1. Set communication error (AL34) and contact input signal detection.
・ Communication error (AL34)
The alarm “AL34: communication error” is activated if no request message from
the host computer arrives within the wait time during use of serial communication.
Operation at the time of alarm and message waiting time can be set.

Options to select “Continuous monitoring” or “Monitoring during operation” are
available. Also, the detection start time after the start of operation and the
detection end time can be set.
・ If the signal of “Contact input 1” is detected: the alarm “AL30: Detection of
contact input 1 signal” is activated.
・ If the signal of “Contact input 2” is detected: the alarm “AL31: Detection of
contact input 2 signal” is activated.
・ “Delay” time: sets the start time to detect the contact input signal after the
start of operation.
・ “Off detect” time: sets the time between the detection of the contact input
OFF signal and the activation of the alarm.
