Here is the description of the problem,
I have CNC Mitsubishi C64T and I am trying to connect GX Developer(8.20W) to it though ethernet cable. C64T is not connected to anything else so basically I have just two units, one is my laptop another is the C64T.
My laptop with GX Developer has the following manually configures network parameters:
IP address 192.168.1.1
Mask: 255.255.255.0
Gateway: empty

C64T has parameters set to default:
IP address: 192.168.1.2
Mask: 255.255.255.0
Gateway: 0.0.0.0

When I run command from my laptop "ping 192.162.1.2" it finishes seccessfuly.
Next step, I open GX Developer and select PLC Series: QnACPU, PLC Type: Q4A, Programm type: Ladder

Then I go "Online" -> "Transfer setup" menu, where I pick (see Attachment)
PC side I/F: Ethernet board (GxDev shows Network No. 1 Station No. 1)
PLC side I/F: Ethernet module
I double click on the Ethernet module picture and in the window with option I choose:
PLC: AJ71QE71 (I am not sure about this chice, the other option is QJ71E71)
Network No. 1 (is grey so I cannot change it)
Station No. 1 (is it really1? laptop has the same sation number too)
IP address 192.168.1.2
Routing param. Automatic response system
Save this.

Other station is set as Other station(single network)
Network route is set as Ethernet (Network No. 1 Statation No. 1)

When I click "Connection test" I get an error:

"Cannot communicate with the PLC. Execute again after cheking connections with the PLC. <ES:01808301>"

Same thing if I for PLC I/F set Station No. 2

If I try to change PLC from AJ71QE71 to QJ71E71 I get this error:

"An unusable port ot IP address is specified. Execute again after cheking the
port/IP address setting. <ES:01808008>"

So what do I do wrong that I cannot connect to the C64T?
