Input and output points: 480 points.
Input / output data points: 480 points.
Program capacity: 8k.
Basic command processing speed (LD command) s:1.25.
RAM memory capacity: 32K, power supply (DC24V).
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance A1NCPUP21 Hardware Manual A1NCPUP21 User's Manual.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage A1NCPUP21
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load A1NCPUP21 Hardware Manual A1NCPUP21 User's Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
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 A1NCPUP21 Hardware Manual A1NCPUP21 User's Manual. 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. 32: terminal line adapter 0.75mm2 (AGW18).Input type: DC input, positive common end.
Input points: 16 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/4mA.
By embedding the product into the customer base, the remote I/O station can be simply developed.
Mitsubishi Co PLC network inherited the traditional use of the MELSEC network,
And make it better in terms of performance, function, easy to use etc..
Provides a layer of three layers of clear network, to provide the most suitable network products for a variety of uses.
The information layer /Ethernet (Ethernet) information layer is the highest level of the network system,
Mainly in the PLC, the device controller and production management with PC transmission between production management information, quality management information and the operation of equipment, etc.,
Information layer using the most common Ethernet.
It is not only able to connect the PC system UNIX, windows system, etc.,
And can connect a variety of FA devices.
The Ethernet module has the function of Intternet e-mail receiving and sending,
The user can send and receive the production information conveniently in any place of the world,
Build a remote monitoring management system A1NCPUP21 Hardware Manual A1NCPUP21 User's Manual.
At the same time, tthe use of the Internet FTP server functions and MELSEC protocol can be very easy to achieve the program upload / download and transfer of information A1NCPUP21 Hardware Manual A1NCPUP21 User's Manual.
