START UP SOUND
Select the type of sound that is output when the GLC starts. If
BUZZER
is se-
lected, the GLC unit’s internal buzzer will be sound. If
SOUND
is selected, a
sound will output from the speaker connected to the GLC.
This section explains how to use the Retry command to deal with errors, including
those that occur during GLC and PLC communication.
RECEIVE TIMEOUT (1 to 127)
Use a numeric value to set a period of time in which the GLC receives data from
the PLC. If the cable is not connected, data communication will Timeout after one
second, regardless of this setting’s value.
The default value for the
RECEIVE TIMEOUT
setting is 10 seconds.
An error message may appear on your personal computer if:
•
You transfer screens from your PC to the GLC after a PLC
communication error has occurred and the error is not yet
cleared.
•
Your GLC unit’s RECEIVE TIMEOUT value is set to 30
seconds or more.
RETRY COUNT (0 to 255)
Use this setting item to designate the number of times the GLC tries to send data
to the PLC when a PLC communication error occurs. After the GLC unit’s speci-
fied number of attempts has failed to send data to the PLC, an error message will
appear on the GLC.
The default value for the Retry Count setting is
“2.”
