■11. When connecting to Built-in Ethernet port of Built-in Ethernet port CPU
Connect to GOT after turning on the network equipment such as Built-in Ethernet port CPU or HUB to enable the
communication.
When the communication with Built-in Ethernet port CPU is not available, a communication error may occur on the
GOT.
■12. The number of connectable CPUs for one GOT
QCPU:128 CPUs can be set (10 or less CPUs are recommended)
FXCPU:128 CPUs can be set (10 or less CPUs are recommended)
■13. Connection to RnSFCPU
The RnSFCPU takes 10 seconds or more to run.
If the GOT is started before the RnSFCPU runs, a system alarm occurs.
To prevent a system alarm from occurring, adjust the title display time in the [GOT Setup] dialog.

■14. Connecting to PERIPHERAL I/F
The GOT cannot be Monitoring other station. Routing parameter setting is invalid.
■15. When connecting the built-in Ethernet port of QnUD(P)VCPU using "MELSOFT
Connection Extended Setting"
When the port No. is set to [5001] using "Communication detail settings"-"Ethernet setting" from GT Designer3, it is
possible to access the built-in Ethernet port of QnUD(P)VCPU using "MELSOFT Connection Extended Setting".
However, the GOT may not access the PLC depending on the system configuration.
Examples of system configurations that the GOT cannot access and the counter measures are as follows.
(1) System configuration example 1
When connecting via the CPU No. whose "MELSOFT Connection Extended Setting" is set to "Use", the GOT cannot
access the other CPU No. whose "MELSOFT Connection Extended Setting" is set to "Not use" or CPU No. which
does not support "MELSOFT Connection Extended Setting".
(a) System configuration figure
"MELSOFT Connection Extended Setting": "Use"
1) Counter measures
Take one of the following counter measures.
• Change "MELSOFT Connection Extended Setting" at the PLC side.
Set "MELSOFT Connection Extended Setting" to "Use" in the CPU module No. 2 whose "MELSOFT
Connection Extended Setting" is available.
➠
• Change "Ethernet setting" at the GOT side.
Set the port No. of the connected equipment to [5006] by "Ethernet setting" at the GOT side.
