In this specific embodiment, the PLC controller has been selected Siemens S7-200 series CPU224PLC for use, and the PLC controller has following advantage:
1, real-time
L is controlled to be prerequisite because controller product design and exploitation are based on, and signal processing time is short, and speed is fast.
L is based on the speed of signal processing and program running, and PLC is through being usually used in handling the security interlocking protection of industrial control device.
L more can satisfy each big field large, medium and small type Industry Control project.
2, high reliability
The all I/O input/output signals of l all adopt photoelectricity to isolate, and electricly between the external circuit that makes industry spot and the controller internal circuit go up isolation.
Each input of l all adopts shielding measure, to prevent noise.
L adopts the Switching Power Supply of function admirable.
The components and parts that l just adopts carry out strict screening.
The autodiagnosis function that l is good, in case power supply or other soft, hardware generation abnormal conditions, CPU adopts an effective measure immediately, enlarges to prevent fault.
The big type controller of l can also adopt by two CPU and constitute redundant system or have three CPU to constitute voting system, and realizes that power module is redundant, the IO module redundancy, and reliability is further improved.
3, system configuration simple and flexible
L controller product category is various, and it is large, medium and small etc. that scale can be divided.
L I/O fastener kind is abundant, can be different according to the functional requirement of automatic control Project Realization, and carry out the difference configuration.
L satisfies under the Control Engineering needs prerequisite, but I/O fastener flexible combination.
4, the I/O fastener that enriches
The l controller is directed against the on-site signal of different industrial automatic control engineerings, as: exchange or direct current; Switching value or analog quantity; Voltage or electric current; Pulse or current potential; Forceful electric power or light current etc. have the device or the equipment of corresponding I/O module and industry spot, as: button, travel switch, directly connect near switch, sensor and transmitter, solenoid, control valve etc.
