Description

The NTMF01 Multi-Function Controller Termination Unit (TMF) terminates two RS-232-C ports for the IMMFC03 Multi-Function Controller, INICT01 INFI-NET to Computer Transfer Module, INPPT01 Plant Loop to Plant Loop Transfer Module and INPCT01 Plant Loop to Computer Transfer Module. When terminating an IMMFC03 module (or redundant IMMFC03 modules), it enables the IMMFC03 module to communicate to a computer, terminal, printer or sequential events recorder through the serial ports.

Applications

Large power plants: Serves as the processor terminal for boiler control or turbine coordination systems.

Oil and chemical plants: Used as a debugging interface or MODBUS protocol converter for connecting the main controller.

Paper and metallurgical plants: Responsible for external communication with the main control station in complex production line automation.

FEATURES

The multi-function controller termination unit (TMF) provides a place to connect two RS-232-C cables with DB-25 connectors. Dipshunts allow either port of the termination unit to be configured to operate as DTE or DCE devices. This feature allows the termination unit to terminate a number of computers or terminals. One serial link connection on the termination unit enables a multi-function controller module to communicate to an NDCS03 Digital Control Station or IISAC01 Analog Control Station.

Mounting

To mount the termination unit:

1. Insert the tabs of the circuit board into the proper slots of the termination panel standoff slide the circuit board into position.

2. Secure the termination unit circuit board to the field termination panel with two number ten self-tapping screws .

3. Connect the chassis ground by installing a number ten self-tapping screw and external star washer in the location (E1).

FAQ

Q1: Who is the NTMF01 primarily used for?
A: It is specifically designed for use with ABB multifunction processors (such as IMMFP11/12), and is an essential accessory for external communication and I/O of the processor.

Q2: Can I use the serial port on the NTMF01 to download programs?
A: Yes. Its RS-232 interface is typically used to connect to a configuration workstation for logic downloading or online debugging.

Q3: Why can't I communicate even after connecting the serial port about NTMF01?
A: Please check if the baud rate jumper setting on the NTMF01 is consistent with the host computer software, and confirm the wiring sequence of the communication cable.

Q4: Does NTMF01 support redundant configuration?
A: The terminal unit itself is usually not redundant, but the processor module it connects to can be configured as a redundant pair.

Q5: Will the control system shut down if the NTMF01 is damaged?
A: If the damage affects the logic feedback of the main processor or causes a communication deadlock, it may cause the control loop to switch to a safe state or shut down.
