RS-232:1 channel, RS-422:1 channel.
BASIC program mode (A3MCPU corresponding): BASIC console interface to use.
Sequential program mode (program controller CPU correspondence): non sequential computer connection interface and use.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc A0J2CPUR23 Manual A0J2CPUR23 Programming Manual A0J2CPUR23 .
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.
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 A0J2CPUR23 Manual A0J2CPUR23 Programming 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. Cable 0.6m for the expansion of the floor, the expansion of a floor for every 1 units.A1SCPUC24-R2 integrates all functions of A1SCPU with a dedicated RS232 interface,
It maintains the compatibility of CPU ANS and is easy to use A0J2CPUR23 Manual A0J2CPUR23 Programming Manual.
The built-in RS232 interface makes it can connect bar code reader, operator interface, computer and so on,
Realization of low cost data communication.
A1SCPUC24-R2 is a combination of A1SCPU and A1SJ71C24-R2 features of the two components together.
It maintains the compatibility and communication specifications for the two component programming.
Fixed this A1SCPU and A1SJ71C24-R2 programming method applied to A1SCPUC24-R2. Self service (IN, OUT): SI optical cable.
Other aspects (IN, OUT): SI optical cable.
Data link anomaly Bureau bypass.
Inter agency extension. For common cathode input module and leaky type output module (2 line type).Terminal row for A2CInput voltage range: AC100 ~ 120V/AC200 ~ 240V.
Output voltage: DC5/12V.
Output current: 2.3A/1.5A.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate.
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 internnal 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 discoonnected from the load A0J2CPUR23 Manual A0J2CPUR23 Programming Manual A0J2CPUR23 Manual A0J2CPUR23 Programming Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
