Setting the operating mode
Due to a necessary synchronisation of internal processes, the change of operation mode
can require some cycle times of the controller. We therefore recommend that you always
verify and wait for reception of the desired operation mode.

Table 3.12 Operating mode
Faulty return values can be called up due to invalid values that do not come from the

command.

Before activating the RS-485 interface, please make sure that you
are using a completely wired null modem cable. All pins of the
