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 QS90SR2SN-EX Safety Application Guide.
So, sometimes also known as the order control QS90SR2SN-EX
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 QS90SR2SN-EX Safety Application Guide.
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 QS90SR2SN-EX Safety Application Guide.
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.
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.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.Connect to read and write 2Ch.
ID system interface module.
ID controller M-688-001/002 BIS can be installed directly to the Q series of substrates,
Control module for reading and writing ID tag data through a programmable logic controller.
The ladder diagram of M-6888-002 BIS is compatible with QD35ID1/2 QS90SR2SN-EX Manual.
2 antennas can be connected, and the parallel processing of the 2 channels can be simultaneously carried out.
Can use all ID tags in the M BIS series.
ID series /BIS system is an industriaal automation ID system which can use the electromagnetic combination method to read and write data QS90SR2SN-EX Manual.
ID tag has a variety of sizes and storage capacity.
