3.3 Additional IHP24 FF-Fieldbus Menu Function
Internally in IHP24 there is a hardware Foundation Fieldbus module. This module communicates
with the rest of the hardware in IHP24 via a local Modbus interface. This interface needs to run at a
fixed setup ID = 1, Baud rate = 38400, Parity = Even, Stop bits = 1. The communication settings
should always be set to these values.
It is important to set the Baud rate after an “Advanced Reset” of the IHP24.
