A
Hardware logic control flag (X4)
While the hardware logic operates, Hardware logic control flag (X4) is on.
■
ON of Hardware logic control flag (X4)
In the following status, this signal turns on.
• When Hardware logic control start request (Y4) is turned on
• When the hardware logic control start request is issued with the configuration tool
■
OFF of Hardware logic control flag (X4)
In the following status, this signal turns off.
• When the power supply is turned on
• When the CPU module is reset
• When Hardware logic control stop request (Y5) is turned on (If Hardware logic control start request (Y4) and Hardware logic
control stop request (Y5) are turned on at the same time, Hardware logic control stop request (Y5) takes priority and
Hardware logic control flag (X4) does not turn on.)
• When the hardware logic control stop request is issued with the configuration tool
• From when the "Write to Module (execution memory)" or "Write to Module (exe flash ROM)" is executed with the
configuration tool until the hardware logic control restarts
• When the simulation is executed with the configuration tool
• When Hardware logic control stop flag at disconnection (X7) turns on
• When a stop error occurs in the CPU module
