Input points: 8 points (dual input), 16 points (single input).
Isolation mode: photoelectric coupling.
Rated input voltage: DC24V.
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 QJ71C24N-R2 Application Manual QJ71C24N-R2 User's Manual QJ71C24N-R2
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 QJ71C24N-R2 Application Manual QJ71C24N-R2 User's 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 QJ71C24N-R2 Application Manual QJ71C24N-R2 User's Manual. 8 modules can be installed.
Input / output points: 256 points.
Number of input and output elements: 8192.
Program capacity: 10K step.
Processing speed: 0.12 s.
Program memory capacity: 40 KB.
Support USB and RS232.
Unable to install memory card.
Own floor 8 slot.
Ultra high speed processing, production time is shortened, better performance.
As applications become larger and more complex, it is necessary to shorten the system operation cycle time.
The operation period can be shortened by the super high basic operation speed 1.9ns.
In addition to achieve in the past with the control of single-chip high-speed control,
The system performance can be improved by reducing the total scan time,
To prevent any possible performance bias.
High speed and high precision data processing.
The processing speed of the real number (floating point) arithmetic hhas been greatly improved,
Addition instruction reached 0 QJ71C24N-R2 Application Manual QJ71C24N-R2 User's Manual. 014 mu s,
Therefore, it can support the request of high-speed, high-precision processing data processing.
In addition, the new additioon of double precision floating point arithmetic instructions,
Simplify the programming, reduces the computational error when executing complex formula QJ71C24N-R2 Application Manual QJ71C24N-R2 User's Manual.
