Logic and latches
Function blocks in the group “Logic and latches”. Each link opens the block page; sorted by library and name.
| Block | Page title | Library | What it is for |
|---|---|---|---|
| AND | AND | Basic Digital Boxes | Logical “AND” of two or more inputs. |
| bd49_singlealarmmemory | Single alarm memory | Basic Digital Boxes | This block is dedicated to deal with alarm states. |
| bd50_alarm_memory | Alarm memory | Basic Digital Boxes | The block is an alarm memory, with up to 16 alarms. |
| bd51_boolean_memory | Boolean memory | Basic Digital Boxes | The block is a single-cycle signal delay block, or a boolean signal memory cell. |
| bd52_flipflop | Flip-flop | Basic Digital Boxes | The block controls its output value based on inputs, which read rising or falling edge, and thus set or reset the output. |
| bd53_latchflipflopnode | Latch flip-flop | Basic Digital Boxes | The block is a gate for logical signals. |
| bd56_singlealarmmemorydelay | Single alarm memory with delay (v1.1) | Basic Digital Boxes | The block is an alarm memory which responds after a time delay only. |
| bd57_alarmmemoryext | Extended alarm memory | Basic Digital Boxes | The block is an alarm memory with up to 16 alarm inputs. |
| F_TRIG | F_TRIG | Basic Digital Boxes | The block detects a falling edge and generates a pulse on the output with duration of one cycle. |
| NEG | NEG | Basic Digital Boxes | The function negates the input. |
| NOT | NOT | Basic Digital Boxes | The function negates the input. |
| OR | OR | Basic Digital Boxes | The function performs a logical OR of two or more inputs. |
| R_TRIG | R_TRIG | Basic Digital Boxes | The block sends a pulse with duration of one cycle on the input signal's rising edge. |
| ROL | ROL | Basic Digital Boxes | The function rotates the input vector to the left. |
| ROR | ROR | Basic Digital Boxes | The function rotates the input vector to the right. |
| RS | RS | Basic Digital Boxes | Classical RS Flip-Flop circuit. |
| SHL | SHL | Basic Digital Boxes | The function moves the bit pattern from right to left. |
| SHR | SHR | Basic Digital Boxes | The function moves the bit pattern from left to right. |
| SR | SR | Basic Digital Boxes | The circuit acts as a classical RS flip-flop circuit. |
| Toggle | Toggle | Basic Digital Boxes | Block works as a toggle switch, Input In reacts on raising edge, The first raising edge switches the output to TURE. |
| XOR | XOR | Basic Digital Boxes | Function calculates the exclusive disjunction of two or more inputs. |
