Compilation Warnings​

ALS RecipeCopy​

Investigation​

In network 3 both the source and destination recipe numbers are compared with the #START_RECIPE

// pseudo code
if sourceRecipeNumber < startRecipeNumber
 || destinationRecipe < startRecipeNumber:
    // by-pass write to `#"ALS RecipeCopy"` ,jump to `END` and set `#error`

The Fix​

At beginning of the function, added;

    L     0                    //<-- Added to resolve compilation warning. afl 121025
    T     #"ALS RecipeCopy"    //<-- Added to resolve compilation warning. afl 121025

RECIPE_COPY​

Investigation​

Similar findings as above with ALS RecipeCopy.

In network 1 both the source and destination recipe numbers are compared with 1

// pseudo code
if sourceRecipeNumber < startRecipeNumber
 || destinationRecipe < startRecipeNumber:
    // by-pass write to `#RecipeCopy` ,jump to `END` and set `#error`

The Fix​

In network 1 added the following;

 1    L     0                    //<-- added to resolved migration compilation warning. afl 121025
 2    T     #RECIPE_COPY         //<-- added to resolved migration compilation warning. afl 121025

SBL_WordToBits​

The Fix​

Cut the IN_WORD parameter from the blocks Input interface and pasted in the blocks InOut interface.

SELECTION_16​

The Fix​

In network 1 added the following;

 1    L     0                    //<-- added to resolved migration compilation warning. afl 121025
 2    T     #VALUE         //<-- added to resolved migration compilation warning. afl 121025

INTEGER TO S5TIME​

Investigation​

TIA Portal provides the T_CONV function which perform the INT to S5TIME conversion.

The Fix​

Therefore, deleted "INTEGER TO TIME" and replaced usage with T_CONV. Example shown below;

TREND_PENS_2​

Investigation​

TREND_PENS_2 called in GeneralHMI

The Fix​

Moved parameters PEN_x , where x is 1 to 6 inclusive, from the Input interface to the InOut interface.

COM_M_Alcip_FC​

Investigation​

img_1.png

Found the addresses were both occupied by the same UDT which is 16-bits wide

The Fix​

Therefore, updated with the symbolic tags. As shown below.

COMPLETE_RESTART​

Investigation​

Danfoss drives are not used in this project.

The Fix​

Deleted Network 1

_STD_CondEvaluation​

Investigation​

What's Next​

Investigating writing a new function in SCL and estimating work load.
