Streaming and Polling
The streaming and polling are used to monitor the signal flow of different parameters in a Signal Flow Designer.
Streaming can be beneficial when you need to constantly monitor a signal for a specific channel. If any changes are made to the signal flow design, the updated values will automatically be displayed through streaming. However, for non-streamable parameters, GTT will transmit a single command and receive the corresponding value from the device in response.
To access this feature, you will need a license for unlocking. Kindly contact the license administrator to obtain the necessary license.
The object tree displays filtered state variables that support streaming and polling.
Streaming state variables are highlighted in white, while polling state variables are highlighted in orange.
The default display of state variables in the object tree is set to show “after calculation” data for streaming out. However, if you want to display “before calculation” state variables, select the “Display IN Channels” option. The IN state variables indicated with a blue color and OUT state variables indicated with a red color, with keywords denoting their specified type.
