ALARM INDICATOR MASK P1/1
The Alarm Indicator Mask screen includes the parameters that determine which alarms and which numerical
comparator outcomes will cause the ‘alm’ to flash in the lower-left corner of the screen. The two parameters
are bit mapped for each condition. Place a ‘1’ in the bit position corresponding to the alarms or compares
that you want to activate the ‘alm’ indicator. In this case, a ‘0’ in the bit masks (or disables) the condition
from activating the ‘alm’ indicator. Refer to Appendices: Appendix C for the Std Alm Msk (CP-375) and
CustAlm Msk (CP-376) bit map list.
Std Alm Msk
The Standard Alarm Mask (CP-375) allows you to mask out specific alarms so that they will not cause the ‘alm’
indicator to flash (in the lower left-hand corner of the CX-1200 screen) by entering a “0” in the corresponding bit
position. You can also activate any of these alarm conditions by entering a “1” in the corresponding bit position.
Refer to Appendices: Appendix C for the Alarm Mask (CP-375) bit map list.
CustAlm Msk
Custom Alarm Mask (CP-376) allows you to mask out the compare results so that they will not cause the ‘alm’ indicator
to flash (in the lower left-hand corner of the CX-1200 screen) by entering a “0” in the corresponding bit position. You
can also activate any of these compare conditions by entering a “1” in the corresponding bit position. Refer to
Appendices: Appendix C for the Compare Mask (CP-376) bit map list.
