Table 7.1 (continued) 43 Mode Description Count- down (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
