DATERD and comparisons.   That instruction breaks the clock data into 7 registers, easy to work with.

I don't see this DATERD instruction. Is this new?

Is looks like the DtToDateStruct instruction does this.

This only works with the DATETIME data type as an input.  But yes, it will do this.

Might have gotten my wires crossed and be thinking of a different PLC..
