The ABB SPIIT13 is a high-performance communication module built for the Symphony Plus and Harmony Rack automation series to execute direct communication routing between discrete rings or networks. Functioning as an INFI-NET to INFI-NET Local Transfer Module, this unit establishes a deterministic data bridge that transfers time-critical process values, control commands, and system diagnostics locally between separate system rings without routing latency. Equipped with an onboard lithium button cell battery to maintain volatile configuration memory during master power cycling, this module provides the dependable backplane-to-network data bridging required to keep large-scale distributed control systems fully synchronized and operational.

Isolate the rack housing assembly from all live power paths before attempting insertion or extraction of the communication card. Live insertion risks causing instantaneous backplane bus disruptions, data frame loss across the broader INFI-NET loop, and structural hardware degradation due to transient electrical spikes.
