A171SCPU CPU unit

A1SD51S is an intelligent communication module used in ANS series,
Can use the AD51H-BASIC language to make online or offline programming on the universal terminal or computer,
Multitasking can also be performed with up to two programs at high speed.
PLC is the use of " sequential scanning, and constantly circulating " way to work A171SCPU.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work A171SCPU A171SCPU

Extending cable to connect CPU main substrate and extended substrate,
According to the model can provide different cable length,
If you need to connect the AnN type expansion substrate is required,
Selection of A1SC05NB (A1SC07NB) cable. I/O points: 512.
Processing speed: sec/ 0.2u step.
Memory capacity: 64K bytes.
Program capacity: 14K step.
With the rapid development of microprocessor, computer and digital communication technology,
Computer control has been extended to almost all industrial fields.
Modern society requires manufacturing to respond quickly to market demand,
Production of small quantities, multi varieties, multi specifications, low cost and high quality products,
In order to meet this requirement,
Production equipment and automatic production line control system must have high reliability and flexibility,
PLC programming is to comply with the requirements of the emergence of it is based on a microprocessor based general industrial control device.
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments.
It uses programmable memory,
An instruction used to perforrm logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process A171SCPU.
Programmable controlller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions A171SCPU.
