Appendix D Digital and Analog Energy Add-On Instructions
When the total pulses equal 10 million, the rollover rung resets the total energy value, VAL_Total_ xxx.
PowerMonitor Digital Status Input Logic
The following logic is included in all Energy_ xxx_PM_Status Add-On Instructions to read the energy values from a
PowerMonitor status input.
An explicit message reads the status inputs from the PowerMonitor 1000, 3000, or 5000 device. A PLC-5 Typed Read
message is configured to read one of the status inputs when adding the Add-On Instruction to your logic. Refer to
page 326
for details on configuring the message instruction. The destination tag of the message must be input back into the
instruction through the Inp_Status_Input tag. The PowerMonitor status inputs are counters that total the number of
incoming digital pulses. No additional logic is required to calculate total consumption as the digital pulse is scaled in the
advanced parameters of the PowerMonitor. The Inp_Status_Input value is simply moved to the Val_Total_
xxx tag (Total
Consumption).
