8 FUNCTIONS
8.4 Safety Output
Fast logic interlock
When the output is turned off by the fast logic function, the output is interlocked. When the fast logic interlock state is entered,
the output signals (Y0/Y1) do not turn ON again unless there is a restart instruction, reset signal, or start signal input from the
CPU module. This prevents unintended fast logic restarts. For applications that do not require interlock, fast logic interlock can
be disabled.
■
Fast logic interlock state conditions
Under the following conditions, the output signals (Y0, Y1) of the fast logic function are turned OFF and the fast logic interlock
state is set.
• When the safety remote I/O module is disconnected from safety communications
• When the safety output enable signals (SA\Y0, SA\Y1) are turned on and off
• When the output conditions of the set logic pattern of the fast logic function are not satisfied
■ Resumption of output from fast logic interlock state
The method of restarting output from the fast logic interlock state differs depending on the conditions that caused the output
signals (Y0, Y1) of the fast logic function to turn on. For details, refer to the following.

Precautions
• When the fast logic interlock is disabled, it is customer's responsibility to build the interlock circuit externally so that the
entire system always operates safely. Be sure to connect an interlock mechanism to the output of this I/O module.
• If the measure to prevent the restart cannot be taken, take other measures and ensure that operators are safe and machine
parts are not damaged even if a device has restarted with the fast logic interlock disabled.
