11.3.The unit status and the LEDs
Function
TDM_CONTROL_STATUS_REPORT
Library TDM.LIB
Function symbol
Purpose
The function activates or deactivates the automatic status report
of the tdm R 360.
Parameter
Function inputs
Function outputs, none
Description
The status report provides the application software with all
relevant unit information:
•
currently displayed picture
•
currently displayed message
•
keyboard status (which key has been pressed or released)
•
LED is set or not set
•
unit status (e.g. preset value entry active)
TDM_CONTROL_STATUS_REPORT activates the automatic
status report. Each change of the above points is transferred to
the controller.
The current status can be evaluated with
TDM_REPORT_STATUS and TDM_REPORT_KEYDATA.
The function has to be called only once for switching on or
switching off. The execution of the function can then be blocked
via the input ENABLE. It is, however, useful to call the functions
in certain intervals (e.g. every 500 ms) when
TDM_CONTROL_STATUS_REPORT is active. That way it is
prevented that the monitoring of the unit status does not work
e.g. after a failure of the tdm power supply.
Name Data type Description
ENABLE BOOL TRUE: function is executed
FALSE: function is not executed
ON BOOL TRUE: automatic status report is
switched on
FALSE: automatic status report is
switched off
