Programming ION Meter with Self Read Integrators

[N4th4n13L]

The following instructions will help you setup your ION meter with end of day self reads. These are the cumulative registers that MV90 and other billing systems will use for your stop read, and setting them up as end of day reads will ensure that MV90 stop read is the energy read at end of day rather than time of interrogation.

First, the integrators used for stop reads are also commonly used by your meter displays, DNP and Modbus maps, and TOU energy frameworks. We can take 2 approaches to setting up the meter; create new self read integrator modules or re-map other existing frameworks and modules to different or new integrator modules.

Most ION frameworks use integrator modules 1, 2, 5, and 6 as the cumulative or stop read integrators when the load profile is data is downloaded. To convert the integrator modules to end of day self reads. Map the Update Outputs inputs register to the Clock 1 CL1 New Day output register. The register itself is still constantly integrating, but the outputs will only update at 24:00 each day.

If you want other displays, mappings, and frameworks to use a different register you’ll need to lookup their connections and re-map to the appropriate integrator module.

If you take the route of adding new integrator modules and setting them up for end of day self reads. You’ll also need to make sure the billing system is setup to use those integrators instead of the previous cumulative registers used for stop reads. For MV90 this is done through the encoder type field in MV90. For each channel you’ll need to specify the new integrator module number. For example, if you create 4 new integrators: Integrator 96 (kWh del), Integrator 97 (kWh rec), Integrator 98 (kVARh del), and integrator 99 (kVARh rec). The channel setup for kWh del interval reads will use 96 for the encoder type field, 97 for the kWh rec interval channel, 98 for the kVARh del interval channel, and 99 for the kVARh rec interval channel.
