In the PNOZmulti Configurator you can define limit values, which are to be monitored:
} Range monitoring
With range monitoring you can define the permitted value range. You can define up to 4
range limits (e.g. <3 mA monitored for open circuit; I > 21 mA monitored for encoder er-
ror). Depending on the selected condition ("greater than" or "less than"), the ENBL out-
put bit and output bits 1 - 8 for threshold value monitoring are set to "0" if the recorded
value exceeds or drops below a range limit. An entry is added to the error stack.
Exception: If "automatic start" type has been selected, no entry will be added to the er-
ror stack.
} Threshold value monitoring
You can define up to 8 switching thresholds, which can be used to monitor certain pro-
cess variables (e.g. different temperature values). The thresholds can be configured
with or without scaling. 2 threshold values are configured per threshold. One threshold
value defines when the relevant output bit (1 ... 8) is set to "1". The second threshold
value defines when the output bit is reset to "0". No entry is added to the error stack.
The exact analogue values are made available to the base unit to forward to a fieldbus.
This value is transmitted through a single channel and is not safety-related. It can be used
for diagnostic purposes.
