Product Description:
The Harmony control unit interface consists of the INNIS01 Network Interface Module and the
INNPM12 or INNPM11 Network Processing Module (Fig. 4). This interface can be used for a node
on the central network or on a satellite network (Fig. 1). Through this interface the Harmony control unit has access to Cnet and to Controlway at the same time. Controlway is an internal cabinet
communication bus between Harmony rack controllers and the communication interface
modules.
The HCU interface supports hardware redundancy. Redundancy requires a full set of duplicate
modules (two INNIS01 modules and two INNPM12 or INNPM11 modules). The secondary network processing module (INNPM12 or INNPM11) continuously monitors the primary through a
direct ribbon cable connection. A failover occurs when the secondary detects a primary module
failure. When this happens, the secondary assumes responsibility and the primary is taken offline.
