3.2.11 Control output setting at CPU stop error occurrence function
(1) You can set the Q62HLC control output (HOLD/CLEAR) to be provided when
the programmable controller CPU has generated a stop error.
(2) To make this setting, use the intelligent function module switch setting on GX
Developer.
• CLEAR : Stops the PID control, temperature judgement and alert judgement
functions and turns off external outputs.
• HOLD : Continues the control status prior to a programmable controller CPU
stop. For example, when PID control was exercised before a
programmable controller CPU stop, PID control is continued if the
programmable controller CPU stops.
Refer to Section 4.5 for details of the setting method.
