is it possible to insert a drop down or a wild card to a function block in tia portal provided PLC is siemens 1214 and software is TIA V15 as for example, in a "convert" instruction there will be an automatic drop down to select the data type of source and destination.(please refer the attachment) in such a way, is it possible to add drop down list to a user made function block ------------------------------------------------------------------------------------------ |

The closest thing that comes to mind is the use of "Variant" as a datatype. Inside the block, the plc checks the datatype of the provided parameter. If it matches a given datatype, it can then execute datatype specific logic, or set some flag to indicate the datatype for use elsewhere within the block. F1-Help on various "isxxxx" instructions, and how they can be used.

See attached zip. For some reason, I could not reliably post the png image inside the zip. It posted once, but when I hit preview, I lost it.
