How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc A9GT-70LTTB Manual A9GT-70LTTB User's Manual. .
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps A9GT-70LTTB
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc A9GT-70LTTB Manual A9GT-70LTTB User's Manual. .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined. Input channel number: 4.
Output channel number: 2.
Occupy I/O points: 64.
A1S63ADA analog input / output combination components can be analog / digital / digital / analog conversion,
The input and output signals can be voltage or current,
Offset and gain can be set and stored A9GT-70LTTB Manual A9GT-70LTTB User's Manual.
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.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change off the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the usse of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A9GT-70LTTB Manual A9GT-70LTTB User's Manual A9GT-70LTTB Manual A9GT-70LTTB User's Manual.
This phenomenon is called the I/O delay time effect.
