Operation
DANGER
There is danger to life if the device is not used correctly!
Comply with the special explosion protection conditions.
Only operate within the approved temperature range.
In case of bus failure (communication fault) the outputs switch
to failsafe mode (switch to 0, and get turned off).
In failure the device must be closed down.
Addressing
The PROFIBUS-DP address can be set in the range from
01 to 99 using the rotary switches x1 and x10.
An address change will be applied when the power is back
on.

Diagnostics
The module provides on request (SlaveDiag-Request)
diagnosis data (SlaveDiag-Response) to the master,
which contains also besides standard diagnosis, module specific
diagnosis:

(communication status, master address,

The allocation of the bits (Unit-Diag-Bits) in byte 9 and 10
to the channel number is fixed in the GSD.
Note: The bit 28 (U2) will be set, if the supply voltage U2
(terminals U2+,U2-) is missing.
Example: With mistake (open circuit/short circuit) in channel 6 the
bit 21 will be set to 1.
