SEND_MSG function
Role
Implementation
Application example
This function is used to display a message with a dynamic variable (if necessary) on a CCX 17 console screen.
Implementation of the SEND_MSG function is developed in the Description of parameters (See Description of the parameters common to the different DOP
functions, p. 276) section.
The example given below makes use of the SEND_MSG function to display two status messages on the screen of a T CCX 1720 W console without an application.
This is connected to a TSX Premium via the AUX port (configured in UNI-TELWAY link, addresses 4 - 5).
Note: This same example, using a CCX 17 with application, is shown using the
DISPLAY_GRP function.
