Schneider has marked this card obsolete — no direct replacement from the factory. ## What the BACnet card actually does on the network It supports BACnet standard profile B-ASC with read/write property requests, plus binary inputs, analog inputs, binary outputs, analog outputs, and binary values — covering the objects a BMS needs to monitor and command the drive. Transmission rate is configurable from 9.6 to 76.8 kbps, matching typical MS/TP bus speeds in HVAC and process building networks. The physical connection is a 4-way removable screw terminal block — standard for daisy-chaining the RS-485 bus through the drive enclosure. ## Diagnostic feedback for commissioning and fault finding Two LEDs on the card face: one green COM LED for data exchange activity, one red ERR LED for fault indication. The graphic display terminal also shows valid and invalid frame counters — useful during BACnet bus commissioning to spot wiring or baud-rate mismatches.","metaTitle":"Schneider Electric VW3A21315 BACnet Communication Card","metaDescription":"Schneider Electric VW3A21315 BACnet communication card for ATV212 drives.
