CTBL and IR problems.

[andreas_ 0]

Hello! I'm a complete beginner with plc programming so please bare with me! I have only done c/c++ programming before. :) Is it possible to create several comparision tables with CTBL? I'm trying to cut a pipe in a certain angle and I would like to have 1000 values in one table, but since this isn't possible I though I would create a new one when all values in the first have been found. Or does this somehow affect the high speed counter value? I think it should be possible. But I don't seem to be able to change the IR values inside the interupt. I'm including a my program below any advice or thoughts highly appreciated!!

Hi andreas, you can change the comparison table without affecting the counter value. The table is registered each time CTBL is executed. Since you only need to change it after a certain number of times, it is recommended to use the differentiated version (@CTBL) or a condition that is On for one scan only each time you want to change the table.

you even have to use it differentiated all the time (@CTBL) If not you run into problems (I had them once some years ago on CQM1H)
