Hello all!

I am posting regarding following issue, hopefully you could provide me some support regarding that or maybe you have experienced something similar?

We are using WAGO PFC200 PLC (750-8216 unit; PFC200V3-43BBCF) in our products and quite often we are facing issue with downloading the new software to PLC using CODESYS V3.5 SP13 Patch 1 + (32-bit) (target version: 3.5.13.20).
WAGO PFC200 PLC 750-8216 unit is connected to the test PC through Welotec FTK815L-EX0 router using X1 Ethernet port.

Steps to re-produce the issue:

1) WAGO PFC200 PLC is in run mode (running previously loaded application)
2) Project -> Clean all
3) Go to Device (CODESYS Control for PFC200 SL) -> Scan network… -> click on the PLC in the list
4) Online -> Login
5) Pressing "Yes" on tab "Application 'Application' does not exist on device 'Device'. Do you want to create it and proceed with download?"
6) Waiting for some time and following error appears in different tab: "No connection to the device. Please rescan your network."
7) If above error happens it is not possible to find PLC using the CODESYS Scan network… option. However it is possible to ping it OR find out that the previously used IP address is still in use (by using for example Advanced IP Scanner). It seems that also the RUN LED on WAGO 750-8212 unit remains RED after that happens.
8 ) Only way to be able to find (see) PLC again using CODESYS Scan network… option is to reset PFC200 locally by using the button on PLC (by changing it from RUN -> RESET -> RUN mode).

Thank you in advance
