%M12260

ATMANIN

Autotest Manual Initiate

Initiates a single autotest (both

 

 

 

input and outout) any time it is

 

 

 

turned on, even if the Autotest

 

 

 

Inhibit bit is on.

 

 

 

 

%M12261

ATINHIB

Autotestinhibit

Preventstheªautomaticºautotest (both input and output) from oc- curring at the Autotest Interval specified in the GMR Configura- tion for as long as this bit is On. Note: it does not prevent an Au- totest Manual Initate.

SDCAN

CancelI/OShutdown

If an I/O Shutdown was initiated

 

 

 

by any PLC, turning this bit On

 

 

 

cancels it and prevents the shut-

 

 

 

down from occurring. If this bit is

 

 

 

setcontinuously, no I/O Shut-

 

 

 

down will be initiated.

 

 

 

 

%M12266 to %M12288

Reserved for future GMR use.

%M12257 (Continue)

When the application program has computed valid outputs that can be sent to output blocks, the application program must set control bit %M12257 (CONTINUE) to 1. When this is done, outputs to the blocks are enabled.
