Settings on the HHU for software version 4.x and higher

The settings for "baud rate" and "bus address" parameters made with switches
S1 and S2 on the HHU no longer apply to software version 4.x and higher.
These bus parameters can be reconfigured from this software version
(cf. Section 3.4.3).
3.4.3 Configuring the HHU, setting interface parameters
The GD parameters must be set before the submodule can communicate via
the MPI interface. The setting can be activated during power-up (i.e. while wait-
ing for the first GD message frame from the PLC ("Waiting for PLC" state) via
the HHU interface by means of key combination Jog
(top far right). The individual parameters are then interrogated via the HHU dis-
play and entered via the HHU keyboard. You can change the default values
with the + and – keys within the permitted value range. You can switch to the
next parameter with the Automatic
causes the preceding parameter to be stored in the Flash EPROM. The param-
eters need therefore only be set during start-up and when interfaces are
changed. If the interface parameter settings are not activated after power-up,
the stored values are used or the default values (see table) loaded.
