Output Fallback State Configuration

In case the 140 SDO 953 00S module detects a discrepancy in the data from the
host, the module sets its outputs to configured fall back state.
The outputs of the 140 SDO 953 00S module have three states.
energized
de-energized
"maintain last state" (fall back state)
In the parameter configuration screen of the Unity Pro, you can configure the output
position in case the module is no more serviced by the processor module. You can
either maintain last value or define another value

The health word is an extra system control generated by the processor module,
using the data read from the output module.
Any of these errors activates the health word:
overload problem (activates only the corresponding bit of the health word)
unsafe channel (activates only the corresponding bit of the health word)
malfunction of the host (SSD)
process power supply problem
CRC error
incorrect exchange numbe

The following diagram shows the register of word 7.

Bit 15 to bit 0: These 16 bits are set to 1 when no error is detecte

The following diagram shows the register of the third input word. If bit 15 is set to 1,
it means that f the internal checks have detected a malfunction of channel 1, etc.

On word 4, bit 15 is dedicated to the Process Power supply Error. It is set to 1 if
the external power supply is no longer detected.
On word 4, bit 14 is dedicated to the System Shut Down. It is set to 1 if the module
has detected a malfunction from its host. In that case, the module is safe and shuts
down.
The other bits on word 4 and words 5 and 6 are used by the module for internal
checking:
Exchange number: serial number of the set of data
Cyclic Redundancy Check (CRC): function used to detect errors after
transmission
