RS232 connector conversion cable (round connector, 9 pin D-sub connector).
Easy connection through the hub CPU.
By using an Ethernet hub, programming tools and multiple CPU can be connected simultaneously.
Through the programming tool can be searched and displayed in the list has been connected to the CPU Q173DCPU-S1 Communication Protocal.
Therefore, even if the IP CPU address is unknown, just choose from this list, you can easily connect Q173DCPU-S1
Seamless communication without network level constraints.
With the latest high-speed, large capacity IE CC-Link controller network and IE CC-Link field network,
Corresponding to the increasing amount of information.
Together with previous MELSECNET/H, Ethernet and CC-Link,
These networks can be across the network type or level of differences, to achieve seamless communication Q173DCPU-S1 Communication Protocal.
Programmable logic controller on the network through the programming tool of the Ethernet connection,
Monitoring and programming.8 slots.
Requires 1 power modules.
Used to install the old section of the large A series PLC module.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order Q173DCPU-S1 Communication Protocal.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. 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.
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.
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.
Theree exist input / output hysteresis phenomena, i Q173DCPU-S1 Reference Manual. e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation Q173DCPU-S1 Reference Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
