This package provides blocks with Boolean input and output signals to describe logical networks. A typical example for a logical network built with package Logical is shown in the next figure:
The actual value of Boolean input and/or output signals is displayed in the respective block icon as "circle", where "white" color means value false and "green" color means value true. These values are visualized in a diagram animation.
Name | Description |
---|---|
And | Logical 'and': y = u1 and u2 |
Or | Logical 'or': y = u1 or u2 |
Xor | Logical 'xor': y = u1 xor u2 |
Nor | Logical 'nor': y = not (u1 or u2) |
Nand | Logical 'nand': y = not (u1 and u2) |
Not | Logical 'not': y = not u |
Pre | Breaks algebraic loops by an infinitesimal small time delay (y = pre(u): event iteration continues until u = pre(u)) |
Edge | Output y is true, if the input u has a rising edge (y = edge(u)) |
FallingEdge | Output y is true, if the input u has a falling edge (y = edge(not u)) |
Change | Output y is true, if the input u has a rising or falling edge (y = change(u)) |
GreaterThreshold | Output y is true, if input u is greater than threshold |
GreaterEqualThreshold | Output y is true, if input u is greater or equal than threshold |
LessThreshold | Output y is true, if input u is less than threshold |
LessEqualThreshold | Output y is true, if input u is less or equal than threshold |
Greater | Output y is true, if input u1 is greater than input u2 |
GreaterEqual | Output y is true, if input u1 is greater or equal than input u2 |
Less | Output y is true, if input u1 is less than input u2 |
LessEqual | Output y is true, if input u1 is less or equal than input u2 |
ZeroCrossing | Trigger zero crossing of input u |
LogicalSwitch | Logical Switch |
Switch | Switch between two Real signals |
Hysteresis | Transform Real to Boolean signal with Hysteresis |
OnOffController | On-off controller |
TriggeredTrapezoid | Triggered trapezoid generator |
Timer | Timer measuring the time from the time instant where the Boolean input became true |
LogicalDelay | Delay boolean signal |
RSFlipFlop | A basic RS Flip Flop |
TerminateSimulation | Terminate simulation if condition is fulfilled |
