MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc A3ACPUR21 Manual. . DC input points: 8 points.
Input voltage and current: 7mA, DC24V.
Response time: 10ms.
8 point /1 a public side.
Positive / negative sharing.
Output points: 8 points.
Output voltage and current: DC24V, 0.3A/1 point, 2.4A/1 common end.
Response time: 2ms.
8 point /1 a public side A3ACPUR21 Manual.
Output form: transistor output, leakage type.
34 point terminal station.

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 Programmable Logic Controller Manual MITSUBISHI Programmable Logic Controller Manual.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
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 Programmablle Logic Controller Manual A3ACPUR21 Programming 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 A3ACPUR21 Manual.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
