Program memory capacity 14K.
Input and output points to the maximum 512 points.
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh A2ACPU-S1 PDF.
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage A2ACPU-S1 Input and output points: 256 points.
Input / output data points: 256 points.
Program capacity: 6k.
Basic command processing speed (LD command) s:1 A2ACPU-S1 PDF. 0.
Internal storage RAM memory capacity: 16k.
Optical data communication line function with power supply.
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 A2ACPU-S1 PDF. 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.
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 the host or the basic unit, small, ultra ssmall PLC using this structure MITSUBISHI Programming Manual A2ACPU-S1 Manual .
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way MITSUBISHI Programming Manual. Easy maintenance. Cable length: 5 meters.
For connection between GOT and CRT. Input type: DC input, positive common end.
Input points: 8 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/7mA.
Output form: transistor output, leakage type MITSUBISHI Programming Manual.
Output points: 8 points.
OFF leakage current: 0.25mA.
Output protection function.
Rated load voltage / current: DC24V/0.5A.
External connection: /2 line 2~4 line type.
Waterproof connector type.
Strong waterproof type of IP67 protection grade.
No need to stop the system can be replaced module.
Without the use of tools can be a simple connection, save time.
Terminal resistor built-in.
Can be installed along the 6 direction.
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, andd the timeliness is strong A2ACPU-S1 Programming Manual.
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 too guarantee the timeliness A2ACPU-S1 Manual .
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
