4-22 Logic Operations
4-22-1 The Logic Operation Function (CX-Thermo)
• The logic operation function logically calculates as 1 or 0 the Controller
status (alarms, SP ramp, RUN/STOP, auto/manual, etc.) and the external
event input status, and outputs the results to work bits. The work bit status
can be output to auxiliary or control outputs, and operating status can be
switched according to the work bit status.
• Work bit logic operation can be set from 1 to 8. Set them to No operation
(Always OFF) (the default) when the work bits are not to be used. When
logic operations are being used, a dot will be displayed on the No. 2 dis-
play of the adjustment level display
