Modbus TCP
If Modbus TCP is activated in the configuration, the ports (relays, outputs, eFuses) can
be switched and the following data is callable:

This chapter is general for all Gude devices. Depending on the device type, some
ports or certain sensors are not available.
All calculations in this chapter are based on addresses starting at "0". For some
Modbus TCP Utilities, however, the addresses start at 1, in which case a 1 must be ad-
ded to the addresses in this chapter. Please try both possibilities for tests!
The Unit-ID is ignored because the device is uniquely identified by its IP address.
