3500/92 Function Description
For 10BASE-T star configuration Ethernet, the 3500/92 Ethernet connection is an RJ45 connection. In addition to the main value Modbus register, the 3500/92 supports the communication interface, communication protocol, and additional features of the original 3500/90. The primary value Modbus repository in 3500/92 was replaced by the configurable Modbus repository utility, which now provides the same functionality.
Energy consumption
● The typical value when using the ModbusRS232/RS422 I/O module is 5.0 watts
● The typical value is 5.6 watts when using the Modbus RS485 /O module
3500/92 data type
Use a high-speed internal network to collect information from other modules in the rack, including time-stamped current measurements, module status, and current alert status.
● The exact data type returned depends on the channel configuration and module type.
Update time: The data acquisition rate for all modules in the 3500 rack will not be greater than 1 second, depending on the rack design.
Communication gateway module is a kind of intermediate equipment to realize network interconnection, which can realize data conversion and transmission between different types of networks, so that different types of networks can communicate with each other.
The communication gateway module usually has the following functions:
Data conversion: The communication gateway module can convert the data formats and protocols of different types of networks so that devices between different networks can communicate with each other.
Data transmission: The communication gateway module can transmit data between different networks in order to achieve data sharing and transmission.
Routing: The communication gateway module can select the best route based on the network address or other parameters, so that the data can be transmitted to the destination address faster and more accurately.
Network security: The communication gateway module is able to protect the security of the network against unauthorized access and data leakage. It can achieve security protection through firewall, encryption technology and other ways.
Network management: The communication gateway module can manage and monitor the network in order to discover and solve network faults in time to ensure the stability and availability of the network.
In short, the communication gateway module is an important device to realize the interconnection between different types of networks, which can realize the functions of data conversion, transmission, routing, network security and network management, so that various types of networks can communicate with each other, and realize the sharing and transmission of data.
The process of communication gateway module to realize data conversion usually includes packet recombination and decomposition, as well as specific protocols to encode, decode and compress data in different formats.
Packet reassembly: The communication gateway reassembles packets that do not meet the requirements of the local network. This is achieved by dividing long packets into smaller packets for easy transmission and reassembly.
Packet decomposition: The communication gateway also needs to divide the received packets into smaller packets, a process called packet decomposition.
Data encoding, decoding and compression: In order to realize the conversion of data in different formats, the communication gateway module will use a specific protocol to encode, decode and compress the data. These processes can convert data from one format to another for easy transfer and sharing across different networks.
In general, the communication gateway module realizes the data conversion and transmission between different types of networks through the above steps.
