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.

The product has two contact inputs available to detect the contact input signal.
This allows reading and monitoring the contact signal from an external switch.
If abnormality is detected in an external switch, this can activate an alarm.
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.
