I pinpointed down 4 possible causes for this compiler error: Bare/empty statements (;) standing alone inside an IF/CASE branch — just removed two instances. The optimizer that tries to inline/replace expression statements may choke when a statement has no actual assignment to extract. A VAR_IN_OUT parameter used directly as a FOR loop's own control variable (FOR X := X TO Y DO) General deep-nesting complexity — every one of my decode routines has the same shape (IF busy THEN ... FOR loop containing...

Internal compiler error in SP22.x (expLValue null) — SP21 unaffected — need help isolating root cause I'm hitting the same internal compiler crash reported here. Same exact stack trace (AssignmentStatementReplacer → CreateAssignmentExpression → ArgumentNullException: Value cannot be null. Parameter name: expLValue), but in my case triggered by a self-written library, not a Visualization object — so this looks like a general SP22.x codegen regression rather than something tied to one specific language...

Now I understand. I always thought this was not supported. I might test it later. Thanks.

I ran into this issue as well. Here is the fix: Good example: CASE iBitmap OF 0 : sName := 'ImagePool.image0'; 1 : sName := 'ImagePool.image1'; END_CASE Bad example (this will only work on the target device, WebVisu will show a blank rectangle): CASE iBitmap OF 0 : sName := '/home/cds-apps/PlcLogic/visu/image0.png'; 1 : sName := '/home/cds-apps/PlcLogic/visu/image1.png'; END_CASE

I installed Linux ARM SL and it recognizes the RJ45 ethernet ports, but I cannot get it to recognize the internal port for the IO cards.

Hello, Is it possible to check if PLC application is running or stopped from linux shell? I am using codesys control for linux arm64sl. Tried accessing the plc shell, but get auth errors. Also, when starting/stopping the program via plc shell from codesys IDE it doesnt report that information to log
