HI
In a previous post you made reference to a flip flip (motor on and off with one p/b) using an xor in s7 in FBD ?
Not being familiar with S7 FBD what exactly is this ? Reason for my question is i am just doing a little flip flop circuit on a Moeller Easy 800 and it has an xor function in Function Blocks, would this translate easily ? or not ? i seem to have a mental block on the scenario!!!
Whilst i can easily do it with ladder i thought it may make a change to try the xor if at all possible!

S7Guy said:Hey Johnny, I can't take credit for that. I can't remember who posted it originally, but it went like this:
A #PushButton
FP #AuxPB
X #PBStatus
= #PBStatus
It doesn't convert to S7 ladder, but it converts to S7 FBD.
