Hello,
I use CODESYS V3.5 SP7 Patch 3

I've got 2 visualization problems.

1°) First problem :
I drew a SFc Module called SFC1. The initial step is called Init.
I then use the 'Generate SFC Visualization' command. I got a visualization called SFC1_SFC_VISU.
When I look at how the first step is animated I found :
{implicit on} SFC1.SFCCurrentStep = '' OR SFC1.SFCCurrentStep = 'Init' {implicit off}
And for the animation of the transition :
{implicit on} SFC1.Init__to__Step0{implicit off}
It works well.

But if my firts setp (the initial one) is not called Init, but ST0 for example :

For the animation of this first step we have :
{implicit on} SFC1.SFCCurrentStep = 'ST0' {implicit off}The test blank value does not exist.
So when I start the controller that first step does not change color.
If I manually added "SFC1.SFCCurrentStep = '' OR " it works.

And for the animation of the transition :
{implicit on} SFC1.Init__to__Step0{implicit off}The name of the step does not change in the expression !

2°) Second problem
Even if I use sep name Init, Step 0, Step1 for a little sfc test.
When I transfert the project into the PLC (I use CODESYS Control ...) I get 1 error for each tranisiton :
Invalid expressions {implicit on} Grafcet1.Init__to__Step0{implicit off} configured ; Invalid expression
Invalid expressions {implicit on} Grafcet1.Step0__to__Step1{implicit off} configured ; Invalid expression
Invalid expressions {implicit on} Grafcet1.Step1__to__Init{implicit off} configured ; Invalid expressionI can run my program, but none changes color when the SFC is changing.

Thank you in advance for your answers.
Best regard

Hello Joel,

I faced same Problem. Just enable in the properties of your SFC the SFCCurrentStep and it will work!

Hello Ralph
I am glad for your answer !
You're right, it works better, but a small problem persists :
Instead of : {implicit on} SFC1.SFCCurrentStep = '' OR SFC1.SFCCurrentStep = 'ST0' {implicit off}
I get : {implicit on} SFC1.SFCCurrentStep = 'ST0' {implicit off} The test blank value still does not exist, and this step is not coloured at the start of the PLC.

But everything else works well.

Bests regards
