Setting up Wago PLC in Codesys and writing first program

 

1.      Make sure you have Wago Ethernet Setting, WAGO-IO-CHECK, Codesys V3.5 installed in the PC.

2.      Check your PC’s IP address by going to Control Panel àNetwork and Internet.

One can also check IP address using command prompt and typing “ipconfig”.

3.   Now open Wago Ethernet Settings and press “READ”. It will display the connected PLC if the controller IP address is in same segment.

4.      If the PLC is not detected, it may be due to improper LAN connection or different IP settings. One may use the Wago PLC programming cable (Wago 750-923 Service cable)  and Wago IO Check to set the PLC IP. Note that default IP address of Wago PFC200 controller is 192.168.1.17.

5               Open WAGO-IO-CHECK.

 6.      Go to SettingsàCommunication

7.      In the Communication setting window, choose suitable COM port (check Device Manager for knowing the COM port to which PLC is connected). Set the PLC IP address in same segment as PC using Network tab.

8.     I encountered problem when selecting Cockpit as Runtime System, so I selected Codesys V3. It worked for me.

9.      Now ping the PLC IP address using command prompt and it should reply. Also check using WAGO-IO-CHECK to identify the PLC and its modules.

10.  After successful ping and device identification, launch Codesys. Once Codesys is launched, create “New Project” à Standard Project and save it to a desired location in computer.

11.  Select suitable Target. If no PLC is connected and user want to run in Simulation mode, select “CODESYS Control Win V3” from the dropdown menu. I have 750-8212 connected.

12.  Then do a Gateway connectivity confirmation. Put PLC IP address if needed. When both the LEDs are green, it means connection is successful.

 13.  Since I have actual PLC connected, it is required to create a K-Bus. First do a hardware scan to detect the connected IO modules.

14.  The above error means the application must be logged in.

15.  After that scan for device and it should show the connected IO modules. Select “Copy All Devices to Project”.

16.  Once the devices are added to project, do K-Bus mapping.

17.  Write your first PLC program.

 

 

 

The steps followed may work even if after slight difference in sequence.
