87TS50 ABB Coupling Module

Description:

The 87TS50 module is a coupling module for connecting MM!systems, such as the Plant Management System 'PMS', to a PROCONTROL system.
Communication between the MMl system and the PROCONTROL system takes place, on the computer side.with the help of the CPS software package(Common PROCONTROL Data Server),and on the PROCONTROLside, through the 87TS50 module.
The CPS controls the 87TS50 and conditions the signals for the MMl system.
The 87TS50 is connected via a thin-wire Ethernet interface acc. to IEEE 802.3.
A total of four 87TS50 modules can be connected to one CPS interface. The module's scope of action extends over the entire PROCONTROL system where it is being used.
It is possible to plug a maximum of four 87TS50 modules linked to one and the same CPS interface into different PROCONTROL systems,i.e.into systems using different system addresses (cf. 'Conneclion diagram').

The module is also suitable for redundant-station arrangements. lt may be operated in two modes:
-Redundant mode
-Partial-redundant mode
Module application in redundant stations as described below:
"Redundant' mode
When used in the passive REDUNDANCY, the sending of send-location telegrams and destination telegrams to the PROCONTROL bus and of the listen-in data to the CPS is being suppressed.
'Partial-redundant' mode
When used in the passive REDUNDANCY, the sending ofsend-location telegrams and destination telegrams to thePROCONTROL bus is being suppressed.
The CPS can set or reset diagnosis message 'Bus couplingfault'. Therefore, a redundancy changeover may be effected due to a disturbed CPS computer.
