SIMATIC PCS 7/90 OS Software

The SIMATIC PCS 7/90 OS software is used for the OS connection of Bailey controllers (PCUs) using an engineering system (SIMATIC PCS 7/90 ES), as well as for operation and monitoring of the PCUs (Process Control Units) using an operator system (SIMATIC PCS 7/90 OS) based on SIMATIC PCS 7.

It contains the following components:

• RoviSys OPC server, configured with DBA
• Library with block icons, faceplates and diagnostics displays, for reading and writing the available Bailey function block information

ES/OS communication with the Bailey controllers is carried out via OPC (OLE for Process Control). The SIMATIC PCS 7/90 OS software supports hardware communication via RS 232 or SCSI.

Multi-client and dual-channel functionality

Data from different systems can be displayed on the OS clients in a process picture:

• Data from Bailey controllers (PCUs) on the Bailey Plant Loop/INFINET
• Data from the SIMATIC PCS 7 automation systems on the SIMATIC PCS 7 plant bus Industrial Ethernet.

The multi-client architecture of the operator systems enables a client to retrieve data from different servers.

With smaller systems it is also possible to use a SIMATIC PCS 7/90 OS server with dual-channel functionality. This implements the communication with the Bailey controllers and the SIMATIC PCS 7 automation systems via two separate channels DLLs.
