Measurement items: leakage current (Io), resistive leakage current (Ior).
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 Q170MSCPU-S1 Special Instructions Manual Q170MSCPU-S1 Programming Manual Q170MSCPU-S1
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 Q170MSCPU-S1 Special Instructions Manual Q170MSCPU-S1 Programming Manual. Alarm monitoring is divided into 2 stages of attention alarm and danger alarm.
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).8 slots.
Requires 1 power modules Q170MSCPU-S1 Special Instructions Manual Q170MSCPU-S1 Programming Manual.
Used to install the old section of the large A series PLC module.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
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 Q170MSCPU-S1 Special Instructions Manual Q170MSCPU-S1 Programming Manual. e., the input / output response delay.
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 Q170MSCPU-S1 Special Instructions Manual Q170MSCPU-S1 Programming Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
