Put 4 CNR blocks into your REX algorithm and then write to e.g. "yourtask.CNR:ycn" from the OPC client software.

Fetching data from another DCS system through OPC

Hi,

I am unable to understand how to write data into a Rex function block from another DCS system.

I had gone through the REX OPC manual. I am able to see all the REX function blocks and the real time values of my code using COGENT data hub OPC client software.

I need to write 4 analog values from the Metso DCS system into REX for further processing by REX. Can somebody guide me with any example of how to fetch data from a third party PLC or DCS system into REX through OPC.

Thanks !
