Hello all,
need help with Wago 750-852, cant connect with him over Codesys 2.3.
So i manage to ping him and i manage to open it over wago ethernet application.
And it shows this for 750-852:
IP: 10.112.22.182
subnet mask: 255.255.252.0
Gateway: 10.112.20.254
(S)NTP-Server 0.0.0.0
DNS-Server 1: 10.112.20.254
DNS-Server 2: 8.8.8.8

Codesys port 2455 is ticket and enabled in option
My PC IP: 10.112.22.100
My PC subnet mask: 255.255.252.0
Nothing is on network except 750-852 and my PC, and i can ping him, check all the data on web browser or with wago ethernet application, also i can change all but when i go inside CodeSys 2.3 and chose 750-852 and set connection to his ip 10.112.22.182, port 2455 and then try to connect i mean go online, Codesys status interface below say Code size, data, 0 errors, 0 Warnings etc. and then he throw popup window: Communication Error(#0): Logout Preformed.
Then i try to open if i can from 750-852 by pressing “File”-“Open”-then “PLC…” to open it from PLC. Again i chose 750-852 as a type and make a same connection type as above with IP, port 2455 for 750-852 but same popup windows show.

I tried with my other PLC wago 750-8203 and with him i can do all of this things what i wrote above but when i want to do this with 750-852 i cant.

Also i set all the TCP/IP connection for 750-852 like this:
IP: 10.112.22.182
subnet mask: 255.255.252.0
Gateway: 0.0.0.0
(S)NTP-Server 0.0.0.0
DNS-Server 1: 0.0.0.0
DNS-Server 2: 0.0.0.0

And still same error. I don’t know what makes problem for connecting or i am missing something???
Check all the dipswitches and they are correct 2,3,5,6,8 = 10.112.22.182

Thanks in advance for help!

Have you tried to connect with Ethernet Settings?
Sometimes a factory reset fixes problems with the device (but you will lose your program and retained memory)

Thanks for replay! Yes like i mentioned above i tried Ethernet settings application what is provided from wago and i can connect/read/check/change all the hardware data, same if i use web browser i can read/check/change but when i want to do connection over Codesys he give me that error popup.
I don’t want to reset factory reset because this is only version of program i have and it is on that wago. I mean company on jobsite told me that this is wago with that program i am only trying to salvage it if it is possible but for now no luck.

Hello, Have you been able to solve the problem ?
The problem may be comming not from the PLC but from the Codesys Gateway.
In Codesys, go to “Online” then “Communication Parameters”,
Click on the button “gateway”, and change from “Local” to “TCP/IP”, in the address select localhost and port 1210.
From time to time I have to switch around to have the gateway work again.
