When X0 is turned on, Y0 bright lights;After 5s,Y0 lights off,Y1 bright lights;After 5s,Y1 lights off,Y2 bright lights,After another 5s,Y2 lights off,Y0 bright lights,Cycle through this sequence
There are three motors M1, M2, M3, press the start button to start M1, M2 starts after delay 5s, M3 starts after 16s.
The program uses a CPU Clock memory, Setting MB100 clock memory, the M100.0 change cycle is 0.1s. Enter the symbol address As I0.1, I0.1 positive edge down counter C0 to set the number, if I0.0 is 1, C0 minus 1 per 0.1s. Output symbol address Q0.0.
(1) control requirements. Freedom using a timer to set the clock pulse generator function (pulse duty factor 1: 1). (2) FC1 variable declaration table FC1 ladder program OB1 calls ladder program
00002,01600 fault information input, 00005 for the reset button, HR0000 is the state holding register 10000 for the fault display. When a fault 10,000 to ON10s.
When 00002 is turned on, TIM000 start timing, while 10000 is ON; after 0.8s TIM000 normally open contact closure, normally open contact disconnect, TIM001 start timing, while 10000 is OFF;After 0.6s, TIM001 the normally closed contacts open, TIM000 coil power, the normally closed contact closure, normally open contacts to open 10,000 and is ON; at … Continue reading PLC Flash power oscillation circuit Programming
TIM000 the timing process, the normally open contacts open, normally closed contact closure; regular time, the normally open contacts closed, the 10000 output is ON, after a scan cycle, TIM000 normally closed contacts disconnect, so that the coil power, normally open contact and open, so that 10000 is OFF.
Monostable circuit as an output circuit, when the input conditions are met, to produce a fixed-width output
When turned on simultaneously 00000,00001 10,000 output. When 00000,00001 not turned on, the output of 10001.When 00000 is turned on, not switched on 00001, 10002 output. When not connected to 00000, 00001 turned on 1003 output.
Loss of power-delay time relay, which when energized (timer input signal is ON), the timer output instantaneous action, normally open contact closure, normally closed contacts open; and when loss of power input (timer signal OFF), some time before the reset delay
