Set these parameters to the same conditions as the PLC.
Note Reset the EJ1 to enable settings.

Adjusting
Communications
Time with PLC
With programless communications, the time from when the command is sent
to the PLC until a response is returned is monitored using the Programless
Communications Receive Wait Time.
• This time will differ, depending on the PLC cycle time. Consider the PLC
system configuration and allow sufficient margin when setting the
response wait time. Communications will not be normal if this setting is
too short.
Note Reset the EJ1 to enable settings.
This parameter is not valid when an NT Link is being used.
