Using Ladder In Iec Udfbs


Recommended Posts



I have found that when creating UDFBs in CScape 9.7 and IEC61131, there appear to be greater limitations on the use of functions in ladder than in Scripted Text.

When using a scaling block in a UDFB using ladder, it would not work, but when using a scaling block in Scripted text in a UDFB, the scaling block does work.

This has also been found using other function blocks inside a UDFB.


Best regards,
