Graphic Operation Terminal F930GOT
• In the case of CPU direct connection with the FX/A Series PLC, up to four GOTs can be
connected to one PLC (1:N connection).
Select "CPU PORT (RS-232C)" or "CPU PORT (RS-422)" as the connection type.
System configuration
FX/A Series
Communication via
RS-422
Maximum extension
distance: 30 m
Note:
A peripheral unit of the GOT or a peripheral unit to create sequence programs cannot be
used at the same time with the GOT except in the system configuration shown below using
the FX -422-BD in the FX
2N
nected at a time.
Connection cable examples:
1st GOT: FX-50DU-CAB0 (equivalent to connection cable for the PLC)
2nd GOT: FX-232CAB-1 (3 m)
3rd GOT: Cable created by user (Refer to the connection diagram.)
4th GOT: FX-232CAB-1 (3 m)
Communication speed:
The communication speed (= baud rate) with the PLC becomes slower as the number of
GOTs increases.
When the communication speed in the first GOT is supposed as "1",
2nd GOT: Communication speed in the 1st GOT × 2 (= 1/2 of that in the 1st GOT)
3rd GOT: Communication speed in the 2nd GOT × 2 (= 1/4 of that in the 1st GOT)
4th GOT: Communication speed in the 3rd GOT × 2 (= 1/8 of that in the 1st GOT)
• In the FX
