Good evening, Im doing a small school project in which i need to communicate with a PAC3100 Power Meter via its modbus interface with an arduino, and then use said information to transmit it via wifi to an app/html site/LAN IP (still don't know which one to use). My problem is that i can't stablish communication with the Power Meter.. I'm trying with two different codes with two different libraries each (seeing which one works first) but for both i need to stablish a register address in order to access its correponding information. The information that i´m trying to acces is the voltage a-n, b-n, c-n,current a, b, and c. I read in the PAC's manual (Appendix A.2) that i need to use offsets 1, 3, 5, 19, 21 and 23, but are these the addresses all that i need to input? beacuse i can´t seem to be able to read the INPUT REGISTERS or stablish any connection at all... I feel that i need to add something else to those offsets though i´m not very sure of what that could be... For example, in a Schneider PM (link below) they put the exact addresses to input for, but i can´t seem to find them anywhere on the PAC´s manual, just the Offsets. Any help would be very appreciated To clarify, i did post a similar question to this in Arduino´s Forum but i haven't been able to get an exact answer, i did get some help in clarifying some things though. https://forum.arduino.cc/index.php?topic=601774.0 https://www.schneider-electric.com/resources/sites/SCHNEIDER_ELECTRIC/content/live/FAQS/276000/FA276938/en_US/EM6430_User_Manual_NHA12535-03.pdf The libraries i'm using are SimpleModbusMaster and ModbusMaster Edit: Added SimpleModbusMaster's Manual AttachmentSimpleModbusMasterManual.pdf (368 Downloads) |
