Overview Manuals Specifications Remote Link Design Port Assignment Failover Planning

Features:

  • Remote Cnet bridge: Joins central and satellite network interfaces over RS-232-C.
  • Defined port roles: Separates system-only traffic from a system or diagnostic port.
  • End-to-end redundancy: Duplicates interface hardware on both participating networks.
ABB INIIT12 supports network-to-network communication where the satellite Cnet is not connected by a local cabinet cable.

The serial transport equipment sits between two INIIR01 interfaces, making configuration symmetry across both endpoints essential.

Maintenance teams should evaluate the entire remote path, because a healthy board cannot compensate for mismatched jumpers, link equipment or endpoint settings.

For ABB INIIT12 review, provide drawings and settings for both the central and satellite interfaces, including external serial equipment.

Central-to-Satellite Topology:

  • Central side: An INIIR01 interface attaches to the central Cnet.
  • Satellite side: A second INIIR01 interface attaches to the remote Cnet.
  • Transport: RS-232-C traverses the selected modem, transceiver or satellite equipment.

NTMP01 Serial Access:

  • Port one: System data only.
  • Port two: System data or diagnostics.
  • Electrical role: NTMP01 jumpers determine DTE or DCE operation.

Duplicate Interface Sets:

  • Per network: Two INNIS01 and two transfer modules are required.
  • Supervision: Dedicated Controlway carries primary/secondary monitoring.
  • Transition: The secondary takes responsibility when it detects primary failure.
Description
A central-to-satellite Cnet path uses ABB INIIT12 with an INNIS01 to build each INIIR01 remote interface. The complete route places one interface on each network and joins them through RS-232-C equipment such as modems, transceivers or a satellite link.

Two RS-232-C ports on the NTMP01 termination unit support the ABB INIIT12 link at user-selectable rates up to 19.2 kbaud. Port one carries system data, while port two can carry system data or serve as a diagnostic port; function code 202 determines many operating characteristics.

Redundant deployment of ABB INIIT12 requires duplicate INNIS01 and transfer modules on both networks. The secondary monitors the primary over dedicated Controlway, so procurement and commissioning must cover the complete central and satellite interface sets rather than only one board.

Technical notes
Deploy ABB INIIT12 as a matched central-to-satellite interface, not as a single serial card. Verify INNIS01 pairing, NTMP01 DTE or DCE jumpers, function code 202, modem or transceiver settings and both network addresses; redundant service requires duplicate module pairs at each end of the link.

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.
What modules form an INIIT12 remote Cnet interface?
One transfer module works with one INNIS01 as an INIIR01 interface. A remote connection needs an interface at both the central and satellite networks.
How are the two serial ports used by INIIT12?
Port one carries system data only. Port two may carry system data or provide diagnostics, with both ports presented through NTMP01.
Which link equipment can be used between two INIIT12 interfaces?
ABB describes modems, microwave equipment, transceivers and satellite links as possible RS-232-C transport methods between central and satellite networks.
What limits the communication rate of INIIT12?
The official data sheet specifies a user-selectable rate up to 19.2 kbaud; the external equipment and serial configuration must match at both ends.
What hardware is required for redundant INIIT12 communication?
Each network needs two INNIS01 modules and two transfer modules. The secondary monitors the primary over dedicated Controlway and takes over after a detected failure.
Why can INIIT12 communicate locally but fail across the remote link?
Compare DTE/DCE jumper selection, cable pinout, port role, baud settings, external modem or transceiver state, addresses and function code 202 configuration.
What should be documented before servicing INIIT12?
Record both network interfaces, serial equipment, port settings, function-code configuration, redundancy state, healthy diagnostics, cable routing and recovery test steps.
