More Information

Overview Manuals Specifications Serial Ports Controller Interface Cnet Transfer

Features:

  • Two isolated RS-232-C ports
  • One non-isolated RS-485 port
  • Cnet-to-Cnet communication interface
NTMP01 provides the serial and Cnet termination functions associated with ABB rack-mounted Harmony controllers.

Its port architecture separates two isolated RS-232-C paths from one non-isolated RS-485 path, giving NTMP01 distinct grounding and interface considerations.

For transfer-module applications, NTMP01 must also carry the correct DTE or DCE jumper state and installed cable configuration.

Availability for NTMP01 is subject to Apter Power's current inventory and sourcing confirmation.

Description
ABB NTMP01 is a multi-function processor termination unit used with rack-mounted Harmony controllers. It brings the controller’s serial communication and Cnet-to-Cnet interface functions to the termination layer.

The documented port set on ABB NTMP01 consists of two isolated RS-232-C ports and one non-isolated RS-485 port. ABB also identifies the unit in BRC use-with records and lists NKTU when required by the installed arrangement.

Before integrating ABB NTMP01, establish the required serial standard, DTE or DCE jumper position and controller interface. Isolation differs between the RS-232-C and RS-485 paths, so grounding and cable decisions must follow the selected port.

Technical notes
Select the NTMP01 port before designing or restoring a serial link: both RS-232-C ports are isolated, while the single RS-485 port is non-isolated. For INIIT12 or INICT12 paths, the termination-unit jumpers determine DTE or DCE operation. Match the controller, NKTU cable, grounding and port settings before communication testing.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Where should diagnosis begin when only the RS-485 device connected through NTMP01 loses communication?
Start with the non-isolated RS-485 path, its common reference, cable pinout and external-device settings before disturbing the two isolated RS-232-C circuits.
Why does the isolation difference matter for NTMP01 wiring?
The RS-485 path is not isolated like the two RS-232-C paths, so grounding and common-mode conditions require separate review.
How is DTE or DCE operation selected on NTMP01?
For documented transfer-module paths, jumper configuration on the termination unit determines the serial equipment role.
What evidence is needed before NTMP01 is assigned to a BRC controller installation?
Use the ABB use-with record together with the cabinet cable, transfer-module and network configuration; a controller label alone does not prove the full interface.
What should be checked when an NTMP01 serial link remains inactive?
Confirm port type, DTE/DCE jumpers, cable pinout, grounding, external-device settings and the controller or transfer-module configuration.
How should the Cnet role be reviewed before replacing NTMP01?
Document the two connected network contexts, transfer module, serial path, cable and configured communication settings before removal.
