Slide 53:

What Are You Trying to Do as ELMS?

ELMS NTCIP 1213 User Needs in Detail The user needs are organized as follows:

 

Slide 54:

What Are You Trying to Do as ELMS?

ELMS NTCIP 1213 Operational User Needs Provide Live Data (mandatory)

2.5.1.1 Provide Live Data

One operational environment allows the management system to monitor and control the device by issuing requests (e.g., requests to access information, alter information, or control the device). In this environment, the device responds to requests from the management station immediately (e.g., through the provision of live data, success/failure notice of information alteration, or success/failure of the command).

 

Slide 55:

What Are You Trying to Do as ELMS?

ELMS NTCIP 1213 Operational User Needs

Provide Off-Line Logged Data

2.5.1.2 Provide Off-Line Log Data

Some operational environments do not have always-on connections (e.g., dial-up links). In such environments, a transportation system operator may wish to define conditions under which data are placed into a log, which can then be uploaded at a later time. For example, the operator may wish to manage the ELMS device so that it autonomously maintains a log of whenever a specific luminaire is tufli ed on or off.
