Combined EQ OR

[Johan Beijer]

Hi, are there any combined EQ and OR block for GX IEC Developer and the FX3U plc? For example instead of doing this: I would like to do something like this:

No. Hope, you understand that with the logic block, shown on the second picture, the value of Test_Out signal will be FALSE always.

Ok, thanks for the help. Yes I understand that it will always be false. I might try to do a Function or a function block on my own then with a fixed amount of legs instead. A follow up question on that, Is it possible to make your own blocks that you can extend the amount of legs on by dragging the bottom. For example one of the standard functions "EQ_E" got a input class called "var_in_ext" but I can't find it when making my own functions.

Sorry, the answer onto your second question will be negative too. The possibility of expanding the FB, dragging of its bottom, is available for FBs from the manufacturer library, not for the users. The same applies to type of variables, which list is wider for the manufacturer's purposes and restricted for the usage of user. But it is not surprising, the software developer always know, what he want to realize, but never can give the same universality for user, because he don't know, what functional block the user will design and what will be the input and output variables of such FB.

Ok, thanks. I really appreciate all the help even though I was not able to do what I wanted it made it all more clear and I can continue programming.
