Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 60k.
Basic command processing speed (LD command) S:0.2.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of Q20UDHCPU Common Instructions Manual Q20UDHCPU Programming Manual Q20UDHCPU
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor.
Light emitting diode two: the input of a photo coupler and the change of electrical signal,
The light signal is generated by the light emitting diode, which is the same as the input signal Q20UDHCPU Common Instructions Manual Q20UDHCPU Programming Manual.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light.
When the switch is off, the diode does not emit light, and the transistor is not on the way Q20UDHCPU Common Instructions Manual Q20UDHCPU Programming Manual. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
Photoelectric three levels: in the light of the light signal conduction, the degree of light signal and the intensity of the light signal.
The output signal has a linear relationship with the input signal in the linear operating region of the photoelectric coupler.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Application: Q series.
Suitable for safety standards: EN954-1 class 4, PLe ISO13849-1.
Security input points: 1.
Add up to 3 additional units: safety relay module.
Use special setting monitoring tools to configure the configuration directly.
Constitute a rich set of components can be easily and quickly set the hardwarre structure Q20UDHCPU Common Instructions Manual Q20UDHCPU Programming Manual.
Creating logic for security devices, by using the automatically generated labels of the FB can easily create logic.
Logical import and export.
You can store the connecttion settings of the input and output modules and the application logic created by the function block as a setting file,
Or read from a saved set file Q20UDHCPU Common Instructions Manual Q20UDHCPU Programming Manual.
