Precautions
• To send S9F7 when the data received from the host is illogical, enable the S9F7 return relay setting.
• Detect S9F9 by notification of the T3 timer timeout.
• Detect S9F13 by notification of the T9 timer timeout. Note that a message needs to be created by the programmable
controller CPU since S9F13 is not automatically sent.
■When "S9Fx" and individual notification relays have been enabled
Ex.
When "S9Fx" and "S9F7" have been enabled
First, the S9Fx notification relay turns ON, and then the S9Fx notification relay is turned OFF by the programmable controller
CPU. Next, the S9F7 notification relay turns ON, and then the S9F7 notification relay is turned OFF by the programmable
controller CPU.
