The 87TS50 module serves as a crucial interface for connecting MMI (Man-Machine Interface) systems, such as the Plant Management System (PMS), to a PROCONTROL system. Here’s a detailed breakdown of its application and features:

Application

• Purpose:
  • The 87TS50 module is used to facilitate communication between an MMI system and a PROCONTROL system.
  • On the computer side, this communication is managed by the CPS (Common PROCONTROL Data Server) software package.
  • On the PROCONTROL side, the 87TS50 module handles the communication.
• Communication:
  • The CPS software controls the 87TS50 module and conditions the signals for the MMI system.
  • The 87TS50 module connects via a thin-wire Ethernet interface according to IEEE 802.3 standards.
  • Up to four 87TS50 modules can be connected to a single CPS interface.
  • These modules can be spread across different PROCONTROL systems with varying system addresses.
• Redundancy:
  • The module supports two modes of operation:
    • Redundant Mode: In this mode, the module suppresses the sending of send-location and destination telegrams to the PROCONTROL bus, as well as the listen-in data to the CPS.
    • Partial-Redundant Mode: Similar to the redundant mode, but only suppresses the send-location and destination telegrams to the PROCONTROL bus.
  • The CPS can set or reset a diagnostic message indicating a “Bus coupling fault,” allowing for redundancy changeover due to a disturbed CPS computer.

Features

• Integration:
  • The 87TS50 can be plugged into any station within the PROCONTROL bus system.
  • It uses a standard interface with the PROCONTROL station bus.
• Error Checking:
  • The module checks the received telegrams for error-free transmission based on parity bits.
• Ethernet Interface:
  • Through its Ethernet interface, the module communicates using the TCP/IP protocol to or from the CPS.
