12.3.6 Operation principle
Trip matrix logic (TMAGGIO) block is provided with 32 input signals and 3 output signals. The
function block incorporates internal logic OR gates in order to provide the necessary grouping of
connected input signals (for example, for tripping and alarming purposes) to the three output
signals from the function block.
Internal built-in OR logic is made in accordance with the following three rules:
1. when any one of first 16 inputs signals (INPUT1 to INPUT16) has logical value 1 (TRUE) the first
output signal (OUTPUT1) will get logical value 1 (TRUE).
2. when any one of second 16 inputs signals (INPUT17 to INPUT32) has logical value 1 (TRUE) the
second output signal (OUTPUT2) will get logical value 1 (TRUE).
3. when any one of all 32 input signals (INPUT1 to INPUT32) has logical value 1 (TRUE) the third
output signal (OUTPUT3) will get logical value 1 (TRUE).
By use of the settings
OffDelay the behavior of each output can be customized. The OnDelay is always active and will
delay the input to output transition by the set time. The
decides wether the output shall be steady with an drop-off delay as set by
give a pulse with duration set by
connected in an OR-function a new pulse will only be given on the output if all related inputs are
reset and then one is activated again. And for steady operation the of delay will start when all
related inputs have reset. Detailed logical diagram is shown in figure
