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 MITSUBISHI A0J2E-E28AS A0J2E-E28AS
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 A0J2E-E28AS.
Q series PLC in the use of CC-Link function better,
And easier to use. CPU:A3UCPU PLC is the same.
PLC program capacity: 30K step.
I/O points: 2084 points.
Processing speed (sequential order): 0.15 s/ step.
Control axis: up to 32.
Servo program capacity: 14K step.
Servo amplifier: SSCNET connected external servo amplifier MITSUBISHI A0J2E-E28AS.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive A0J2E-E28AS MITSUBISHI.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference A0J2E-E28AS MITSUBISHI. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC. NSD servo system.
A73CPU (P21/R21) -S3 dedicated.
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 A0J2E-E28AS MITSUBISHI.
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.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A0J2E-E28AS.
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% MITSUBISHI A0J2E-E28AS.
The following describes the centralized control system I/O points of the estimate.
