Hi,

It is Possible as long as Maximum 3 OPC DA/AE subscribers per controller can be maintained.If redundant connectivity servers are used then no. You might have to look at option of using OPC surrogate server to read data from one CHMI to another using Generic OPC Client or PLC Connect connectivity.
