GP-477R/577R Series User's Manual 5-13

• With the GP-577RS series unit, reducing the display brightness may cause

flicker. Adjust it by changing the display device settings.

5. "DISPLAY DEVICE SETTINGS"

• To end BRIGHTNESS ADJUSTMENT mode, press anywhere outside the

bottom of the screen.

• BRIGHTNESS ADJUSTMENT mode cannot be entered while waiting for

GP to start up.

• BRIGHTNESS ADJUSTMENTs can be made even during RUN mode

(PLC<—>GP communication).

RECEIVE TIMEOUT

Set up how long the GP unit will wait when there is nothing being sent to it.

(This is the Timeout Time.) However, if there is no cable connected up, then

regardless of the time set up here, the Timeout value is 1 second. The

default value is 10 seconds.

• When a value of over 30 seconds is set here, and a screen is transferred

from the PC while a PLC Communication Time error has occurred, an

error may also appear on the PC side.

RETRY COUNT

Set up the number of times the GP will try to send data when a Communica-

tion error occurs. Even if the data is resent, unless the transfer is successful,

an error message will be displayed on the GP.

These fields set when an error message is reported after a GP<—>PLC

communication error is detected. This ensures an error has actually taken

place and not just slight breaks in communication or slowness in processing

data on one side or the other.
