PowerMonitor Digital Status Input Logic

The following logic is included in the Energy_Elecric_PM_Status Add-On Instruction to read the kWh value 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. Additional logic is not required to calculate total consumption as the digital pulse is scaled in the
advanced device parameters of the PowerMonitor. The Inp_Status_Input value is moved to the Val_Total_kWh tag.
