ABB INNPM22 | Symphony Network Process Module

The ABB INNPM22 is a Network Processor Module used in ABB Bailey INFI 90 and Symphony control-system architectures. It functions as a network-processing interface between the control network and the controller-side communication architecture. ABB documentation identifies the INNPM22 as an INFI-Net network processor module, while the later SPNPM22 provides the corresponding fit-and-function replacement within Symphony Plus.

The module is designed to work with the INNIS21 network interface module. Together, these modules provide a Harmony control unit with access to the Control Network (Cnet). This makes the INNPM22 suitable for communication, network processing, controller integration, and maintenance of compatible legacy ABB Symphony control systems.

❓ Common Questions & Answers

Q: What is the ABB INNPM22?
A: It is an ABB Network Processor Module used in INFI-Net communication architectures for compatible Bailey and Symphony control systems.

Q: What does the INNPM22 do?
A: It provides network-processing functions that allow the associated control unit to communicate through the control network.

Q: Which module works with INNPM22?
A: The INNIS21 Network Interface Module is the associated network interface. ABB documentation describes the INNIS21 and INNPM22 as the main modules of the Cnet-to-HCU interface.

Q: Is INNPM22 compatible with Symphony Plus?
A: The later SPNPM22 is documented as a fit-and-function replacement for the INNPM22. Compatibility should still be confirmed against the specific system configuration.

Q: Is INNPM22 an I/O module?
A: No. It is primarily a communication/network processor module rather than a conventional analog or digital I/O module.

Q: What should be checked before replacement?
A: Confirm the complete part number, rack type, associated INNIS21 module, firmware/software requirements, network configuration, and existing system architecture.
