Digital Input Sequence Of Events - Honeywell Experion 8 Series Technical Information

Series 8 Controller and I/O Specification, S803-150-500
3.3.8.

Digital Input Sequence of Events

Function
The Digital Input Sequence of Events (DISOE) accepts 24VDC discrete signals as discrete inputs. The inputs can be
time tagged to support 1ms resolution Sequence of Events
Notable Features

Three modes of operation
Normal (20ms PV scan)
o
Sequence of Events (1ms resolution SOE,
o
20ms PV scan)
Low Latency (5ms PV scan)
o

Extensive internal diagnostics for data integrity

Optional redundancy
