Overview
The VW3A3E310D is a Modbus TCP communication card for the Schneider Altivar 61 Plus and 71 Plus drive ranges, operating at 10 or 100 Mbps over a single RJ45 connector in half or full duplex. It carries a Transparent Ready class C20 designation, embedding a web server with data editor, e-mail alerts, Ethernet statistics, FDR agent, Altivar viewer, security IO scanner, and Altivar chart services.
How it compares
The VW3A3E310D uses Modbus TCP over an RJ45 connector; the sibling VW3A3E307 uses Profibus DP over a 9-way female SUB-D connector at rates from 9600 bps to 12 Mbps. Pick the VW3A3E310D when the drive network is Ethernet-based, the VW3A3E307 for a Profibus DP line.
Lifecycle and sourcing
Schneider lists the VW3A3E310D as discontinued. Remaining units are sourced through surplus and broker channels; an RFQ confirms current availability and lead time for the exact card.
