ABB INNPM-12 Programmable Logic Controller Module

The ABB INNPM-12 Network Processing Module is a legacy Bailey/ABB Harmony rack module that, together with an INNIS01 Network Interface Module, provides the Cnet-to-HCU interface for ABB Bailey's Symphony Enterprise Management and Control System. In the Harmony architecture, the INNPM12 functions as the dedicated network processor in the Harmony rack, enabling the Harmony control unit to access the Control Network (Cnet) used by Symphony. The two components—INNIS01 Network Interface Module and INNPM12 Network Processing Module—are designed to reside in a Harmony rack and work in concert to connect the Harmony control unit to the Control Network within Symphony EMS/Control System. This INNPM-12 model is part of the broader ABB Bailey Controls lineage, tied to ASEA BROWN BOVERI branding before ABB’s consolidation of the Bailey ecosystem.
