Data Listener Variables
Overview
The following variables can be used with the Data Listener and ODI Communication Sources.
Variable Name | Variable Syntax | Variable Type | Description |
---|---|---|---|
Data Listener Data | [Listener.data] | Source or Target | The current value of the data received by the data listener |
Data Listener Any Identifier | {identifier.any} | Source | Any Specific Identifier within the Status Type |
Data Listener Group Identifier | {identifier.group} | Source | Any Specific Identifier within the Status Group |
Data Listener Specific Identifier | {identifier.specific} | Target | The Specific Identifier received by the Data Listener |
TCP Data Time | [ListenerTCP.tcp_data_time] | Source or Target | Returns the amount of time in seconds since TCP Data was last received by the listener. |
The identifier.any
and identifier.group
variables can be used to ensure valid data is received as well as triggering events if a certain type of data is received.
For example, a status group of Quality could be created and then all quality related downtimes can be made a member of the Quality group. Now, if any downtime identifier within the quality groups is received by the data listener then an action can take place such as turning on a pole light using the SRC.
Examples of using the data listener variables in expressions are shown on the Unsolicited Data Collection page.
