Input and output points: 4096 points.
Input / output data points: 8192 points.
Program capacity: 124k.
Basic command processing speed (LD command) S:0.075.
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 QD77MS16 datasheet QD77MS16
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 QD77MS16 datasheet.
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 QD77MS16 datasheet. 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. MES interface module.
Need MX MESInterface software and CF card.
Easily connect production equipment and information system.
Through the excellent database sharing function, greatly reduce the cost of information.
By direct connection, the connection process of the enterprise system database (such as MES) is simplified.
Module configuration is simple, without any programming.
The data can be monitored in the module side, when a user defined trigger condition occurs,
Will be read in the form of SQL text and send the specified data to the MES.
The network load can be reduced commpared with the previous scheme which is based on the gateway PC to obtain / monitor the data QD77MS16 PDF datasheet.
Receive information from the MES, perform pre stored SQL tasks.
In addition, the production instructions from the MES are also receeived,
The production information can be downloaded from the database, and the modification of the formula information can be conveniently carried out QD77MS16 PDF datasheet.
