I have an integration challenge where a [black box] control system is controlling, among other things, a Yaskawa Sigma 7 servo controller on EtherCAT.
My goal is to read the absolute position of the Yaskawa servo's absolute encoder. I know that's part of the EtherCAT data being exchanged between the two, and that the Sigma 7 uses the CiA402 Drive Profile, so parsing the data should be do-able.
My reading of the data doesn't need to be fast; it's literally going on an HMI screen. A quarter second would be plenty.
I know I could try a Hilscher NetTAP NT151-RE-RE and ask them to write the encoder position to it as an EtherCAT slave, then I can read it as an EtherNet/IP slave (I'm running a CompactLogix).
But does anyone know of an EtherCAT device that can "listen" to things like the CiA402 profile connection passively, once it's identified between two devices ?
