S7 Read_Clk how do I pull all 8 bytes into DataBlock? 2

I am finshing a project but need to parse out the DateTime from the Read_CLK SFC1. Can I just call the SFC1 and place the CDT result in a datablock?

Do it right or don't do it at all.

Good, now....how do I do it. I am missing something becasue I just can't seem to get things right. I tried the direct method by calling SFC1 and putting the results into DB9 but the types are different or something.

Is there an easy way to do this?

Hi,
a bit late but,

create a temp-var Typ DT e.g. #tmp_DT;
and then:

CALL "READ_CLK"
RET_VAL:=MW200
CDT :=#tmp_DT

CALL "BLKMOV"
SRCBLK :=#tmp_DT
RET_VAL:=MW200
DSTBLK :=P#M 300.0 BYTE 8

to transfer the DT e.g. to--> MB300 - MB307

Rolf,

That's it! Thanks. It is simple once you figure it out, hehe.

I am learning that I need to learn the Standard blocks to see what all tools are in there. I was looking for the Block Move myself.

Now I just have to be able to take the 8 bytes and convert them to DT formate to Set the Clock and I am done.

Thanks again.

When I said "yes" I ment:

CALL "READ_CLK"
RET_VAL:=#iRetVal
CDT :=DB1.DT1

where DT1 is data of type DT defined in DB1.
