The GT cannot communicate with PLC unless the target usage of the RS-
232C port is set to "Computer Link". Always set the setting on the PLC side
to match "Computer Link".
3.4.2 Through Function
GT series is equipped with the through function which passes the communication received
from the USB port for our PLC through the COM port.
When the tool software for the FP series/FP7 series is booted on a PC connected to the GT
series, PLC programs can be edited or monitored through the GT series.
The through function is always enabled when the PLC type for GT is set to Panasonic PLC.
It can be used in combination with Panasonic PLC equipped with an interface.
The system should be set up so that the Timeout period in the FP series
software (A) is larger than the waiting time for communication retries of the
GT COM port (B), meaning (A) > (B). If the system is set up so that A = B or
A < B, the through function will not work properly.
