Hello,

does anyone else have some issues with Debug/Flow control and variables declared as VAR_IN_OUT (at least in FBD view and LD view) ?

Declaration as follows:
FUNCTION_BLOCK TestFB
VAR_INPUT
Input1,Input2:BOOL;
END_VAR
VAR_OUTPUT
Output1:BOOL;
Output2:BOOL;
END_VAR
VAR
DelayON,DelayOFF:TON;
END_VAR
VAR_IN_OUT
IO_StartBit: BOOL;
END_VAR

In FBD view, it seems that the processed statements / variables are correctly displayed in a green Flow Control boxes, while the value of the variables itself remain ??? (Example in FBD_logic.png).

In LD view the same logic displays the Flow Control boxes in a network up tu the VAR_IN_OUT variable as green and then they become gray, while the inside of the status of the VAR_IN_OUT variable is green (Example in LD_logic.png). All this goes against the description of how Flow Control in the help files...or maybe I'm missing something ? (This does not depend on the actual value of the VAR_IN_OUT variable.)

The logical operations itself seem to be preformed correctly, just the Flow Control display seems wrong to say the least.
