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 A2ASCPU-S30 PDF.
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 A2ASCPU-S30 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 A2ASCPU-S30 PDF.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called thhe host or the basic unit, small, ultra small PLC using this structure A2ASCPU-S30 Manual .
Modular: PLC is the basic components of a separate module A2ASCPU-S30 PDF.
Medium and large PLC used this way. Easy maintenance. DC input points: 16 points.
Input voltage and current: 7mA, DC24V.
Response time: 10ms.
16 point /1 a public side.
Positive / negative sharing.
40 point terminal station.
MITSUBISHI PLC protection and chain procedures MITSUBISHI Programming Manual.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system MITSUBISHI Programming Manual.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc MITSUBISHI Programming Manual. .
MITSUBISHI PLC program simmulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of thee program A2ASCPU-S30 Manual A2ASCPU-S30 Programming Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
