13.2.6 Operation principle
The 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 grouping of connected input signals 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 the first output signal (OUTPUT1) will get logical value 1.
2. when any one of second 16 inputs signals (INPUT17 to INPUT32) has logical
value 1 the second output signal (OUTPUT2) will get logical value 1.
3. when any one of all 32 input signals (INPUT1 to INPUT32) has logical value 1
the third output signal (OUTPUT3) will get logical value 1.
By use of the settings ModeOutput1, ModeOutput2, ModeOutput3, PulseTime,
OnDelay and 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
ModeOutput for respective output decides whether the output shall be steady with an
drop-off delay as set by OffDelay or if it shall give a pulse with duration set by
PulseTime. Note that for pulsed operation and that the inputs are 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. For steady operation the OffDelay will start when all
related inputs have reset. Detailed logical diagram is shown in figure
