This is probably a module that uses CAN-bus as a bus interface. CAN-bus is used in automotive te reduce the number of wires in order to minimise cost. Other busses, used in industry are MODBUS, profibus, etc.
In a way you could see mySensors as a bus system as well as it is wireless Could be very beneficial for your challenge: each machine one or more sensor-node(s) - depends on the number of wires you'd like to monitor and the level of multiplexing you'd allow - and a gateway that is connected to a dedicated controller. This controller (I think not one of the controllers as used in the mySensors community) is used to translate the messages to instructions where to repair the yarns.
First thing to do for you is understand your real problem (yarns are breaking) and how you'd like to interact on this.
I think it's good to re-read the remarks @Bogus-Exception made! I strongly suggest you to read that again!
