10.15.1 Modbus/TCP server
After successful start of the Modbus/TCP server, an external client can access
registers, flags, inputs and outputs.
This chapter covers the addressing process and describes the commands
supported by the Modbus/TCP server.
Four connections may be opened at the same time.
Modbus/TCP only supports transmission of registers with a width of 16 bits.
From this follows, that only the 16 least significant bits are transmitted when
32-bit registers are sent.
When assigning incoming register values to the internal 32-bit registers no
sign extension will be carried out.
