16 channels.
DC-10 ~ 10V, DC-20 ~ 20mA.
38 point terminal station.
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points MITSUBISHI FR-PA07.
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book FR-PA07 The number of output channels: 4 channels.
Voltage output: DC-10~10V.
Current output: DC0~20mA, DC-4~20mA.
Programmable logic controller: FX2NC, FX3UC.
By using analog input module and output module,
Can be input and output analog (voltage, current, etc.).
Indispensable analog control in FA control,
It is easy to implement on a programmable logic controller MITSUBISHI FR-PA07. Input and output points: 480 points .
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DAC100 ~ 120/200 ~ 240V/ output 2A DC24V, 0.5A DC5V.
Optical data communication line.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
User program storage cappacity: it iis a measure of how much the user application can store the number of indicators FR-PA07.
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 lloggical operation instructions each account for 1 words FR-PA07. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
