Linking Solenoid Output to Double Solenoid Valves

[Anonymous]

On my pneumatic layout I have multiple 3- Position Double Solenoid Closed Center valves. I am trying to link the valves with the PLC outputs, but am encountering a few issues:

1. The A and B solenoids of the valve are linked to seperate outputs on the PLC. Thus, I have two solenoid coils per valve. When I enter the Catalog Data for the electrical solenoid, the BOM report lists twice the number of valves. What should I do in the Catalog Data field to state that two solenoids belong to a certain valve. I think that this would require some type of parent-child relationship, but am not very familiar with this concept.

2. How can I link the name of the each output (SOL 438/439) to the correct side of the valve? Also, how can I create a link between the object in the pneumatic drawing and the electrical drawing (they are both in the same project)?

Thanks for any advice, and please refer to the attached pictures.

Hi,

Look under AutoCAD Electrical Help -> Advanced Productivity -> Set up peer
to peer Component relationships. This should help you in creating a link
between your pneumatic and schematic diagrams.

Regarding the Catalog data for BOM report you can have the catalog
information in any one coil and leave the other coil blank. Alternatively,
as the pneumatic solenoid is in the same project you can consider having the
catalog information on the valve this will show up in your BOM.

Hope this works for you.

Well,

Copy tag works great for 1/2 coils on the valve.

WDTAGALT works great for referencing the valve as a peer of BOTH solenoid coils.

But how do I link to coils to a single valve with the following rules:

1. SOL%S%N must be from the coils line number reference. ex. 406 for sheet 4 line 6.

2. It would be ideal to setup a child/parent type relationship, but I need to maintain the tag names on the children.

3. I want to place the SOL tag somewhere in the valve acad "block" as in the drawing above.

Please help! Any tips? TIA

It sounds to me like you have two solenoids within one valve. One way to document this by inserting a solenoid symbol off of each PLC output and let each have a unique tag. But only enter BOM data in one and only link one to the pneumatic drawing via the WDTAGALT attribute.

Another option is to indeed create a second SOL schematic symbol named, HSV2 and change the TAG1 attribute name to TAG2. Just copy the HSV1 and rename it to HSV2 and change the TAG1 to TAG2. Insert the HSV1 first. Then insert HSV2 and pick HSV1 when prompted for parent/sibling. From the edit screen of the parent, HSV1, click Show/Edit Misc. and enter the valve TAG from the pneumatic drawing into WDTAGALT. Go to the pneumatic drawing and edit the valve and enter the schematic TAG of the HSV1 as the WDTAGALT attribute value. I just tested it and it works. I will attach an HSV2 I created in my JIC125 library folder. If your solenoids are vertical, you may need to create a VSV2.
