TIA PORTAL ADAPTING S7-1200/1500 FB to S7-300

I have the Simatic Blocks Library from the ABB website to control their Drives they have Library for S7-300 (STL) and S71200/1500 (Ladder).

STL is difficult to understand therefore I wanted this block to be in Ladder therefore I decided to use the S7-1200/1500 FB and get rid of errors to make it adapted to S7-300 CPU

S7-1200/1500 TIA blocks in S7-300 had some errors on compiling .

IN 10+ networks the error is fixed by changing the command "Move" with BLKMOVE , because Move does not support Struct data .

Finally two faults are remaining Error in Network 74 and Error in the Last Network

Error in Network 74 :
I need to convert the Byte to INT but always positive i think because original data type was USint from 1500 and pass to the block which will then ADD 1 to it and then transfer back the value to BYTE some STL code to do this should take care of this before and after the block .

Error in the Last Network:
Fixed by changing the data type but skeptical if this can cause some issues

Have you downloaded FB500 from this link. (V1.3 ABB drive library for 3xx)?

Because it has only NW1 on STL and all the rest are on ladder.
NW1 is still quite easy STL.

Only moves and set / reset comparing


No need to convert from TIA to 3xx series...

Yes from here .
I was able to get the errors fixed but after compiling the ladder as written in s71200 and 1500 is also not compatible in S7-300
