Please, I would like to ask if we can eliminate OPC servers in both sides (PLC side & DCS Side). Currently, we have not trust networks between ACN & PCN. we are using OPC method to establish the communication between DCS & PLC. my question here is can we use PK controller instated of OPC. can we browse the data from PLC (Siemens) by using IP address. on other word PK controller has got two connections one with PCN and the other one with ACN. then PK controller fetch the data from Siemens PLC and then write it to ACN and versa vise. can this be done or no?
your quick response is highly appreciated.
