Reading Data from S7 PLC

[jacaré]

Do changes have to be made to the Siemens controller for this? Is it also possible to read data from data blocks with optimized block access? If I remember correctly I can access here then no longer with DBXX.DBBXX.

Is this then this variant?

Hello,

Kindly share the snap version installed

Reading from data blocks is absolutely possible provided the optimized block access is turned off in the PLC Project

Thanks

Hello,

we are currently working on an offer for one of our Customers. Therefor we do not have a installed Version yet.

So is it not possible to access the data blocks if the optimized access is turned on?
Is there any other option access the date without changes on the PLCs?

Hello,

No we cannot access if the Optimized is turned on as the same won't have any fixed offset addresses.
Rather Standard block access will put all the variables into one data block by creating offsets for the same, So the variables can be read using that address

Hope this clarifies.

Thanks
