MODBUS RTU/MODBUS ASCII Master slave station.
RS-232.
RS-422/485.
MODBUS interface module capable of connecting MODBUS compatible device such as temperature regulator, measuring device and so on Q04UDVCPU PDF.
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 Q04UDVCPU
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 Q04UDVCPU PDF.
The RS-232 interface (1 credit on the 1 pass) MODBUS master device with multiple MODBUS communication from the station equipment. (only QJ71MB91)
Master / slave station functions can be used simultaneously. (only QJ71MT91)8 channel Q04UDVCPU PDF.
Input: DC4~20mA.
Output (resolution): 0~6400; 0~3200.
Conversion speed: 10ms/ channel.
18 point terminal station.
Isolation between channels.
Power supply to a two wire transmitter.
The possibility of expanding control with intelligent function.
At the same time, the channel isolation analog module realizes high isolation voltage,
Further improve the accuracy of the benchmark MITSUBISHI Programming Manual .
Provide support for process control using a general purpose programmable controller.
Flow meter, pressure meter, other sensors can be directly connected to analog input,
Control valve can also be directly connected to analog output MITSUBISHI Programming Manual .
Hardware and installation costs have been greatly reduced due to the need for an external isolation amplifier.
High insulation strengtth Q04UDVCPU Manual.
Can isolate electrical interference, such as current and noise, etc..
Standard analog input module.
Isolated analog input module.
No external isolation amplifier required MITSUBISHI Programming Manual .
Without the use of inter channel isolation analog modules.
Using the inter channel isolation analog module."The most common station 11 units connected network: 121.
The 11 largest network connection units security station: 32.
Maximum network number: 239 sets.
Maximum secure connection of 1 units: 31 connection.
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 outsidde the standard control procedures Q04UDVCPU 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 Q04UDVCPU Manual. "
