What commands are you not familiar with? If its the (SD) and (SF) then they are just On-Delay timers and Off-Delay timers respectively.
I think the issue must be one that was highlighted by LD a few posts back where there's a problem putting a parallel connection into a rung with multiple output coils?
If it was me I would put all the first set of conditions ie:
Code:
A CycleRunning
A(
O Passed
O Failed
O CancelCycle
O M5.0
O ESR
)
ON CycleRunning
A(
AN AutoMan
A Cylinder4FailUp
O CancelCycle
O M5.0
O ESR
)
... to a spare marker bit (for example M100.0).
Then use that marker bit in a separate network like the following:
Code:
A M100.0
O *** YOUR EXTRA PARALLEL CONDITION HERE
= L 0.0
A L 0.0
L DB1.DBW 8
SP UpPulse
A L 0.0
A UpPulse
A SafetyInterlock
= RaiseCylinder
A L 0.0
L DB1.DBW10
SD CylindersUpTimer
A L 0.0
L DB1.DBW10
SD T24
You'll have to check through the code as I'm not the best at STL but hopefully you get the idea...
At the very least it will make the network more manageable.
The bld instructions are to enable logic to be converted to ladder.
L 0.0 is a local flag it automatically used as a temp mid coil, again you do not see this when it converts to ladder.
It may be easier to create your own temp flag and change the single ladder network to 4 ladder networks to display easier and to add your parallel branch.
Please accept my apologies Peter.
I edited the Backup Programme so I could do the Screen-shot and through rushing entered AN I 0.6 instead of ON I 0.6
it should look like this:
BLD 102
L DB1 DBW 8
SP UP PULSE T 5
A SAFETYLOCK I 0.6
ON SAFETYLOCK I 0.6
= RAISE CYLINDER Q 4.1
Sorry.
Simon, did you manage to make your First Screenshot in LAD if so what was the secret. That is exactly what I was trying to do at the outset of this Post.
1. Turn off symbol information etc.
2. Print screen
3. Paste into paint
4. cut out just the ladder to be displayed in the post
5. new paint file
6. paste cropped ladder image
7. SaveAs with jpg extension
