Chapter 9 Logic Controller Application Example with Explicit Messaging
To have the CompactLogix controller energize OUT A of the EC4 Current
Monitoring Relay using I/O Messaging, set Bit 0 in Word 1:O.Data[0] to a 1.
OUT A should be energized.
To verify that OUT A of the EC4 Current Monitoring Relay was energized, the
CompactLogix controller will read the device status of the EC4 Current
Monitoring Relay and place that information at Word 1:I.Data[0] with the
L32E. Bit 2 identifies the state of OUT A.
