MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations A6CON-P214 PDF datasheet .
MITSUBISHI PLC initialization procedure A6CON-P214 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 are: 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 A6CON-P214 PDF datasheet . .
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation A6CON-P214 PDF datasheet . Cable 0.6m for the expansion of the floor, the expansion of a floor for every 1 units.3C-2V/5C-2V coaxial cable.
Single bus.
PC inter network (management station / common station) / remote I/O network (remote control station) MITSUBISHI A6CON-P214 PDF catalog.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc MITSUBISHI A6CON-P214 PDF catalog. .
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 MITSUBISHI A6CON-P214 PDF catalog.
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..
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. Temperature sensor: PT100, 3 wire system.
The A1S62RD3 and A1S62RD4 temperature sensor input modules allow the platinum resistance temperature sensing element to be directly connected to the PLC,
This component converts a signal from a temperature measuring element to a numeric value that represents a temperature measurement value,
This temperature value can be used for the control process.
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 ttime of the change of 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 A6CON-P214 PDF datasheet A6CON-P214 datasheet.
This phenomenon is called the I/O delay time effect.
