I Still can't communicate. And why can't I find MBSlave Parameter on Citect.ini?
Thank's

 

You should probably look at MODNET rather than MBSlave. MBSlave was only meant for serial comm's. Modnet is for TCP/IP.

As far as ssetting up citect.ini protocol parameters, you must create the section header yourself
[MODNET]

to know what parameters to use for each driver, go to help>driver Help>[driver name]>Parameters

(suggest you also try using the CiConfig utility makes it easier to edit the citect.ini)

Hello, I'm not sure if it is possible to use the Standard Modnet Driver as Slave Driver.

Kind Regards

There is an MNSlave Driver available which is just that, Modnet Slave, but you will need to contact Citect Support to get this one.
