Multi-Functional Integrated Gateway GW

　　GW Series

　　The GW gateway operates as an independent system, providing data exchange between communication interfaces with various protocols. Each port can be configured as a master or slave mode as needed for independent operation. It is compatible with various communication protocols such as Modbus RTU, Modbus TCP, ISO1745, and BACnet/IP.

　　The GW gateway is equipped with real-time multi-mask processing, which can be used for data exchange between different communication protocols.

　　Features:

　　- Supports 4 serial ports for upstream or downstream communication (MODBUS RTU, ISO1745)

　　- Supports 1 Ethernet interface for upstream or downstream communication (MODBUS TCP, BACnet/IP)

　　- Multi-channel, multi-tasking capability

　　- Bidirectional transmission and control mode

　　- Real-time system

　　- Quick recovery after restart (e.g., power outage, communication failure)

　　- Supports clock synchronization function

　　- Provides third-party communication protocol customization and development services

　　- Expandable I/O modules for monitoring and controlling digital signals

　　Functionality:

　　1. Cross-System Linkage

　　The GW gateway meets the linkage requirements between different subsystems, such as Siemens CS11, FS720, and FS18 series. Linkage programs are stored within the GW gateway, ensuring the operation of linkage programs even if the upper-level graphic management system fails.

　　2. Protocol Conversion, Synchronous Mode

　　The GW gateway receives requests from control subsystems and, based on protocol requirements, can convert their data and transmit it through different channel interfaces to meet the data format requirements of different third-party systems, such as ISO1745 <-> Modbus RTU.

　　3. Data Sharing, Asynchronous Mode

　　The GW gateway can collect data from different control subsystems to establish a shared database. It can also, according to the protocol requirements of the upper-level management system (such as a comprehensive monitoring system), provide overall integration of system data through polling data read/write functions, such as the BACnet protocol.
