  • High-speed transmission: The transmission speed can reach 100M, which completely solves the inefficiency of traditional 485 communication transmission.
  • Powerful communication: Support 5 SOCKETs, and can be linked with 5 terminal devices at the same time. Support network programming, can download the program from the network.
  • Extensive protocol: It can support both Siemens protocol and MoubusTCP general protocol.
  • Programming is simple: use Siemens S7 protocol, no programming is required. If the ModbusTCP protocol is used, there is a dedicated instruction library.
  • Reliable communication: Designed with EMI anti-interference technology, it can work with the inverter without crashing or dropping the line.
  • Convenient configuration: Support web configuration and PPI programming line configuration.
  • Independent operation: network communication resources operate independently, and do not occupy PPI communication resources.
