Dear All Experts,

I am working for Drives nearly 6 years for Service and Commissioning of Drives,and I can Communicate and program with PLC . I can communicate, Check, Monitor,Understand the Step 7 program.

Its strange to ask that i dont know how to use DB and FB. I have very much confusion about using the FB, DB, UDT.

In short I dont understand concept of DB, FB, & data types that how to use in program. 

Can anyone give me simple way to learn or understand it.

Thanks in advance.
