    Latch Relay and Unlatch Relay, Should be a single component.

    I wanted to use a latching relay so I inserted the symbol for a latching relay from the Component Menu on a rung, but when i go to insert the unlatch input or coil for that same latching relay it assigns a new coil without asking me for the parent latching relay. the item that I am trying to model is an 8501KL12V20 Latching Relay from Square D where you have a common connection for two inputs. One input latches the relay and the other input unlatches the relay. How do I make this happen? I need it to be a single component.

    G'day MCI

     

    My solution was to draw a three wire coil using the standard relay coil.

     

    The unlatch wire was connected to the bottom of the coil.

     

    I then made a special block.

    I created a special block that has both the latch and unlatch coils in it.

     

    There is also the ability to tie two parent blocks together within ACADE using the WD_ALTTAG attribute (I think that's it).
