Hello All
And Happy New Year.
I am currently looking at a project that involves integration of three pieces of manufacturers plant.
There is to be one Siemens System and Two Rockwell systems.
The Siemens Architecture shows an interface to the rest of the plant via an OPC server. Straight away this makes me nervous because;
1. Different PLC systems
2. Relaibility of OPC for critical process control and interlocks.
Anyone with any experience of this? The OPC is useful as there is there is the possibility that the three system swill have to be combined on one MASTER SCADA interface.
However for anything critical my thought is to use an industrial strength network, such as Profibus. My thought is to have Prosoft Cards in the rockwells connected to a DP/DP coupler with the Siemens system as the other network. This gives a clean path for interplc comms.
Any thoughts and advice would be appreciated.
