Overview

The Maxiflex M1761A 32SOE Sequence-of-Events Module monitors 32 Digital Inputs and creates time-stamped events to a resolution of 1ms upon change of state.

The 32SOE module is connected to the field wiring through a multicore cable (Model C1467B) connected to a remote terminal board (Model C6332B). This has the advantage of providing compact field termination in the most convenient location in the wiring cubicle saving panel wiring cost, space and construction time.   The terminal board also provides ribbon header outputs to repeat the input status to an Omni16C Annunciator/Remote Display via a ribbon cable (Model C1432-2).

By using multiple 32SOE modules with the Maxiflex P3 CPU, powerful Sequence-of-Events systems can be constructed with up to 480 Time-Stamped inputs per system. Multiple systems can be linked and time synchronised for larger distributed systems.

The 32 inputs can be used as regular digital inputs within the P3 processor as well as independently generating change-of-state events on the module.

A buffer of up to 1000 events on each module ensures that avalanche conditions in the application cannot overflow the module.

Events from all 32SOE modules in a single system are sorted by the P3 CPU into correct time order, and then passed to the event logging computer for display and storage.

The 32SOE module and P3 processor are compatible with the Omniflex Conet OPC Server and Omni4000 Alarm and Event Management Supervisory Software.

The Conet OPC server reads the events time-stamped within the 32SOE module to 1ms and passes these events with time-stamp right up to the OPC Client.
