PLC Mitsubishi MELSEC Q Series key features

(1) a wealth of models

Q Series PLC I/O points from 256 to 8,192 points (including remote I/O), the program step number from 8K to 252K of various CPU models, can be divided into basic and higher functions in 2 categories.

(2) ultra-small size

Q Series PLC LSI with advanced BGA technology ASIC,8layer PCB (printed circuit board) 1mm thick, so that the space under the original AnS Series 60%. For example for controlling the 512 I/O or size for all control modules of 8 modules only 328mm (w) x98mm (h) x98mm (d), almost half the size of A4 paper size.

(3) flexible installation

Q Series PLC with 2, 3, 5 slot, 8slot and 12slot a variety of substrates. Without extending the base plate connection module, the base plate can be connected directly using the extension cable. QSeries high performance CPU maximum 7 extends the base board can be connected, using 64 Sockets, the total distance can be extended to 13. 2m。 No power supply module extends the base plate can be used to save space and costs.

(4) double CPU structure

Q Series PLC built-in MSP and two 32-bit RISC processors. MSP (Mitsubishi Se-quence Processor) for Mitsubishi Motors specially developed in order to control processor, including order control processing unit, a floating-point coprocessor, and other peripheral chips, optimal control, essentially improve the conversion efficiency of sequence control program code and processing speed. For example, the indexing operation (for program structure), it does not cause processing delays. So, Q CPU can run fast in the weapons system has been structured with the indexing operation of largecapacity program. In addition, the information and communication done by the RISC processor, so the order of information, communication and control from two processors at the same time, ensuring the fastest and most stable control.

(5) high speed

QSeries high performance CPU instruction execution time for 34ns, executable 10.3 instructions per microsecond, about a series of 5 times times their speed, for QnA series 2.7 times. In addition significantly increased PID and other floating point arithmetic processing capabilities.

(6) with a high speed system bus

Through high-speed of system bus, Q Series CPU and entered output module and simulation volume, and high-speed count, and communications, and network, intelligent of function module Zhijian of data exchange speed has has significantly of improve (and past of compared, about improve has 4~8 times), especially in network module in the for large data exchange of occasions, can do reduced on scan time brings of effect, makes whole system of performance and run speed has significantly of improve.

(7) a plurality of memory

All QSeries CPU (basic and high performance type) configuration program memory, RAM standard and three standard ROM memory. Standard ROM to prevent data loss due to low power possibilities. Without the need for external memory card storage program. QSeries high performance CPU, is equipped with a small PC card slot, the memory card so you can use 32MB. On the storage card, and CPU module can be stored not only all of the soft component annotation file, expand file storage on a storage card. Through special instructions (PLOAD), upload and execute programs from the memory card, virtual extensions to program memory. In addition, stored in RAM memory card program in ROM, ROM memory card or standard, when the system‘s power is switched on, are transferred to the program memory, then the executable (run bootstrap set).

(8) the faster programming port

High performance CPUQ series is configured with a maximum of up to 115. 2kbit/s RS 1232 c programming the mouth, but also equipped with a USB interface. The USB programming port for maximum download speed of 12Mbit/s and 26K procedures and parameters of the write time of 12s. High-speed programming port for faster transmission and monitoring of the program, strengthen adjustment of machine and equipment efficiency.

(9) multiPLC system configuration

Q series can use multiple PLC system configuration where multiple CPU modules can be mounted on the same base unit to manage a different control system I/O and intelligence modules. For example, previously handled by the single CPU module control and information processing in the order can now be performed by different CPU modules in a multiPLC system, not only improves the speed and performance, and scalable applications.
