Table 7.1 (continued) 46 Mode Description 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
