10Mbps transmission speed, the computer as the support of the flexible manufacturing system at the plant level, the requirements of more and more data flow,
High transmission speed can be guaranteed to increase the amount of transmitted data while maintaining the minimum time to transfer and receive data between programmable controllers AJ65DBTB1-32DT1 PDF.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on AJ65DBTB1-32DT1 PDF AJ65DBTB1-32DT1
This phenomenon is called the I/O delay time effect.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control AJ65DBTB1-32DT1 PDF.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three. DC input points: 8 points.

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 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 timmeliness is strong AJ65DBTB1-32DT1 datasheet.
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 AJ65DBTB1-32DT1 datasheet.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
