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.
