Has anyone ever interfaced with an Electro Industries brand Nexus 1250 power quality meter?  Looking for the easy way out without having to trudge through hundreds of pages of modbus mappings.

Hey ssilk,

I wasn't able to find any drivers for that power quality meter on our Instrument Driver Network (www.ni.com/idnet), so hopefully there are other customers who have used this piece of equipment before that can help you. If you do end up having to program a modbus interface, you have a couple options (all of which assume you're using LabVIEW or CVI) : 1) Program using NI-VISA. Modbus communication is essentially serial communication, so look at some of the example programs we have for serial communication. 2) Program using the free Modbus library that we provide (https://forums.ni.com/t5/Reference-Design-Content/LabVIEW-Modbus-API/ta-p/3524019). This is easier than the first step, but does require you to have some knowledge of the Modbus protocol. 3) Purchase the Datalogging and Supervisory Control Toolkit (now part of LabVIEW Professional). This is by far the easiest way to program a Modbus application, as you simply read from and write to simple I/O nodes in LabVIEW. Good luck!
