Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units A1SD71-S2 User's Manual. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words A1SD71-S2
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure A1SD71-S2 User's Manual.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. MELSECNET/MINI (-S3) data link system, A2C system transfer converter.
Plastic fiber cable -SI optical fiber cable.
MITSUBISHI PLC protection and chain procedures A1SD71-S2 User's Manual.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations.
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..
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation. RS-422 1 channel, RS-422/485 1 channel.
Transfer speed: 0.3-19.2kbps.
Equipment layer / field bus CC-Link device layer is the PLC and other control devices and sensors and drive devices connected to the field network,
Network for the lowest layer of the whole network system.
Using CC-Link field bus connection, the number of wiring is greatly reduced,
Improve the maintainability of the system.
And, not just the amount of data ON/OFF and other switches,
Can also be connected to the ID system, bar code reader, invverter, man-machine interface and other intelligent devices,
From the completion of a variety of data communication, the management of the terminal production information can be realized,
On the centralized management of the state oof the machine movement,
Make maintenance work efficiency also greatly improved A1SD71-S2 Manual A1SD71-S2 Manual.
Q series PLC in the use of CC-Link function better,
And easier to use.
