Undershooting underrange limit value channel 1
Results from the limit value monitoring before the comparison of the process data in the calibrated
range. If the configured limit value is undershot, this bit is set.
0:
Underrange limit value is not undershot.
1:
Underrange limit value is undershot.
Exceeding of overrange limit value channel 1
Results from the limit value monitoring before the comparison of the process data in the calibrated
range. If the configured limit value is exceeded, this bit is set.
0:
Overrange limit value is not exceeded.
1:
Overrange limit value is exceeded.
Output driver error 1 (COM) channel 1, common mode overrange
This bit is set if the 24 V field power falls bellow 20 V.
0:
No output driver error 1 (COM)
1:
Output driver error 1 (COM) present.
Output driver error 2 (LAST) channel 1, load error
This bit is set if there is a short circuit on the output.
0:
No output driver error 1 (LAST).
1:
Output driver error 2 (LAST) present.
Output driver error 3 (TEMP) channel 1, over temperature
This bit is set if the permissible temperature of the output driver was exceeded.
0:
No output driver error 3 (TEMP)
1:
Output driver error 3 (TEMP) present.
Error 24 V Field supply voltage
This bit indicates an invalid state of the field-side power supply. In mode 6 ... 18 V, the
undervoltage detection threshold is inherently slightly higher (at approx. 20.5 V). The module
outputs the desired voltage value when this threshold is indicated, however this value will not
exceed the value that is still technically possible. The input voltage must be approximately 2V
higher than the desired output voltage.
0:
24 V Field supply voltage OK.
1:
24 V Field supply voltage too small.
Group error channel 1
If one of the channel-related status bits is activated, this bit is also set to 1.
0:
No group error.
1:
Group error present.
