Currently OUT A of the E3 Plus Overload Relay is energized as shown in Bit 2 in
Integer_Files[0].
Reading Device Status using the Control Supervisor Object Class
(0x29)
In this example, a Periodic Task has been configured within the L32E to execute
every 1000 ms in which a message instruction will be used to read the Device
Status of the E3 Plus Overload Relay using the Control Supervisor Object Class.
The supporting ladder logic was added to execute a MSG instruction every time
this Periodic Task executes.
The Device Status is located in Parameter 21 within the E3 Plus Overload Relay.
Set up the MSG instruction in the Configuration tab to read Parameter 21 using
the Control Supervisor Object Class by configuring the following fields:
