Caution when transferring screen data to the F920GOT-K (5V type)

Caution on Start-up
• Never connect any cable other than a screen data transfer cable to the RS-232C port on the
F920GOT-K when transferring screen data. Otherwise, it may cause critical damage to the
F920GOT-K or connected equipment such as a PLC and personal computer.
• Do not connect the PLCs to the RS-232C port and RS-422 port on the F920GOT-K at the same
time. Otherwise, consequential effect or damage may be caused to the F920GOT-K or PLCs.
When transferring screen data, the F920GOT-K (5 V type) needs to be connected to the PLC in the
power ON status in order to supply power to the F920GOT-K (5 V type). (Connect the F920GOT-K (24 V
type) with a cable used also for the F930GOT and F940GOT.)
1) In the case of the FX/A/QnA Series PLC CPU direct connection
Connect the PLC to the RS-422 port.
When connecting the FX/A/QnA Series PLC, use the applicable RS-422 cables shown in the cable
diagrams in Chapter 8, 9, and 10 respectively.
A personal computer is to be connected to the RS-232C port via a screen data transfer cable.
2) In the case of the Q Series PLC CPU direct connection
In order to execute data transfer between a personal computer and the GOT, they should be
connected by a screen data transfer cable via RS-232C ports following the procedure below.
First, disconnect the data transfer cable between the Q Series PLC and the GOT. Second, connect
the data transfer cable. Third, connect the PLC and the RS-422 port on the F920GOT-K using the
power cable which is prepared by the user in reference to the cable diagram in Chapter 11. Then
execute data transfer using the screen data transfer cable.
a) When transferring screen data
- Turn off the PLC.
- Connect the RS-232C port on the GOT and the personal computer using the data transfer
cable.
- Connect the power cable to the RS-422 port.
Execute the transfer after selecting DATA TRANSFER on a system screen.
Once screen data transfer is finished, make sure to turn off the PLC and disconnect the power
cable before connecting the Q Series PLC to the RS-232C port of the GOT. Otherwise, it may
cause critical damage to the connected equipment such as the F920GOT-K, PLC, or personal
computer.
