I'm unable to activate the PAL-EIP valves with the BRX PLC.

I'm having an issue with the PAL-EIP, which has four PAL-V2-32C valves. When I try to activate and deactivate the valves, I also have a PAL-EAD connected with another four PAL-V2-32C valves. I've configured everything and am sending messages via EtherNet/IP with the BRX PLC, but the valves aren't activating. Could you help me understand the correct way to send the messages? Additionally, could the NS error message 'Scanner is not connected to the module' be causing the communication issue? If so, how can I resolve it?"

    There is an example project available for the PAL device on the product page. You should reference that if using Explicit messaging.

    https://www.automationdirect.com/adc/shopping/catalog/valves/directional_control_solenoid_valves/control_interfaces/pal-eip

     

    Having said that, with v2.10, Domore has added Implicit scanner functionality and I recommend using that instead.

     

    To set it up, with your project open, first click on the Configure icon or go to PLC> System Configuration...

     

    Select EtherNet/IP Scanner from the Configuration list

    PAL_EIP2 

    Enable E/IP scanner service and click on Find Adapters

    PAL_EIP3 

    If your PAL device is on the network, it should appear in the list, along with it's associated EDS file. Double click on the EDS file name.

    PAL_EIP4 

    In the window that opens, Click the "Add" button, select "Exclusive Owner" and click OK.

    PAL_EIP5 

    In the adapter setting window, click the + button for the Local Addr field. Do this for T>O and O>T data

    PAL_EIP6 

    I have created a single data block (unsigned byte) of the input data naming it PalInputData

    PAL_EIP7Same thing for Output data. Click the + button for Local Addr and create a single data block. This was named PalOutputData

     

    The new T>O and O>T date blocks should now be displayed. I also renamed the device to @PAL_EIP

    PAL_EIP9Click OK and your device should now be displayed in the scanner config window.

    PAL_EIP10To control the (16) valves, i want to use C-bits. I used a COPY instruction to write C0-C15 to the first 2 bytes of the PalOutputData block.

     

    PAL_EIP11I Nicknamed C0-C15 to PAL_Valve (1-16) using documentation editor.

    After sending the project to the PLC, I added my scanner device to DataView along with C0-C15 to test communication and valve control.
