Hi everyone, I’m new to working with this type of wago plc model 750-8216, and I’m having some problems. I’ve done the factory reset process on the plc, and I’ve been able to find out what its default IP address is, but the problem is that I unchecked one (or maybe all) of the check boxes in the network tab and now even if I do a factory reset again, I can’t connect to the web server, the plc answers the request if I ping . But when I try to connect through the browser or Codesys, it doesn’t connect to that IP address. What can I do to see the website again? I don’t have a service cable, just an ethernet cable. Thank you very much for your help.
What if you set the mode switch to stop and press the tiny “RST”/“RESET” button for 10-12 seconds? The PLC should get 192.168.1.17.
Have you touched the DIP-switches?
Hi bjornidar
I put the plc in stop mode, pressed the RST button for 8-10 seconds, and the SYS led started blinking, then I tried to access the ip address and it doesn’t load (I did this operation before doing a power cycle and after doing a power cycle), I tried with that default IP, but with the wiresharp program I could verify that the plc address is 192.168.0.147, which before changing the check boxes, was the address where I could see the web server. I haven’t pressed any switches, only Run/stop/Reset switches, to change to stop mode.
Can you access it over SSH ?
If not, you better try loading a new firmware if you are locked out.
Load a firmware on a SD card, power up your PLC, it will boot from a fresh new firmware.
By default it is in DHCP, but you can set the default IP address (192.168.1.17) just as you already tried to.
In order to reset the PFC to it’s current FW default parameter you have to:
Press the RST button and at the same time put the RUN/STOP switch to RESET and keep both button until the SYS LED goes GREEN/RED blink, at this moment release both buttin. (you may need to do it more than once to have the timing right).
And wait for the PFC to reboot.
I tried that option but was unsuccessful, I can’t access via SHH. Thank you very much for that solution.
I performed this operation and after the reset I was able to access the web server again, I really appreciate the help given to everyone, you are a great community, thank you.
