Two Way Valve

Hello Expert

We have a 2-way valve with double acting actuator .

Valve has two feedback valve open and valve close

Valve has two Outputs Valve open and valve close.

I have gone through Vlv2Way but unable to apply for above situation as it has three outputs.

Can you please suggest which block from library should be used for above application.

Thanks

There is no standard block for this...

What you can do is the following:

1. Create a CFC chart where you put two VlvL blocks in it.

2. Go to the block folder of your project and go to FB1899, which is the VlvL block.

3. Copy all inputs, in/out and outputs and copy them in the Chart I/O, see next step

4. In CFC, select View->Chart I/O's and copy all the inputs, in/out and outputs.

5. Connect all inputs to the first VlvL block.

6. Create a copy of all inputs, in/out and outputs and rename those to for example: OpenAut_2.

7. Connect all modified parameters the second VlvL block.

8. You can now compile this CFC chart as block type. For this, go to CFC chart and select Chart->Compile->Chart as block type.

9. Fill in necessary data such as block number and create the block.

10. Now you can insert the new generated block in a new CFC chart, where you connect your input/output driver blocks and logic.

11. You can create a copy of a block icon of the type: VlvL and modify it, so you have 4 feedback signals, 2 outputs etc..

Hello Orcea

Thanks for reply .

But we have two feedbacks only as Valve Close and Valve open.

Again can we use P_open and P_Close outputs  and use RS flip flop to implement  above mentioned two way valve.

Thanking You
