Description
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.
Applications
Power plants: Process control for thermal power generation, hydropower generation, and nuclear power plants.
Petrochemical plants: Automation of production lines in oil refineries and chemical processing plants.
Pulp and paper mills: Distributed control of paper machines and pulping processes.
Mining and metallurgical plants: Monitoring of ore processing and metal smelting systems.
FEATURES
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.
REPLACEMENT
Turn off cabinet power if possible; disconnect +24 VDC and I/O common from E2 and E3, and mark cables.
Disconnect the serial extension cable from P3 if present.
Remove RS-232-C/RS-485 cables from DB connectors and label them.
Ensure the control module is removed from the MMU backplane connection.
Disconnect cables from P1 and P2, marking each.
Remove mounting screws and grounding screw (E1), then take out the unit.
Check jumper settings match the faulty unit.
Ensure the fuse is installed.
Insert and position the replacement unit on the panel.
Secure it with mounting and grounding screws (use star washer).
Reconnect cables to P1 and P2.
Reconnect RS-232-C/RS-485 cables.
Reconnect the serial extension cable to P3.
Reconnect +24 VDC and common wiring to E2 and E3.
Reinsert the control module fully into the MMU slot.
Restore power to connected equipment.
Restore cabinet power if it was off.
FAQ
Q: Which processors does the NTMP01 primarily connect to?
A: It is primarily used to connect multifunction processor modules such as IMMFP01, IMMFP02, and IMMFP03.
Q: Can NTMP01 support long-distance communication?
A: The RS-232 port is suitable for short-distance connections. For longer distances or network communication, one of the ports can be configured as RS-485.
Q: What special precautions should be taken when repairing this NTMP01?
A: Wiring must be performed with the power off, and the environment must be free of corrosive gases before operation to protect the circuit board solder joints.
Q: Can NTMP01 replace the NTMF01?
A: Although both are Infi 90 terminal units, the NTMP01 focuses on interface with multifunction processors, while the NTMF01 is typically used for terminating multifunction controllers. The specific system topology needs to be checked.
