TCP Client mode:
In TCP Client mode, the module after power settings according to their own initiative to connect TCP Server server, and then establish a long connection, after the data transparently. In this mode, IP TCP Server module needs to be seen through visible means IP PING module where you can directly through the server IP, the server may be fixed IP Internet, and modules can also be the same local area network IP .
TCP Server mode:
In TCP Server mode , the module first attempt communication with the gateway, and then set the local port monitor, respond and create a connection when there is a connection request, up to four links exist simultaneously , after the serial data received is sent to all network simultaneously module to link devices.
In UDP mode, the port on the module after power monitor settings, do not take the initiative to establish a connection, when there is data from through the pass over, forwarded to the serial port, serial port when receiving data sent to the module to set the IP port over the network.
UDP Server mode:
UDP Server is defined on the basis of ordinary UDP does not verify the source IP address, UDP packet is received after the destination IP to the data source IP, TCP Server functions similarly. In this mode, the module default recording a target IP, when the serial data to IP to send data records, while the status of the module is the server, the network accepts packets sent to the module, and any time to adjust the target IP as a data source The IP, suitable for multi-mode operating mode corresponding IP. Use the computer end of the program and UDP mode exactly the same, no need to change.
1, networking firefighting systems
using conventional fire fighting system 485 or CAN bus, there is a node expansion inconvenient, poor system stability, maintenance inconvenient, easy false malfunction shortcomings. Use Ethernet networking module program, you can control all sensors and networking, to achieve stable and reliable automatic fire alarm and fire control system, all data through one or more servers unified management, real-time view of data and storage management convenient, stable and reliable.
2, smart grid monitoring
grid is the relationship between people's livelihood security and vital equipment, through the grid monitoring device networking, network remote observation and control various monitoring points, can help power the real-time operating personnel to understand current of each monitoring point on the line, the voltage changes , short circuit, grounding, disconnection, insulation and other faults or anomalies fall in line next to the sound and light alarm or SMS notification, inform the commissioning personnel to remotely operate and transfer power to isolate the fault, notify the electricity to run the personnel rushed to the scene for processing .
3, the elevator control system
related to the operation of the elevator safety of passengers, elevator manufacturers, property operators, safety regulators are eager to be able to run real-time and accurate understanding of the state under the jurisdiction of the elevator, the elevator main controller by reading data, real-time operating data of the elevator to the network server, real-time display and storage, and in the light alarm and alert people to maintain different levels of users have different permissions, to achieve efficient management and reduce the occurrence of accidents , the accident occurred during playback.
4, temperature and humidity measurement and control system
for temperature and humidity parameters in sensitive areas vegetable greenhouses, farms, drug warehouses, tobacco warehouses, electrical storage, ammunition depots, etc., the need for real-time monitoring of temperature and humidity control, temperature and humidity sensors by and fan, heating devices, humidifiers and other devices networked temperature and humidity data can be transmitted to one or more servers, real-time monitoring data storage and the flexibility to set the start and stop conditions for each controller, temperature and humidity reach intelligent monitoring manual and automatic control, ensure production and life and property safety.
5, intelligent engine room monitoring
room monitoring system for each region to monitor temperature and humidity, room all power equipment, such as high-voltage power distribution, low voltage distribution, diesel generators, power distribution cabinets, UPS, DC power systems, batteries and other air conditioning equipment monitoring, video surveillance images, leakage monitoring systems, intelligent access control, fire system monitoring, through serial device networking module, the original serial devices all through the unified network management, high intelligence, high reliability, maintenance and use simple .
6, industrial control systems
use more traditional PLC RS232 and RS485 communication, to meet the needs of large-scale intensive management, can be transferred through the network serial port module, the unified management of industrial equipment, networking, remote IO control, data acquisition, process monitoring, to achieve higher efficiency. PLC at home and abroad has been widely used in steel, petroleum, chemicals, power, building materials, machinery manufacturing, automobile, textile, transportation, environmental protection and cultural entertainment and other industries, there is a very wide range of applications to PLC networking.
