Optional features of memory card (A/FX compatible).
4MB extended memory.
Applicable models: A985 (-V) /975/970/A960GOT (-B) /A956WGOT. Analog channel: 4 channels A2ASCPU-S30 PDF.
Input / output (resolution): 0 ~ 4000.
Conversion speed: 100ms/4 channel.
Analog module installation.
Power supply: AC170V ~ 264V.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program A2ASCPU-S30
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system A2ASCPU-S30 PDF.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong A2ASCPU-S30 PDF.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy to guarantee the timeliness MITSUBISHI Programming Manual .
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer A2ASCPU-S30 Manual. Input and output points: 480 points.
Input / output data points: 480 points.
Program capacity: 8k.
Basic command processing speed (LD command) s:1 MITSUBISHI Programming Manual . 25.
RAM memory capacity: 32K, power supply.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
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 MITSUBISHI Programming Manual .
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.
User program storage capacity: it is a meaasure of how much the user application can store the number of indicators A2ASCPU-S30 Programming Manual .
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 llogical operation instructions each account for 1 words A2ASCPU-S30 Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
