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
00002 is the timer input,10000 is the timer output coil.00002 closed, TIM000 timing ，Arrived at the designated time, 10000 is ON;00002 off, TIM001 timing， Arrived at the designated time, so that 10000 is OFF.
In the elevator shaft on each floor is equipped with a magnetic sensors, respectively 1YG, 2YG, 3YG, 4YG, 5YG, while the car is equipped with a side length of the magnet separator plate, if the elevator up from the first floor, then magnet separator plate and then click insert sensor. When the magnet separator plate … Continue reading PLC floor control loop
SET: set command, keeping the action ON the directive.RST: reset instructions, keeps the action OFF directive.SET command can be used to Y,M,S,T,C Y,M and S,RST directives can be used to reset or D,V and z-zero Word elements.If X0 figure 1 normally open contact connected, Y0 to ON and keep the State, even if the X0 … Continue reading Mitsubishi PLC SET, RST instruction
PLS (Pulse): rising differential output directive.PLF: falling edge of differential output directive.PLS and PLF command can only be used for the output relays and auxiliary relays (does not include special auxiliary relays). M0 in the figure only in the X0 normally open from open to close (X0 rising edge) when a scan cycle for ON,M1 … Continue reading Mitsubishi PLC PLS, PLF instruction
