Control mode: loop program execution.
Input / output control mode: refresh mode.
Programming language: ladder diagram, function block.
Processing speed (CIS): 0.10 s.
Program capacity: 14k step.
Security PLC (secure programmable system) refers to the self or external components or the implementation of the failure of the agency,
Can still respond to and promptly cut off the output of the programmable system Q26UDHCPU Application Functions Manual Q26UDHCPU Strctured Programming Manual Q26UDHCPU
Different from ordinary PLC, security PLC not only can provide the function of ordinary PLC,
Safe control function can be realized,
Meet the requirements of the ISO 13849-1 EN and IEC 61508 control system safety related component standards.
PLC security market mainstream has oilz (Pilz) PSS 3000, PSS 4000,
PSS 4000 in addition to the security process can also be processed outside the standard control procedures Q26UDHCPU Application Functions Manual Q26UDHCPU Strctured Programming Manual.
All the components in the security PLC adopt the redundancy structure,
Two processor processing for cross detection,
The processing results of each processor are stored in their respective memory,
Output is only when the processing result is in full agreement,
If any inconsistency occurs during the process, the system is immediately shut down Q26UDHCPU Application Functions Manual Q26UDHCPU Strctured Programming Manual. Input and output points: 512 points.
Input / output data points: 8192 points.
Program capacity: 28k.
Basic command processing speed (LD command) S:0.2.
PLC in the program execution stage: according to the order of the user program order to store the order of each instruction,
After the corresponding operation and processing, the result is written to the output status register,
The contents of the output status register are changed with the execution of the program.
Output refresh phase: when all instructions are executed,
The output status register is sent to the output latch in the output refresh stage,
And through a certain way (relay, transistor or transistor) output, drive the corresponding output equipment. Extended SRAM card 1MB.
Support SD memory card.
High speed universal QCPU support SD memory card,
In order to be able to have a memory card port between SD and PC to easily realize data exchange.
In addiition, the SD memory card and the extended SRAM card can be used simultaneously Q26UDHCPU Application Functions Manual Q26UDHCPU Strctured Programming Manual.
Therefore, the extension of the file register using the extended SRAM card,
SD memory cardd can be used at the same time to carry out the data file record, a large number of annotation data storage, through the memory card to guide operation Q26UDHCPU Application Functions Manual Q26UDHCPU Strctured Programming Manual.
