The T100M+ PLC supports a subset of the OMRON and MODBUS (Both ASCII and RTU modes are now supported) compatible communication protocols so that it can be easily linked to third-party control software/hardware products such as SCADA software, touch panels etc. The PLC automatically recognizes the type of command format and will respond with the correct response. These are accomplished without any user intervention and without any need to configure the PLC at all! Both MODBUS and Omron protocols use the same device ID address (00 to FF) as the native protocol described in Chapter 3. Since the addresses of I/O and internal variables in the T100M+ PLC are organized very differently from the OMRON or Modicon PLCs, we need to map these addresses to
