Hi I am writing to enquire about a problem that bothers me. I am new to the "ladder" programming, but as I have one V570module and one VFD powerflex in my possession, I have decided to link them as master and slave. I have examined the examples of modbus communication and I did the following scheme. It is functioning, but I would like to know is there a better way to write and read in several registers at once?
