Extended SRAM card 8MB
To record the change of control data without missing.
Data can be collected in a time interval or in a millisecond time interval,
To record the change of the specified control data without any omission.
Therefore, in the event of failure, can quickly determine the cause, the precise action analysis Q00JCPU-E Manual . Measurement items: leakage current (Io), resistive leakage current (Ior) Q00JCPU-E
Measuring circuit number: 2 circuits.
Insulation monitoring module for measuring leakage current.
Leakage current can be measured to ensure safety by monitoring the leakage current (Io), can detect the risk of electric shock.
Insulation state measurement of resistive leakage current (Ior) can be monitored continuously and continuously,
In order to continuously monitor the insulation aging status of the equipment Q00JCPU-E Manual .
Each measurement project can be carried out in the 2 phase of the alarm monitoring can be respectively on the leakage current (Io), resistive leakage current (Ior) for the 2 phase of the alarm monitoring,
No ladder diagram program. Alarm monitoring is divided into 2 stages of attention alarm and danger alarm Q00JCPU-E Manual .
A module can measure two circuits of a module can be two circuits on the same line in the same system type power measurement.
In addition, Works2 GX (1.90U version or higher version) can be used to easily set the parameters.
Leakage current (Io), resistive leakage current (Ior) MITSUBISHI Q00JCPU-E Programming Manual. Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 60k MITSUBISHI Q00JCPU-E Programming Manual.
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 MITSUBISHI Q00JCPU-E Programming Manual.
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.
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. 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 meeasure of how much the user application can store the number of indicators Q00JCPU-E Structured Text.
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 llogical operation instructions each account for 1 words Q00JCPU-E Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
