Appendix 1 Safety Remote I/O Signals
131
A
Fast logic READY
■
Device number
■ Description
This flag indicates that the fast logic function is in the enabled state. The ON/OFF state of the fast logic function is indicated.
This signal turns ON when all the following conditions are met.
• In safety drive mode
• When "Fast logic pattern setting" is set to anything other than "0: Not used"
• When fast logic initial request flag (SA\Y8) is operated
• When fast logic initial completion flag (SA\XD) is operated
• When fast logic start flag (SA\Y9) is operated
Fast logic initial completion flag
■
Device number
■
Description
This operation flag starts the fast logic function.
Turning on and off the fast logic initial request flag (SA\Y8) in the safety drive mode turns on the fast logic initial completion
flag (SA\XD). After that, turning on and off the fast logic start flag (SA\Y9) turns off the fast logic initial completion flag (SA\XD),
turns on the fast logic READY (SA\XC), and enables the fast logic function of the safety remote I/O module.
External output monitor
■ Device number
■
Description
These signals indicate the ON/OFF state of the external output signals (Y  ).
The state of the fast logic output can be monitored by monitoring the external output signal (Y  ).
Do not use external output monitor Y

in a program that operates safety functions. If the signal is used, the correct operation
of the safety remote I/O module safety functions is not guaranteed.
