A1SJ71AR21 | MITSUBISHI A1SJ71AR21 Melsecnet interface module

Brand: MITSUBISHI
Name: Melsecnet interface module
Model: A1SJ71AR21
PLC station distance: 500M.
Cable type: coaxial cable.
The function of the MELSECNET interface module is to connect the main CPU PLC to the MELSECNET data communication system.
As long as the switch on the component to set,
Can determine the CPU PLC is as the main station or in situ station.
There are two modules available for selection: one is the connection of the optical cable network and the network of the coaxial cable.
For a ANSCPU, up to only a piece of interface components can be inserted, A2ASCPU can be inserted 2.
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment.
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations.
In the case of the computer for the PLC handheld programmer compile user program.
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-to-one correspondence between the ladder diagram and the ladder diagram. Its characteristics are basically consistent with the ladder diagram language.

A1SS91 is used to insert a fixed control program in front of the user program to monitor the specific Y output.
Monitoring is carried out only when the CPU is in a state of running or stopping, and the monitoring failure is monitored in the suspended state.
When using this module, you can output from the I/O bus error contact or output from the running contact or the general contact output,
DC5V check can also be performed MITSUBISHI A1SJ71AR21 A1SJ71AR21

User program storage capacity: 8K step.
I/O points: 256 points.
Memory capacity: bytes 64K.
ANSCPU has been updated to ANSHCPU, and it has the following advantages.
16 bit dedicated microprocessor.
Large capacity batttery backup memory RAM MITSUBISHI A1SJ71AR21.
Extended I/O control capability.
Dedicated CC-Link instruction.
Capacity for extended comment storage.
Write speed processing.
