4.6.5 Modbus General Setup Registers

Registers in this block control general setup parameters of the IO-FEP2. They are stored in the SETUP.TXT file on sd-card. Most of the parameters are character strings which must be 0-terminated.

Unused IP address parameters (e.g. for NTP or trap destinations) must be set to '0.0.0.0'. The same value the IO-FEP2 assigns if an IP address string cannot be parsed.
