2.6.3 MODBUS TCP Communication Standards
1. The supported function codes and communication addresses are the same as RS485. Please refer to
the RS485 communication section in Appendix A.
2. Since DTME08 / E04 is an IP address resolution machine, when editing communication instructions,
the address of its RS485 station number can be written to any value.
Example: If you want to use the Ethernet Modbus of DTME08 for communication function to read the
PV value of 8 channels, you can issue the command [FF 03 0268 0008]. The “FF” part can be modified
to any value. Only when using RS485 for communication, you need to confirm the station. The value
of the number selector (see section 2.4).
