ILock Documentation Issue

[garysdickinson]

I got bored and decided to do some recreational PLC coding and decided to write a Tic Tac Toe program in ladder logic.  

To make the problem more challenging I decided to attempt to write the code without using custom functions, just 100% ladder logic.  

This is where I got into some issues with the [ILock] and [ILoff] functions.  Turns out that they are not broken, but I was transfixed by the example in section 9.3.5. of the TL6ReferenceManual.  

 [ILock] and [ILoff] turned out to not be very useful for my purposes, but I'd like to know how to program the "Equivalent Circuit".  I have tried everything, but I can't build this circuit with i-TRiLOGI 6 or 7.

Best regards,

Thanks Gary.

i-TRiLOGI can't produce the ladder logic graphically as shown on the equivalent circuit on the right.

By using [ILOCK] and [ILOFF] the logic on the left is equivalent to the logic on the right. Basically that's what it meant.

Oh damn.

The equivalent circuit seemed so much simpler than using ILock and IOff!
