Using RTAC for polling Modbus device. I have list of registers for Modbus device. Tried to configure points under Holding registers, reading the polls, and no success. Registers 40001-40019 are Analogs, (16 bit) 40020 bit 0 thru 40163 bit 15 binaries. Kind of understand that Under read holding registers I can configure these points. Another place for configuring these registers are for Polling# of registers. Like I said, have no experience on Modbus. Any help will be appreciated.
