that when the timer is a coil, if i insert it like a coil i don't get the question :'single instance" or 'multi instance' .
...

 Yes I can confirm your observation. That can be "helpful" if you declared a few timers inside the FB already and you do not want to be pested by the pop-up.

if i type in the letter d. i can only get the option for my global data blocks.   i dont get it done like a box timer if i choose single instance, than i get "iec timer under system blocks.

strange,  but ,  iam experimenting in fb2, when i type in a 'd' ,  i can also choose to for a instance db which belongs to fb1. but than that name above my coil timer remains red

-in my test program i created some timers and stuff, tested it with plcsim.  and i monitored everything including my multi instance data block. in your explanation part 2/3 you also talk about ; ET, PT, Q etc. but there is also something like ST. (it's properly system time of something maybe not important).  but i noticed it before that things like that remain stored in db and i wonder how i can reset tem in a db

that system manual of the plc where can i find it. perhaps are there also tutorials available for tia13 

that array thing you explained me.  i experimented with it,  and i came to the conclusion that the only advantage of using an array in this way is that it can cut down programming time, or it organizes memory, in some way. look at my screenshot and you see my version. 

but my problem initialy came from the next manual,  if you google it "working with siemens step 7" 

for so far ik look at it,   that timer thing can not be done exactly the same in tia13 as in step7 v5.5.  i must create datablocks that come with the iec timer. 

and if you open the tutorial and go to page 92. on that page is show how you can create multiple instances of a fb, this in order to save datablock. i've tried al lot but i can't get it done. can you show me.

Hi Gerard,

I have hoped that with all the talk you would have figured out by yourself how to solve your own question. The trouble is not Step7 V5.5 vs Step7 V13.0, but rather S7-300 vs S7-1200. The S7-1200 breaks away from some of the concepts used in S7-300.

There is nothing wrong with your opinion about the arrayed timers.. I am glad to see that you could reproduce it.

The S7-1200 System Manual can be found at [LINK].

Greetings.
