Rolling Timestamp of Data

For the analog output modules, the rolling timestamp value is updated only when new values are applied to the Digital to Analog Converter (DAC). The echoed data is updated at the same time.

The rolling timestamp is a continuously running 15-bit rolling timestamp that counts in milliseconds from 0…32,767 ms. The rolling timestamp value is reported in the I.Chxx.RollingTimestamp tag for the analog I/O modules.
