Control System Components 1

Standards defined by Controls Board, JCOP, IT/CO Supervision: PVSS SCADA Toolkit Programmable Logic Controllers (PLCs):

Siemens and Schneider (with UNICOS PLC library) Field Buses

CAN Bus, ProfiBus, WorldFIP, (and possibly Ethernet) OLE for Process Control (OPC)

Interface for Commercial H/W available on Windows Distributed Information Manager (DIM)

Interim solution for non-commercial H/W Information/Support for a variety of equipment:

Wago, Wiener, Applicom, SoftPLCs, N.I., Beckhoff, etc.
