Python连接FactoryIO仿真控制练习（二）

1、PythonFactoryIO仿真控制练习（）连接仿真控制练习（）我想了下在PLC中通过SCL进定时器、计数器、脉冲检测等功能块的实现逻辑，重新进了功能实现。传送带控制加了延时停机定时器，当超出时间未检测到离开传送带末端传感器信号时，传送带停运。、定时器：参考在PLC中使SCL实现定义定时器的般逻辑，实现如下：self.et =0-self.cycle_time =self.end_time - self.start_timeif enable:if self.et 0 else 0self.timer_1.timing(self.counter_on_conveyor and not exi

2、t_signal, 30000)if self.timer_1.timer_on:return self.run_control五、主循环传送带超时时间设置为30s，当传送带末端传感器接通时，会复位定时器：当定时器到达定时时间，将强制停传送带运，并复位定时器，并等待下次的触发信号：if _name_ =_main_:master =mt.TcpMaster(host192.168.29.50) # host=192.168.29.50, port=502, timeout_in_sec=5.0master.set_timeout(5.0)InputBool =list(master.execu

3、te(255, md., 0, 4)output_coils_bool =master.execute(255, md.WRITE_MULTIPLE_COILS, 0, output_valueOutputBool)time.sleep(0.5)完整代码如下，使例程为FromAToB：import modbus_tk.modbus_tcp as mtimport modbus_tk.defines as mdimport tkinter as tkdef control(self, enter_signal, exit_signal):-self.counter_enter_value =se

4、lf.enter_counter.countering(enter_signal)self.counter_exit_value =self.exit_counter.countering(exit_signal)self.counter_on_conveyor =self.counter_enter_value - self.counter_exit_valueself.run_control =1 if self.counter_on_conveyor 0 else 0self.timer_1.timing(self.counter_on_conveyor and not exit_sig

5、nal, 30000)if self.timer_1.timer_on:class MyTimer:定时器def _init_(self, cycle, my_time): 以循环周期为时基self.et =0def timing(self, enable, pt):-self.end_time =int(time.perf_counter() *1000)self.cycle_time =self.end_time - self.start_timeif enable:if self.et pt:self.et +=self.cycle_timeself.timer_on =0else:se

6、lf.timer_on =1else:self.et =0self.timer_on =0self.start_time =int(time.perf_counter() *1000)self.clk =0-return str(self.counter_current_value)-if self.reset_counter_signal:self.counter_current_value =0self.reset_counter_signal =0return 0self.clk =clkelse:self.out =0if _name_ =_main_:master =mt.TcpMaster(host192.168.29.50) # host=192.168.29.50, port=502, timeout_in_sec=5.0master.set_timeout(5.0)InputBool =list(master.execute(255, md., 0, 4)conveyor_1_enter_signal =InputBool
