I'm polling the meter for voltages and currents, Mw, Mvars, and pf. The configuration screens in the RTU only asks for accumulator or analog. The meter answers and sends back some counts, and the registry types, but not all the returned info seems valid. The protocol of the meter is Qdip, which appears to be proprietary so not much info is available online. I've got the manual for the meter but it doesn't tell how the port gets its registers to send to the RTU, as far as I can tell. I'm not the department that programs the meter and I need to be able to convince those that do program it to change the registers they are sending to the com port. So does anyone have expertise with Qdip protocol and the inner workings of this meter? How are the registers laid out?
