Description

Product Overview

The INNIS01 (NIS) is the fiber communication front-end slave module paired with INNPM01 (NPM). It physically connects the PCU to the dual-fiber INFI-NET token-passing plant loop, handling serial packet transmission, CRC checking, retransmission and loop fault isolation. It receives packaged messages from INNPM01 and transmits them onto the fiber ring; inbound traffic is forwarded back to NPM for distribution to local controllers and I/O. Dual fiber ports support redundant ring topology, so a single fiber break will not bring down the whole network. It is widely stocked legacy spare for power, pulp & paper, refinery and chemical DCS plants.
