AT begins when the AT Execute/Cancel parameter is changed from
OFF to 0.
While AT is being executed, at flashes on Display No. 1. Display No. 2
shows the PID set number currently being used for control. When AT
ends, the AT Execute/Cancel parameter goes OFF and the display
stops flashing.
To stop AT, select off (AT Cancel).
If you attempt to move to the Operation Level and display the PV or SP
while AT is being executed, Display No. 2 will flash to indicate that AT
is being executed.
• Only the Communications Writing, Run/Reset, AT Execute/Cancel,
and Auto/Manual parameters can be changed while AT is running.
No other settings can be changed.
• If the Run/Reset parameter is set to "Reset" while AT is being
executed, AT will stop and operation will stop. If "Run" is then
selected, AT will not resume.
• If an input error occurs while AT is being executed, AT will stop. AT
will run again after recovery from the error.
