Point Level
You can configure whether each point should generate events using the Group
field for each point configuration. To disable event generation for a specific port,
set the value to 40000000.

Time Information
Each event may also carry the date and time information when it occurred. The
module 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 module may also be configured to not send any time information with each
event for certain data types. The following parameters may be used to control the
time information for each data type:
M_SP_NA Time Type : 2 #0=None, 1=CP24, 2=CP56 time
M_DP_NA Time Type : 2 #0=None, 1=CP24, 2=CP56 time
M_ST_NA Time Type : 2 #0=None, 1=CP24, 2=CP56 time
M_ME_NA Time Type : 2 #0=None, 1=CP24, 2=CP56 time
M_ME_NB Time Type : 2 #0=None, 1=CP24, 2=CP56 time
M_ME_NC Time Type : 1 #0=None, 1=CP24, 2=CP56 time
M_IT_NA Time Type : 2 #0=None, 1=CP24, 2=CP56 time
The master should periodically send a Time Synchronization command to the
module in order 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.
