Citect to Delta PLC via TCP

Those PLC's can talk Modbus RTU, use the Citect 'Modbus' driver. The Driver Reference Help can guide you on how it is setup to talk to your device.

Thanks Richard
I have solved it since I posted.
Use the Comms Manager configured on Ethernet to find the plc and check that IP is correct.
Use Modnet protocol driver in Citect and Modbus address+1 as specified for delta PLC's.

Hi Gary,

I would never use address+1 for variables, it's confusing. Better use "MODNET1" protocol variant instead. Look in the driver help for additional protocol variants and parameters.

Hi Patrick
Thanks for your reply, I also find it confusing. I will try "MODNET1".

Regards Gary

Hi Patrick
MODNET1 works without having to add 1 to address.
Thanks a million !

No worries, I missed the TCP part :), modnet is the one
