OPC Connectivity of Package Vendors with ICSS


Thread Starter


I have a scenario where 5 different PLCs supplied by different Package Vendors are to be connected to the Integrated Control and Safety System (ICSS) network. I have following queries:

1) If I ask for OPC connectivity from all PLC Vendors and take OPC Server from ICSS, what important information shall I convey to Package PLC Vendor and DCS Vendor?

2) How do I transfer Time Stamps for DCS-Synchronized Simplex PLC's which are serially connected to DCS Communication servers. The intent is to provide time stamps to Sequence of Event (SOE) servers.

3) If vendor does not provide HART Pass through capability, and I want to take HART MUX from DCS Vendor, what important points of contention crop up?

Each HART multiplexer vendor may use a different proprietary protocol over RS485. It may be a challenge to interface that into your intelligent device management (IDM) software

Ideally they should use HART multiplexers supporting HART-IP, but there aren't that many out there yet.

WirelessHART gateways is better, they are newer and more modern, all support HART-IP so much easier to integrate a mix of those.
