Cable 3M for the expansion of the floor, the expansion of a floor for every 1 units.10BASE2.
When communicating in the PLC network of MITSUBISHI,
There is no sense of difference and discontinuity in the network,
Can carry on the remote monitoring, modification, debugging and other work of data communication and program,
Without taking into account the level and type of network MITSUBISHI A6PHP.
MELSECNET/H and CC-Link use the way of loop communication,
Periodically automatically send and receive messages,
Does not require specialized data communication procedures,
Simple parameters can be set A6PHP
MELSECNET/H and CC-Link are used to transmit and receive the broadcast mode,
This can be done on the network data sharing MITSUBISHI A6PHP.
For the use of Ethernet, MELSECNET/H, CC-Link network,
Can set the network parameters and various functions, simple and convenient in the Developer GX software screen. Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
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 small PLC using this structure MITSUBISHI A6PHP.
Modular: PLC is the basic components of a separate module MITSUBISHI parts.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh MITSUBISHI parts.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh MITSUBISHI parts.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a mmeasure of how much the user application can store the number of indicators A6PHP.
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 MITSUBISHI A6PHP. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
