Time Information
Each event may also send the date and time when it occurred. The PTQ-104S
module supports the CP56 time format (as defined in the protocol specification).
This format contains the millisecond, second, minute, hour, day, month and year
when the event occurred.
The PTQ-104S gateway may also be configured not to 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:
Note: The Client should send a Time Synchronization command to the module in order to
synchronize its date and time information, according to the protocol specifications. Depending on
certain parameters, as well as hardware limitations, the module may present some time delay over
time. The Client should periodically send time synchronization requests to the 104S module.
Invalid Bit Monitoring
This feature allows the application to set the invalid (IV) quality bit of the protocol
for all the monitored ASDU types supported. If the feature is enabled, the status
of the IV quality bit for each point configured by the user can be individually
monitored and controlled.
