(inP = 1)

Input functions: Input 1 – count, Input 2 – start/stop, Input 3 – reset, Input 4 – block

Operating principle: Pulse count from zero upwards. When the setpoint is reached, the corresponding output is switched and the counter is reset

{t₁–t₂} – blocking signal the counting inputs;

t₃ – switching of output 2 in case of coincidence of values of the counting register and setpoint 2;

{t₄–t₅} – stop-start signal;

t₆ – switching of output 1 in case of coincidence of values of the counting register and setpoint 1

(inP = 2)

Input functions: Input 1 – count, Input 2 – start/stop, Input 3 – reset, Input 4 – block

Operating principle: Counting pulseopw6z7ds from the highest by the module setpoint to zero (decreasing). When the zero is reached, corresponding output is switched and the setpoint register is written to the count register

{t₁–t₂} – blocking signal on the counting inputs;

t₃ – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2;

{t₄–t₅} – stop-start signal;

t₆ – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1

(inP = 3)

Input functions: Input 1 – count, Input 2 - direction of count, Input 3 – reset, Input 4 – block

Operating principle:

Two inputs are used: counting pulses are applied to the first, the status of the second determines the direction of the count. If there is a "logical 0" at the second output, the counter increases its value, if there is a "logical 1" it decreases. In this type two setpoints can be set, meanwhile:

• if the setpoints have the same sign, counter resets after reaching the setpoint, that is larger by module.

{t₁–t₂} – the decrease in the value of the counting register (impulse appears at the counting input 2);

t₃ – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2;

t₄ – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1

• if the setpoints have different signs, the counter is reset after reaching each value

{t₁–t₃} – the decrease in the value of the counting register (impulse appears at the counting input 2);

t₂ – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2;

t₄ – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1

Notice

If the setpoint is set as zero, it is considered to be disabled, and the counter does not use it.

(inP = 4)

Input functions: Input 1 – count 1, Input 2 – count 2, Input 3 – reset, Input 4 – block

Two counting inputs are used: pulses on Input 1 increase the value of the counting register, and the pulses on Input 2 decrease it. In this case, two setpoints are used (after reaching each of them, the corresponding output switches):

Operating principle:

• if both setpoints have the same sign, counter does not reset after reaching lesser (by module) value. Otherwise, corresponding output is switched each time counter reaches this setpoint, regardless of the direction of the count

t₁, t₃, t₅ – moments of the decrease in the value of the counting register (impulse appears at the counting input 2);

t.₂ – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2;

t₄ – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1

• if the setpoints have different signs (the first is greater than zero, and the second is smaller), then counter resets after reaching each setpoints

t₁, t₃ – moments of the decrease in the value of the counting register (the appearance of the pulse at the counting input 2);

t₂ – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2;

t₄ – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1

(inP = 5)

Input functions: Input 1 – count 1, Input 2 – change counting direction (reverse), Input 3 – reset, Input 4 – block

Operating principle:

After the power is on, the device is in the "count-up" mode by default. For reversing count it is necessary to apply signal to input 2.

Thus there are two counting inputs: pulses on Input 1, lead to an increase in the value of the counter, the counting direction is changed cyclically with each incoming pulse on Input 2. In this case, two setpoints are used (after reaching each of them, the corresponding output switches):

• if both the setpoints have the same sign

t₁, t₂ – moments of change of the counting direction (the appearance of the pulse at the counting input 2);

t₃ – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2;

t₄ – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1

• if the setpoints have different signs

t₁, t₃ – moments of change of the counting direction (the appearance of the pulse at the counting input 2);

t₂ – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2;

t₄ – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1

(inP = 6)

Input functions: Input 1 – count 1, Input 2 – count 2, Input 3 – reset, Input 4 – block

Operating principle:

The counting direction is determined by the meanders that come on two inputs. If the first meander is ahead of the second one, the counter counts the pulses at the first input in the increase mode, and if it lags – in the decrease mode. In this case, two setpoints are used (after reaching each of them, the corresponding output switches):

• if both the setpoints have the same sign

t₁, t₂, t₅, t₆ – meander at input 1 is ahead of the meander at the input 2,

the counter counts in the mode of increasing the value of the count register;

t₃, t₄ – the meander at input 1 lags behind the meander at input 2,

the counter counts in the mode of decreasing the value of the counting register;

t₇ – moment of switching of output 2 for the time of exceeding the value of setpoint 2 by the counting register;

t₈ – moment of switching of output 1 for the time of exceeding the value of setpoint 1 by the counting register

• if setpoints have different signs

t₁, t₂ – the meander at input 1 lags behind the meander at input 2,

the counter counts in the mode of increasing the value of the count register;

t₃ – moment of switching of output 2 in case of coincidence of values of the counting register and the setpoint 2;

t₄, t₅ – the meander at input 1 is ahead of the meander at input 2,

the counter counts in the mode of increasing the value of the count register;

t₆ – moment of switching of output 1 in case of coincidence of values of the counting register and the setpoint 1

Note

After reaching the physical limit of the count (if the counter does not reset after reaching the setpoint), the device transfers the overflow result and continues the count.
