Using the TEMS Info interface
The TEMS Info interface is available while the Traffic Controller is running. The TEMS Info
interface selects measured values, measurement results, and status messages at the
customer end from a permanent TCP/IP data stream.
The data to be transferred are freely definable. You can see which data protocol the
interface uses by referring to the source code (C#) for the
TEMS Info sample client
.
•
Further details on the message categories, types, and layout can be found in the
separate interface description for the TEMS Info interface
(8017178).
•
Please note: A maximum of 10 TEMS Info clients can be connected via the TEMS Info
interface. TEMS Manager does not count as a TEMS Info client.
Establishing a connection
The TCP/IP connection is established via the Info client. Several connections to the TEMS
Info server can be established, but each one has to be configured separately.
The connection is set up using the following sequence of messages:
TEMS Recorder
Direction
TEMS Info client
Establishing a socket connection
“Initialize” message
“Information” message
“Configuration” message
Tab. 19: TEMS Info interface (messages: establishing a connection)
If the server does not accept the client connection, the following messages are
exchanged:
TEMS Recorder
Direction
TEMS Info client
Establishing a socket connection
“Initialize” message
“Error” message
Tab. 20: TEMS Info interface (messages: connection not accepted)
Heartbeat
If “Heartbeat” messages are activated, they are sent regularly by the TEMS Recorder.
Based on the heartbeats received, the TEMS Info client can detect that the TEMS Info
server is ready for operation and can still complete its tasks.
