What is Motor Controller Data Link mean?

Bus monitoring is a term used in flight testing when capturing data from avionics buses and networks in data acquisition telemetry systems. Commonly monitored avionics buses include

ARINC Standard buses such as ARINC-429, ARINC 573, ARINC 717ARINC 629 also known as Multi-transmitter Data BusARINC 664 also known as Deterministic EthernetARINC 825 Controller Area Network (CAN)Common Airborne Instrumentation Systems (CAIS)Cross Channel Data Link (CCDL) / Motor Controller Data Link (MCDL)EthernetFibre ChannelFirewire, IEEE 1394IRIG-106 PCMMIL-STD-1553RS-232/RS-422/RS-485STANAG-3910Time-Triggered Protocol (TTP)

Typically a bus monitor must listen-only on the bus and intercept a copy of the messages on the bus. In general a bus monitor never transmits on the monitored bus. Once the bus monitor has intercepted a message, the message is made available to the rest of the data acquisition system for subsequent recording and/or analysis.

There are three classes of bus monitor:
