Title: How can you input this ladder structure?
Post by: Joel Moore on February 11, 2004, 09:01:01 AM

In the triloghelp.pdf file in the section discussing the interlock function you show an equivalent circuit that can be replaced by the interlock functions.   It looks similar to this:

Code: [Select]

----| |----------| |------------------( )
                                           |
                                           `----| |------------------( )
                                           |
                                           `----| |------------------( )

But I can't for the life of me figure out how to create that.   Is it even possible in TRiLOGI to do this?

TRiLOGI editor can't create parallel branches as shown in your drawing. That's why the [ILock] and [ILend] special functions are used to implement what's equivlalent to the parallel branches.

The manual actual describes what [ILock] and [ILend] is trying to achieve. It didn't mean that TRiLOGI can actually create the parallel branches.
