Operator Eco structure Operator Terminal Expert HMIST6700 simultaneous connection with Schneider PLC over modbus ethernet

[paithankar100]

Hi,

I have HMIST6700 HMI. I need to show and control data from 4 different PLCs over modbus Ethernet. Is it possible using different symbol links in operator terminal expert. What is the maximum limit a single HMI6700 can communicate with different PLCs over modbus ethernet protocol?

Thanks

Hi

Yes you can use diferent symbol-links in EOTE.

If the HMI act as Slave then the max. connection is 20 and if the HMI act as Master the max. connection is 64.

Greetings
