This document is about the Schneider Electric Altivar 61/71 Modbus TCP/IP Daisy Chain Ethernet Card user manual. It provides instructions on how to install and connect the card to an Ethernet network, along with hardware description and connector pinout.
The Altivar 61/71 Modbus TCP/IP Daisy Chain Ethernet card (catalog number VW3 A3 310d) enables an Altivar drive to connect to an Ethernet network using Modbus TCP/IP. It provides full drive functionality such as configuration, control, monitoring, and diagnostics via a standard web server.
The document covers safety precautions, hardware setup, RJ45 connector pinout, network topology guidelines, Ethernet menu navigation, parameter configuration, diagnostics, and software tools. It also includes troubleshooting steps for communication and card faults, as well as information on web server functions and integration with Schneider Electric software tools.
| Catalog number | VW3 A3 310d |
|---|---|
| Transmission speed | Auto detects 10 Mbps or 100 Mbps |
| Duplex mode | Supports half‑duplex and full‑duplex |
| Supported Ethernet frame format | Ethernet II (IEEE 802‑3 not supported) |
| Power supply for daisy‑chain topology | External permanent 24 VDC supply required |
| Shielding connection | Shield connected to drive ground |
A shielded twisted‑pair (STP) Ethernet cable should be used.
Yes, but an external permanent 24 VDC supply is required to keep the network functional if a drive is turned off.
The card automatically detects whether the network operates at 10 Mbps or 100 Mbps.
