5 Advanced Operations
5-22 Logic Operations
5-22-1 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 between the first two digits on the No. 2
display of the Adjustment Level display
Note: The four numeric digits to identify the product code are displayed in the No. 2 display.
