The data stored in the operating data memory, the monitoring signal memory and the event memories are date- and time-tagged. For correct tagging, the date and time need to be set in the P632.

The time of different devices may be synchronized by a pulse given to an appropriately configured binary signal input. The P632 evaluates the rising edge. This will set the clock to the nearest full minute, rounding either up or down. If several start/end signals occur (bouncing of a relay contact), only the last edge is evaluated.
