Input points: 32 points.
Voltage: DC12/24V.
Current: 4/10mA.
Response time: 10ms.
8 points / a common end.
Negative utility.
38 point terminal station.
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 MR-J2S-20B
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.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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. Output points: 32 points.
Output form: source type.
Rated output voltage: DC12 ~ 24V.
Max load current: 0.1A/1 point.
Protection function: have.
Common way: 32 point / public end.
Input / output occupied points: 32 points (I/O distribution: output 32 points).
External wiring connection mode: 40 pin connector.
The switch input and output module is a device which can collect the input / output of the switch signal,
Digital I/O modules are often called.
The switch signal is collected to the computer or the computer to send the relevant instructions through the RS-485 bus to control the switch of the switch,
Can also be carried out through the RS-485 bus communication,
Remote control switch.
Communication protocol is a standard Modbus protocol or custom protocol.
