Hi, I have an IOC that is supposed to control a Siemens S7 PLC using s7plc (1.4.1) and modbus (3.0.0), developed by someone that is not me. I have been running into two (possibly separate but
I don’t think so) issues. First some errors during set up: # portName, tcpPortName, slaveAddr, modbusFct, addr, length, dataType, pollMsec, plcType, drvModbusAsynConfigure("ESS_NBLM_PLC502_AS_WRITE_0", "ESS_NBLM_PLC502", 1, 16, 0, 40, 8,
