Which programme should I use to connect to a PLC with these specifications? I couldn’t find the WAGO library in Codesys 2.3 e cockpit tamamen kaldırılmış I need to update the firmware for Codesys 3.5, but I’m getting an error there too. ![Ekran görüntüsü 2026-08-04 170541](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/0/0cb0105cd72f4968e9282524226ffa37f48daa36.png) ![Ekran görüntüsü 2026-08-04 160029](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/e/e5677fe289af78394c94cca2073841f7c13e4203.png) ---

Hi, If I remember correctly firmware version 12 is the first version for using the upload tool. You need to update by sd card. For the 8202 controller firmware 22 should be the last revision. > **[Release Firmware 22 (v03.10.08) · WAGO/pfc-firmware](https://github.com/WAGO/pfc-firmware/releases/tag/v03.10.08-22)** > > Added img files. e!cockpit ist required for programming. Normal codesys 3.5 is not supported. ---

e!COCKPIT is a commercial product that is no longer supported. To keep using CODESYS V2.3 or move to V3.5, you must purchase the CODESYS runtime for the PFC200 directly from CODESYS, not WAGO. Alternatively, you can use model 8212. ---

Where can I find the Codesys v2.3 library for the 8202 PLC? ---

Please contact your local WAGO Support office. We are not allowed to post links to Codesys 2.3 target files here. ---

If you are planning to use this hardware in new project - don’t. Buy 2gen PLC and use CODESYS 3.5
