 Hi,

Sam-J

Communication are healthy but i am trying to make program using RDREC but not successful. 

 what is the "STATUS" for RDREC?

To receive the correct status, please also have a look at following FAQ.

Furthermore, please post a screenshot of the RDREC instance.

How do you evaluate the status of system blocks in STEP 7 (TIA Portal)?
