Operation when fast logic output is off
■When fast logic interlock is enabled
When all the corresponding output signal points are turned off by the fast logic function, the fast logic READY (SA\XC) is
turned off, the fast logic function stops operating, and the fast logic interlock state is entered.
When restarting the fast logic function, turning off and on the fast logic initial request flag (SA\Y8) and fast logic start flag
(SA\Y9), or operating the reset signal X7 and start signal X6 causes fast logic READY (SA\XC) to turn ON and the operation
to resume.
The operation when the fast logic pattern setting is Pattern 2 is shown below.

Executed by the program
(1) When the fast logic output is not off, even if the fast logic initial request flag (SA\Y8) and fast logic start flag (SA\Y9) are operated, the fast logic initial
completion flag (SA/XD) does not change.
(2) Turning off and on the fast logic initial request flag (SA\Y8) when fast logic output is off causes fast logic initial processing to be performed. When initial
processing is completed, the fast logic initial completion flag (SA\XD) turns ON.
(3) When the fast logic start flag (SA\Y9) is turned off and on while the fast logic initial completion flag (SA\XD) is on, fast logic READY (SA\XC) turns on, fast
logic initial completion flag (SA\XD) turns off, and the fast logic function is enabled.
The operation of the fast logic function can be resumed by operating reset signal X7 and start signal X6 only
when the fast logic function stops operating during safety communications return (fast logic interlock state).
After safety communications changes from disconnected to connected, operate the fast logic initial request
flag (SA\Y8) and fast logic start flag (SA\Y9) to restart the fast logic function.
