Detailed Description

A device's distributed-clock configuration (ENI Slave/DC).

Present only for a device the master synchronises. Motion Master runs the bus in free-run and writes no DC element, so today this is what a reader finds in somebody else's document.

cycleTime1Ns is not the SYNC1 cycle time. ETG.2100 Table 32 defines it as SYNC1 cycle − SYNC0 cycle + SYNC0 shift, a derived value, so it can be neither read nor written as if it were the raw register figure.
