pneumatic cylinder

[reteP]

Hi Lava's,

 

I have an application with pneumatic cylinders. I want used LVOOP, because in the future it will better for reuse code.

 

Each cylinder has 2 sensor and 1 pneumatic valve. Sometimes has 1 or 2< sensors but now i need solve standard construction.

Class cylinder has attributes:

- origin enum(byDef, bySen) specifies how to init (by default or by sensors)

- default (bool)                      default position cylinder 

- direction (bool)                   direction of movement

- actual (bool)                       actual position of cylinder

- timelimit (num I32)              time to carry out

- timeout (bool)                     time has elapsed

- retry (bool)                         allow retry if was timeout

 

and methods:

Create()

Destroy()

Init()

CheckPosition()

Move()

Retry()

 

I need help with implementation state machine in to class.

No body help me ????

It is a little unclear what you need. The state diagram you attached appears to just correspond to the different methods in the class. What exactly are you struggling with?

Hi James,

 

I want create universal class for control pneumatic cylinder. My app has 5 cylinder they are work in seqvence. For exaple: i tell in my app "closs gate" and i must chcek position, if is good - move the cylinder, if is not good then chceck time if is timeout and allow retry - execute RETRY and then chceck position. Position corect - move a cylinder to desired position.

 

Seqvence cylinder: Check position -> Move -> Check position then cylinder report task done and app go to the next STATE in state machine.

 

I have methods for this steps and i dont know how to implement in my app. My app has 2 controlls section ( pneumatic & hydraulic ) pneumatic cylinder manipul with part in machine and hydraulic testing this part. 

 

PS: so sorry for my english (:
