Shortly said.. the block type is an interfacing to the timer that has as much possible functionality. The block type includes also the timer coil. The timer coil by itself does not have the same functionality as the block type. To make this more clear, please review the attached picture. w Attachment Visual clue_IEC timers_block type vs coil type.jpg (403 Downloads)

Now in later TIA versions it goes more about history than anything else. ..please do not start a petition to rid TIA of the coils [smile] I rather like using them. Regularly I use TONR timer coils that are reset elsewhere. The coding looks more clean in this way. Also think about it.. The coil type takes up less memory space and execute more quickly. You only use the elements you want when you need it. The block type vs coil type really comes down to designer's choice. Personally I use both of them.. depending on the code structure needed. Structure is important.. it should have a "story" to tell. As designer you should not struggle to make out your "hand writing", when you return to your coding in months from now. I can write a thesis on the subject of coding structure.. but for now take my word on it - coding structure is as important as documentation. Good programmers do both well. Sorry for straying off topic.. but hopefully your question is answered. w
