Modbus TCP can be operated as a server and as a client at the Ethernet connection of
the Fieldgate FXA42.
When operated as a Modbus client, up to 32 devices and 256 values can be defined.
As values can become arrays when reading and writing several registers or coils, the
following limit applies: The number of all scalar (non-array) values plus the size of all
arrays must not exceed 512.
