Process Data Outputs
The 24 solenoids are represented by one bit each and they are grouped in 3 Bytes. The LSB (Least Significant
Bit) is associated with Solenoid-1 and the MSB (Most Significant Bit) is associated with Solenoid-24.

Manufacturer Specific Object “System Command”
The Manufacturing Specific Object “System Command” is used for specific functions, such as: “Leave Failsafe /
Error Acknowledgment” and “Store Switching Cycles Counters”, as detailed in the table below. In order to
execute the desired function the specific value associated with the command has to be written in the Object.
Command Value Command Name Description
0x01
Leave Failsafe State
(Acknowledge Error)
This command allows the module to leave failsafe state*
(acknowledge error). Meaning that, if no error is pending
at the time the Leave Failsafe State command is executed,
then the device returns to normal operation and the
outputs are set according to process data.
* If Failsafe state is reached, then it is not automatically left if the error
conditions are no longer existent.
0X02 Store Switching Cycle Counters
When this command is executed, the current values of
the switching cycle counters are stored into EEPROM. This
command is intended to be used before powering off the
device.
The System Command Byte supports the commands as defined in the table below.

Manufacturer Specific Object “Switching Cycles”
The Manufacturing Specific Object “Switching Cycles” contains the 24 switching cycle counters for the valves.
The counters values are automatically stored by the module every 30 minutes.
* Max value for each counter is circa 4,3 billion (UDINT max representable value). Once that the max value is
reached, this is held in memory and additional cycles are not recorded.
