EtherCat Connection Status

I have a project working based on the LS example programs. Basically toggle bits to connect ethercat drives then servo on.

 

I would like to have the PLC perform this action on powerup, saving the operator the task of having to click buttons. I would like to look at a status bit that tells me if a particular ethercat axis is connected

    There is a global variable that can be used to tell the status of the link on the XBF-PN0xB modules. It is called _00x_LINKUP_INFO. It is true when a network cable is plugged in to the EtherCAT module and SubDevices are active on the network. Let me know if you are using the XMC instead. There is a similar variable for it.

      from my testing that bit is only detects the physical state of the network media,as I can issue a XPM_ECON and XPM_DCON without this bit changing state.

    You can try creating an initialization task. This task can call XPM_ECON to connect the EtherCAT network on CPU boot up. You will have to store the status just in case an error occurs and it needs to be done manually.

      Agreed, I will just make the connection in Init. And provide the operator a feedback status.
