Input / output points: 256 points.
Program capacity: 8 K step.
Processing speed: 0.2 s.
Built in communication port: RS232*1.
Continue to go beyond, to climb the peak of Q series.
Strengthen security function.
Can be set up to 32 characters of the file password.
In addition to the English letters, numbers, but also the use of special characters,
To further enhance the security of the password QS90SR2SN-EX Safety Guideline QS90SR2SN-EX
In addition, only pre registered devices are allowed to access CPU,
To intercept unauthorized access to unauthorized users.
Therefore, it is important to prevent the outflow of important program assets and protect intellectual property rights.
CPU module expansion standard RAM (max 8MB).
Can be used with the SD memory card at the same time QS90SR2SN-EX Safety Guideline.
Continuous access file register.MODBUS/TCP Master slave station.
10BASE-T/100BASE-TX.
MODBUS interface module capable of connecting MODBUS compatible device such as temperature regulator, measuring device and so on.
Support MODBUS communication function, and can be compatible with the third party MODBUS to communicate from various station equipment.
Support MODBUS communication functions from the station, can communicate with the third party programmable controller MODBUS master device QS90SR2SN-EX Safety Guideline.
Through the linkage function, the master can be connected to the CH1 side (RS-232),
And through the QJ71MB91 and connected to the CH2 side (RS-422/485) of a number of stations for communication MITSUBISHI QS90SR2SN-EX Manual.
The RS-232 interface (1 credit on the 1 pass) MODBUS master device with multiple MODBUS communication from the station equipment MITSUBISHI QS90SR2SN-EX Manual. (only QJ71MB91)
Master / slave station functions can be used simultaneously. (only QJ71MT91)Input points: 8 points (dual input), 16 points (single input).
Isolation mode: photoelectric coupling.
Rated input voltage: DC24V MITSUBISHI QS90SR2SN-EX Manual.
Output points: 4 points (select the source type + drain type), 2 points (when selecting the source type + source).
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.
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 standaard control procedures QS90SR2SN-EX .
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 memoryy,
Output is only when the processing result is in full agreement,
If any inconsistency occurs during the process, the system is immediately shut down QS90SR2SN-EX Safety Guideline.
