Continue safety communication (With output interlock)
■Output interlock
In the following cases, the outputs are interlocked.
• Module operation mode is switched from standby mode to safety operation mode.
• Safety outputs are turned off due to an external power supply voltage error detection.
If the outputs are interlocked, the safety output control stops and the output signals (Y) are turned off.
The safety output control does not start until the safety output interlock is canceled by the CPU module. This prevents an
incorrect output before completion of checking safety in the working area and an incorrect output due to unintended recovery
of the external power supply.
