Hello! Has anyone worked with a PCF200 purchased from CoDeSys (750-8212)? I have a customer that is using one. They updated the FW to FW27 (WAGO) and then back to FW11 (WAGO). Now the SYS led is flashing green at 1 Hz. Does anyone know the reason? A flashing green SYS led is not listed in the manual.  
BR, Mike Giroux

How was the FW updated, via SD card or WAGO Upload?

I think to go to 27 Upload was used. To go to 11, there is just an image file so an sd card was used. FW11 is what is loaded now.

As it turns out, this customer was trying to do more than what the controller can do. He wanted to program it using CoDeSys2.3, e!C AND CoDeSys3.5 without changing the FW version. He is contacting CoDeSys to get it back to their version.
