CI867 Data Exchange
I have configured CI867 as master and through modbus tcp slave i am getting the datas from flow computer, in the mean time i need to transfer some variables from our DCS to the same flow computer. Is it possible and please suggest me on this.

Hi, Yes it is possible first read and then Write data to flow computer.You can not do both read&write simultaneously. Create a function block as Modbus Write to write data to flow computer.
Use Function Code 05, 06, 15 or 16 to write coils/registers to slave from master.
