To connect the RCPU or QnUD(P)VCPU to the GOT by setting the network number and station number using project data transfer via the PLC or other methods, configure the MELSOFT connection extension settings with the engineering tool of the controller. 
When using the MELSOFT connection extension settings, match the network number and station number of the RCPU or QnUD(P)VCPU with those of the screen design software. 
The port number is 5001.
