Time Information
Each event may also carry the date and time information when it occurred. The
gateway supports the CP56 and CP24 time formats (as defined in the protocol
specification).
The CP56 time format contains the milliseconds, seconds, minute, hour, day,
month and year when the event has occurred.
The CP24 time format contains the milliseconds and minutes when the event has
occurred.
The gateway may also be configured to not send any time information with each
event for certain data types. The following Time Type parameters may be used to
control the time information for each data type:
The Master should periodically send a Time Synchronization command to the
gateway driver to synchronize its date and time information. This is a very
important step in order to make sure that the Master and the slave are both using
the same time information.
