Hi all,
recently I found the PFC-Modbus-Server and this flow that I was able to fit to my needs, that is, to get measurement data from multiple 750-494 power measurement modules attached to a PFC200. Now, I want to adjust the current transformer ratio of phase L1, L2 and L3 and according to the manual this is done by adjusting registers 39-41 and register 32 bit 12-14. But I am unable to figure out on how to do this using the Modbus-Server. I am assuming this is somehow done transmitting the output data using the Control Words (the same way the measurement data is gathered), since Bit 7 of Byte 0 can be set to 1 for ´Register Communication`, but there are no further instructions on how to actually change the value of a register.
I really hope somebody could help me with this!
Kind regards
