| Product characteristics | |
| 1 | Meet iec61375-1 protocol standard, and support multiple process data port communication; |
| 2 | The MVB communication interface is equipped with redundancy function, which can realize the automatic switching of two channels of MVB communication, and realize the conversion of MVB protocol and UART communication protocol; |
| 3 | Client server mode is adopted. Among them, MVB network card is the server, and user application program is the client. Between MVB network card and user application program, the interface function of process data is called remotely through UART; |
| 4 | The external dimension, power supply mode and communication protocol interface of the network card can be customized according to the user's requirements; |
| Network card-mvb (external) | |
| 1 | External power supply: 110VDC, power: < 5W; |
| 2 | Working temperature range: - 25 ℃ ~ + 70 ℃, meeting industrial standard; |
| 3 | Real time query of port status and update time; |
| 4 | Support multiple process variable ports (source port or destination port, 16-256 bit configurable); |
| 5 | Small volume, 178mm * 110mm * 38mm |
