GT1055/GT1050/GT1045/GT1040:
User storage capacity: 3MB MR-J4-15KB4
Device USB port.
The standard RS-422/485 and RS-232 interface.
GT1030/GT1020:
User storage capacity: 1.5MB (gt1030) /512kb (gt1020).
Three color LED backlight design, equipment status at a glance.
The standard RS-422/485 or RS-232 interface.
Touch screen, also known as touch screen, touch panel, is a kind of induction type liquid crystal display device can receive contacts and other input signals,
When touching the screen button on the screen,
The tactile feedback system on the screen can drive various connecting devices according to the pre programmed program,
Can be used to replace the mechanical button panel, and by the liquid crystal display screen to create the image of the effect of birth. Input points: 32 points.
Voltage: DC24V.
Current: 8.5mA.
Response time: 10ms.
32 points / a common end.
Positive / negative sharing.
38 point terminal station.
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.
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.
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.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
