6.4.4 COMMUNICATION SETUP

RECEIVE TIMEOUT (1 to 127)

Sets the value used for the data reception timeout (PLC <--> GP).

If the cable is not connected, data communication will Timeout after one second,

regardless of this setting's value. The default is "10" seconds.

RETRY COUNT (0 to 255)

communication error occurs. An Error Message will appear on the GP after the GP

tries to send data to the PLC the number of times set by this option. The default is

"2".

An error message may appear on your personal computer if:

• You transfer screens from your PC to the GP after a PLC communication

error has occurred and the error is not yet cleared.

• Your GP's RECEIVE TIMEOUT value is set to 30 seconds or more.

The following explains the use the of the retry command to deal with errors,

including those that occur during GP and PLC communication.
