Table 7.1 (continued) 48 Mode Description 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
