System values
This menu displays the status of system values that are available for selection as the source for func -
tion input variables and CAN and DL outputs.
The system values are divided into 5 groups:
General system values
When programmed accordingly, these system values allow monitoring of the controller system.
Controller start generates a 20 second pulse 40 seconds after the device is switched on or reset, and
is used for monitoring the controller starts (e.g. after power failures) in the datalogging feature. The
interval time in datalogging should be set to 10 seconds for these starts.
The
sensor errors and network errors are global digital values (No/Yes) which are not connected to
the error status of a specific sensor or network input.
If any one of the sensors or network inputs has an error, the status of the corresponding group chang
-
es from No to Yes.
The pulse values generate a single pulse per time unit.
• Controller start • CAN node
• Sensor error inputs/CAN/DL • CAN connection
• Network error CAN/DL • Message (type: message/warning/fault/error)
• Mains frequency • Serial number
Time system values Date system values
• Second (seconds of the current time) • Day
• Minute (minutes of the current time) • Month
• Hour (hour of the current time) • Year (without the century)
• Second pulse • Day of the week (starting with Monday)
• Minute pulse • Calendar week
• Hour pulse • Day of the year
• Summertime (digital value OFF/ON) • Day pulse
