4.10 Through Function
With the GT series, communication can be set to take place automatically between the
COM. and TOOL ports in a “through function”. When the FP series tool software
installed in the computer connected to the GT series as shown below is booted, PLC
programs can be edited through the GT series.
The through function does not require any special settings, and is always in the standby
mode.

CAUTION
Precautions when using the through function
The system should be set up so that the interval for communication
retries in the FP series software (FPWIN Pro or FPWIN GR) (A) is
larger than that of the GT10 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.
Restrictions on COM. port connections
If the GT series is connected to the COM. port of the PLC, please be
aware that some functions cannot be used, such as rewriting in the
RUN mode in FPWIN Pro or FPWIN GR.
Precautions when connecting the FP Programmer II to the TOOL
port
If the FP Programmer II is connected to the TOOL port of the GT
series, the operating voltage of the GT series should be set to 25V
DC or less. Also, the GT series should not be left connected to the
