3C-2V/5C-2V coaxial cable.
Double loop.
Remote I/O network (remote control station).
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps AJ71QC24.
Design PLC peripheral hardware circuit AJ71QC24.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram AJ71QC24.
So far the system''s hardware electrical circuit has been determined.
RS-232 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 MITSUBISHI AJ71QC24.
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, inverter, 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 of the machine movement,
Make maintenance work efficiency also greatly improved MITSUBISHI AJ71QC24 MITSUBISHI AJ71QC24.
Q series PLC in the use of CC-Link function better,
And easier to use. Input and output points: 256 points.
Input / output data points: 256 points.
Program capacity: 6k.
Basic command processing speed (LD command) s:1.0.
Internal storage RAM memory capacity: 16k.
Optical data communication line function with power supply.
Input / output data control mode conversion.
It is possible to enter the control of the output data as the following 3.
(1) input: direct mode, output: direct mode.
(2) input: I/O impression update mode, output: direct mode.
(3) input: I/O impression update mode, output: I/O impression update mode.
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. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
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 iinstalled in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure AJ71QC24.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
