Data Sheet
10.4.2 Monitoring of Auxiliary Devices
The DPM can read status information of the Auxiliary Devices via the PG0…PG3 inputs.
The
PG0…PG3 are digital 3.3V compliant inputs with internal pull-up resistors. Logic high input on a PGX
pin should correspond to normal operation of an Auxiliary Device.
Status monitoring data of Auxiliary Devices is stored in the DPM and displayed in the IBS Monitoring
Window shown in Figure 11.

10.4.3 Run Time Counter
The DPM also monitors the duration of time that it has been in operation. The 4 bytes Run Time
Counter is active whenever the DPM is powered up. The count rate is 1 second. The counter is loaded
into RAM upon power-up and the new count state is periodically saved to the non-volatile memory.
Contents of the counter can be examined in the GUI IBS Monitoring Window shown in Figure 11 or

directly via the I
C bus using specific commands.
