Hi,

Here there are some tips to use SIMATIC NET 2008 to read DB variables of S7-1200 in OPC Scout:

1 – Don’t define the DB as “ Symbolic access only“

2 – If the OPC-Navigator doesn’t “browser” the DB variables, define then manually:

- Browser M variables

- Before return to the OPC Scout, mark the variable with mouse, right button, and click in Modify Item (see attached jpg)

- Change the address manually (e.g. from S7:[S7_connection_1]MB0 to S7:[S7_connection_1]DB1,B0)

------------------------------------------------------------------------------------------
Split from SIMATIC NET 2008, S7-1200, OPC Scout and DB variables.
