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 Q12PRHCPU PDF.
So, sometimes also known as the order control Q12PRHCPU
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 Q12PRHCPU PDF. 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 Q12PRHCPU PDF.
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 MITSUBISHI Programming Manual .
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 MITSUBISHI Programming Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.Express PCI bus.
Support Japanese, English OS.
Master / local station sharing.
Support Ver.2 CC-Link version.
Province distribution network module in cabinet and device MITSUBISHI Programming Manual .
Link to connect the 64 stations when the fastest scanning time for 1.2ms (rate 2.5Mbps).
According to the transmission distance, the transmission rate is selected from 2 Q12PRHCPU Manual. 5Mbps, 625kbps and 156kbps.
CC-Link/LT from the station does not need any parameter settings.
Only need to set up the transmission speed in the master module, you can use the remote I/O.
I/O control in the first class of open field network module.
CC-Link based on reliable field bus technology,
Able to transmit large number of bits data (such as ON/OFF information) and word data (such as analog information).
Consistency of CC-Link to maintain loop transmission,
And the cycle of transmission and information (instantaneous transmission) communication separately, so as to ensure the timeliness of.
Even if the information reaches saturation, it will not affect the link scan time.
Make the mixed data environment intelligent, to achieve a new manufacturing system IE CC-Link field network module.
Using Ethernet cables and connectors available on the market to reduce costs.
High speed communication capable of communicating with 1Gbps.
Improve the communication response, significantly shorten the cycle time.
Improve the performance of cycle data update. Reduces the transsmission delay time and the application of the synchronization waiting time Q12PRHCPU Programming Manual .
Data can be read or written to other station programmable controller.
Status of IE CC-Link field network can be confirmed by Works2 GX.
Can be in the Workss2 GX up and down the abnormal position, the cause of the exception, the event record,
So it can reduce the time of abnormal to resume normal operation Q12PRHCPU Manual.
