NTMP01 Multi-Function Processor Termination Unit

Product Description

Termination units provide a connection from the plant equipment to the INFI 90® process modules. The NTMP01 Multi-Function Processor Termination Unit terminates a multi-function processor, INFI-NET® to computer transfer module, INFI-NET to INFI-NET transfer module or multi-function processor interface module. The NTMP01 Multi-Function Processor Termination Unit provides a termination point for two RS-232-C ports or one RS-232-C port and one RS-485 port, plus a serial link to connect an analog control station or digital control station through an NTCS04 Control I/O Termination Unit. This product instruction explains how to install and use the NTMP01 Multi-Function Processor Termination Unit.

The NTMP01 Multi-Function Processor Termination Unit provides a connection to the serial interface for IMMFP01, IMMFP02 and IMMFP031 Multi-Function Processors. It has two isolated RS-232-C ports (one of which can be configured as a nonisolated RS-485 port) to operate as either data communication equipment (DCE) or data terminal equipment (DTE). Multi-function processors (MFP) use these ports to communicate with field devices (e.g., computers, printers and sequential events recorders). The multi-function processor termination unit (TMP) also provides the connection for a station serial communication link. This communication link allows the MFP module to communicate with an IISAC01 Analog Control Station or NDCS03 Digital Control Station. Figure 1-1 shows a typical TMP termination unit application.
The termination unit also interfaces with the INIIT02 INFI-NET to INFI-NET Transfer Module. The INFI-NET to INFI-NET transfer module (IIT) supports bidirectional communication through two RS-232-C ports. Port one passes system data only. Port two passes system data or can be used as a diagnostic port.
The central IIT module can use a variety of means to link to the satellite IIT module such as modems, microwave and transceivers.
The termination unit also interfaces with the INICT03 INFI-NET to Computer Transfer Module2. The INFI-NET to computer transfer module (ICT) provides the electronics needed to direct the operation of the INFI-NET to computer interface. It handles all communication with the host computer through the multi-function processor interface (MPI).

Product parameter

Application field

The TMP termination unit has two jumper configurable RS-232-C ports for DCE, DTE, nonhandshake or loopback operation. These ports allow the MFP module to communicate with computers and terminals. The termination unit also provides two serial communication links for analog control stations (SAC) and digital control stations (DCS) through the NTCS04 Control Station Termination Unit. When both ports are configured as RS-232-C ports, the TMP termination unit provides isolation between INFI 90 and the connected equipment (the RS-485 port is not isolated).
The TMP termination unit has two LEDs. The LEDs identify which MFP module (primary or redundant) is the active module. This indication is useful for troubleshooting and maintenance.
