Data format: RTU.
Data bits: 8.
A1SJ71UC24-R2-S2 and A1SJ71UC24-R4-S2 allow the Ans series PLC to be connected to the MODBUS network,
As the network from the station, and in accordance with the instructions of the main station of the CPU Ans user storage area for data reading / writing.
In addition to supporting the MODBUS protocol, these components also support the standard dedicated communication protocol for A1SJ71UC24 components A6TE2-16SRN User's Manual
A6TE2-16SRN
This feature makes the main station of the data acquisition and control with more flexibility.
Support MODBUS slave station protocol.
Supports 1 to 21 function code.
Two transmission modes: RTU or ASCII. 32: terminal line adapter 0.3mm2 (AGW22).Self service (IN, OUT): SI optical cable A6TE2-16SRN User's Manual.
Other aspects (IN, OUT): SI optical cable.
Data link anomaly Bureau bypass.
Inter agency extension.
Cable transformation. Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command): with 1 s coaxial data communication line function.
Each scanning process. Focus on the input signal sampling A6TE2-16SRN User's Manual. Focus on the output signal to refresh.
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 MITSUBISHI A6TE2-16SRN Manual.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program MITSUBISHI A6TE2-16SRN Manual.
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 MITSUBISHI A6TE2-16SRN Manual. e., the input / output response delay.
User program storage capacity: it is a measure off how much the user application can store the number of indicators A6TE2-16SRN .
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 A6TE2-16SRN User's Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
