Built-in DOP functions
DISPLAY_GRP function
Role This function is used to simultaneously display a group of messages contained in the CCX17 operator dialog console memory.
Implementation
Specific parameter:
Message group number
Implementation of the DISPLAY_MSG function is developed in the Description of parameters (See Description of the parameters common to the different DOP
functions, p. 276) section.
The Message group number parameter defines the group message identifier contained in the CCX 17 memory.
Its value is between 1 and 100.
Example of application
The example given below makes use of the DISPLAY_GRP function to display a group of two status messages on the screen of a T CCX 1720 W console containing 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 without application, is shown using the
SEND_MSG function.
