How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points A7BDE-J71LP21 Manual A7BDE-J71LP21
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book A7BDE-J71LP21 Manual. DC input points: 32 points.
Input voltage and current: 3/7mA, DC12/24V.
Response time: 10ms.
Positive pole sharing.
Output points: 16 points.
Output voltage and current: 100mA/1, DC12/24V point.
Response time: 2ms.
48 point /1 public side (input and output sharing).
Output form: transistor output, leakage type.
40 pin connector.
Number of stations: 1 stops A7BDE-J71LP21 Manual.
Type remote I/O unit (twisted pair data connection).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system MITSUBISHI MELSECNET/10 INTERFACE BOARD Manual.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures MITSUBISHI MELSECNET/10 INTERFACE BOARD Manual.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong MITSUBISHI MELSECNET/10 IINTERFACE BOARD Manual A7BDE-J71LP21 User's Manual.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy too guarantee the timeliness A7BDE-J71LP21 Manual.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
