Table 7.1 (continued) 51 Name of the mode Input functions Principle of operation Illustration • 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
