Hi we have bought an AXL SE RS232 and connected to a PLCnext sarter kit (2152 controller), I wa adviced to use PLCnext Store | AXL_ComSerial library and AXL_RSUNI_PD block in FBD to read.

I tried downloading the library from the PLCnext store and added it to:
C:\Program Files\PHOENIX CONTACT\PLCnext Engineer 2025.0\Libraries

but cant find it in PLCnext Engineer, have I missed something:

Unfortunately the process is not very intuitive, but it involves two steps:

  1. Installing the library on the file system.
  2. Moving (or copying) the .pcwlx file to the location that PLCnext Engineer expects to see it.

  • It looks like you’ve completed the first step. To complete the second step:
    Open PLCnext Engineer and select „Add User Library…“ from the „Libraries“ shortcut menu, shown below:
  • When the file selection window opens, it will show the path to the place where PLCnext Engineer expects to find library files. You should move (or copy) the .pcwlx file to that folder.
  • You should then be able to select the library and add it to your project.

Hi Martin,
Did step 2 and step 1 (which I have done before involved moving the same file tight .pcwlx to C:\Program Files\PHOENIX CONTACT\PLCnext Engineer 2025.0\Libraries)

But I am still unable to find the FBD inside PLC next Engineer.

What path do you see in the file selection window when you right-click on „Libraries“ and select „Add User Library …“ ?
Here is the path I see:
image.pngThe list of files shown in the window includes all the PLCnext Engineer libraries that I have installed and moved (or copied) to that folder. All you need to do is move (or copy) the .pcwlx file to that folder, then you can select it and it will be included in your project.

Yes it was the path, that was sorted, thanks.

My application requires the PLC to always look for Serial inputs and turn on Digital output for 1.5 seconds ones it get a serial message and save the message to a string which will then be published over mqtt (haven’t done mqtt part yet):
image.pngIn the above FBD I have to turn on „xRecieve“ each time when sending data over serial, is there a way to always keep looking for messages (Eg: every 50ms), would a TP (I understand this as a pulse) help?
