Post by fajean on Issues with "Add all instance path" ^{CODESYS Forge talk (Post)}
In the past, we have routinely used the "add all instance paths" function to automatically add variables to VAR_CONFIG lists. My recollection is that compiling a project did not require VAR_CONFIG to be fully populated, and, once successfully compiled, instance paths could be added. Errors related to missing declarations, if I recall correctly, were thrown when downloading to the PLC, they did not prevent a successful compile. At some point, it stopped working. Missing declarations in a VAR_CONFIG now cause a compile error, so the application is never "current", the only reason I can see being the missing VAR_CONFIG declarations themselves (no other error). We observe the same behavior across all our projects. This is really aggravating, and I must be missing something simple. We use 3.5 SP17p3, 64 bits. Can anyone help?

IF you create an ENUM {attribute 'qualified_only'} {attribute 'strict'} TYPE E_IO : ( FIRST := 0, SECOND := 1 ); END_TYPE You should be able to access the array items like: IOCard_OUTPUT[E_IO.FIRST]

Post by ellcap on Symbol Configuration, I'm doing it wrong ^{CODESYS Forge talk (Post)}
if you're here because you are making the same mistake as me, I just resolved it. I mistakenly thought I didn't need to write the word attribute in the column labeled attribute. changed this 'symbol' := 'read' to this attribute 'symbol' := 'read' The last two in this clip are still wrong: I recongize this is probably a big "duh". That's ok. I like to fail out loud in hopes it helps someone else from looking silly.

Post by renezw on Access to a running Codesys instance via Python ^{CODESYS Forge talk (Post)}
I have a Codesys environment running and would like to inject code into the running environment at the same time using a code generator with Python via the console. So far I can only start a new Codesys instance with Python, but not access an already running one. How can I access the running Codesys instance?

Hi, you can program your path using 3 MC_MoveLinearAbsolute and blending mode TMCornerDistance. How to execute a movement: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_creating_an_axis_group_program.html Information on blending: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_robotics_blending.html Does this help you?
