NF3500G4 and scripting for ModBus
Hi guys,
I'm working with 4 NF3500G4 controllers each connected via breakers to boat pedestals that provide power to a waterfront area. What I'm trying to do should be simple, but I've hit a brick wall. I would like to TCP script Modbus control to check the status of the breaker/zone and then turn the breaker/zone on and off via a web interface with the ultimate goal of users being able to purchase X hours of service and automating on/off. I was sent a G4 Control Module Register List by our Schneider rep but it's getting me nowhere. At this point I'm wondering if I'm missing something. So far I've scanned multiple zones and multiple registers on the provided list but nothing returns the breaker/zone status that matches what is provided by the web interface. Any help is very much appreciated.
