Read DataBlock from S7-1200 To kepsver!?

hassanayoub85 · Jun 23, 2013

Dear,
I am trying from a long time to read the DB from S7-1200 To kepserver without any success.

Can you help me with a direct solution?

I use IX.Y, QX.Y, MX.Y to read input, output and memory tags.

But, I donno how to read DB.

Please help

It's only possible to read from DBs in abolute address mode, when the DB was initially created as S7-300/400 compatible.
This option cannot be changed on an existing DB, the dialog only appears when a new DB is created.

If you compile the S7-300/400 compatible DB, a column with the offset-address in the DB is shown. This is the address to access the variables in the DB.

The symbolic address mode of the 1200 is afaik only possible with the new TIA WinCC Basic panels.

if this is a global data block, copy it to excel, delete it, create a new one, and paste excel data. will speed up the transformation.

Thanks for answers.
I am using latest TIA version.
But after compiling, no aymbolic address is appearing.
Any help?

most interesting... sure that column with address is not hidden?

also check that block is not created with optimized access, but that would probably not be the case since you defined cpu as 300 series...

hassanayoub85 · Jul 3, 2013

Sorry, but what to try?

hassanayoub85 · Jul 3, 2013

All columns are shown, and there is no address column

balash · Jul 3, 2013

my guess would be the he pointed to data block -> properties -> general -> attributes -> optimized block access (cleared checkbox)

in the picture should be the last checkbox

EDIT: a-ha! there lies the problem(s)

1. why is offset unselected
2. why is offset greyed out (disabled)

balash · Jul 3, 2013

maybe, but that is really doubtfull since offset is dimmed, if you click show all colums?

hassanayoub85 · Jul 3, 2013

I removed the optimised access, and now offset column is appearing.
But no address column

JRW · Jul 3, 2013

Now compile and look again

balash · Jul 3, 2013

well then you solved your problem. my mistake, i replace offset with address.

EDIT:
yeah, ALWAYS compile after any change !!
