Program memory capacity 14K.
Input and output points to the maximum 512 points.
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh.
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage GT1020-LBLW Number of input channels: 8ch.
Input current: DC0 ~ 20mA.
Conversion speed: 1ms/ch.
Resolution: 1/8000.
By shifting the function easily when the system starts to fine tune the movement function GT1020-LBLW.
Shift the set value to (shift to) the function of the digital output value .
If you change the conversion value, the value is reflected in real time to the value of the scale (numeric value),
Can easily complete the fine-tuning of the system startup.
Extended detection method based on usage
Anomaly detection and extension of input signal
The detection method of the abnormal detection function of the input signal can be extended to detect the abnormal detection function of the input signal which is outside the range of the set range GT1020-LBLW.
For the detection of the lower limit or the upper limit of the input signal abnormality, or when the detection of the broken line is performed.
Enter range extension
Range of scalable input range.
Combined with the abnormal detection function of the input signal, the broken line can be easily detected. SI-200/250 fiber optic cable.
Double loop.
Remote station.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the systemm GT1020-LBLW.
MITSUBISHI PLC initiallization procedure . After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program arre:: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc GT1020-LBLW. .
