Configuring counters
Overview
You can configure the energy counters of the AI Energy Meter 480VAC ST as follows:
● Activate / Deactivate
● Start / stop counters using gate
● Set and reset start value
Energy counter gate
You have the option of starting and stopping the energy counter using the gate. To this
purpose you have to:
● Select the "Enable gate control for the energy counter" parameter in the configuration of
the AI Energy Meter 480VAC ST.
● Set the DQ bit for the "counter gate" in the user data in Control byte 1 of the output data
(Bit 6 in Control byte 1).
The "Enable gate control for the energy counter" parameter and the DQ bit for the "counter
date" behave like the parallel connection of contacts.
Image 7-1 Gate enabled
If you deselect the "Enable gate control for the energy counter" parameter in the
configuration of the AI Energy Meter 480VAC ST, the energy counters operate
independently of the DQ bit as long as the current value lies above the configured "Low limit
for measuring current".
