RollingTimestamp
Data Type Definition
REAL Channel data in scaled Engineering Units.
DINT[2] 64-bit timestamp indicating when all 8 channels were
last sampled in terms of CIPSync time.
DINT 16-bit timestamp that 'rolls' from 0...32,767 ms.
Compatible with existing PID/PIDE instructions to
automatically calculate sample deltas. With this module,
this PID/PIDE instruction uses the RPI because there is no
RTS available.
For more information on the Rolling Timestamp, see
page 23.
