Step7

[wglespaul]

Thanks to everyone who've replied so far, its been a great help
Could anyone give me a simple explanation of the different types of blocks in step7 and their role in the organisation of a program.

e.g. OB1 -calling function, FB, etc..

Paul,

I think it's time that you take some S7 manuals and start reading. Try this Link.

Good luck
