I am using CPU 1212C with SIMATIC STEP 7 Basic Version 10.5. I am dumping data which is being acquired by the CPU into a DB say DB1. This data is different everytime with respect to the number of variables. For eg. One time it can be 30 bool, 40 Bytes etc or it can be 22 Bytes with no bools. Bottom line the data can be anything. Now I want to know is there any in-built function to calculate the number of these variables in the DB? If not is there anyway for me to find out the number? Hoping to get a quick reply. Thanks.
