It supports BACnet MS/TP Slave, MODBUS ASCII/RTU, and UD Link (user-defined) protocols across a baudrate range from 1,200 to 460,800 bps. The feed-through terminals with spring plugs allow daisy-chain wiring without additional junction blocks, which simplifies panel layout and reduces termination points. The built-in 120 ohm termination resistor is enabled via a DIP switch — no external resistor pack is needed. For RS-485 networks, termination should be enabled only on the two end devices; the switch simplifies compliance with this requirement. The module communicates over the DVP-S backplane, so no separate power supply is required beyond the PLC base unit. ## Protocol & Baudrate Coverage The DVPSCM52-SL supports BACnet MS/TP Slave, making it suitable for building automation integration (HVAC, lighting, access control) where BACnet is the fieldbus standard. MODBUS ASCII/RTU covers legacy and modern SCADA connections, while UD Link provides a user-defined protocol for custom device communication. The baudrate range from 1,200 to 460,800 bps covers slow twisted-pair runs (1,200–19,200 bps) through to high-speed links (115,200–460,800 bps) typical for short, well-terminated RS-485 segments.","metaTitle":"Delta DVPSCM52-SL RS-485/422 Module, BACnet & MODBUS, Curren","metaDescription":"Delta DVPSCM52-SL serial communication module, RS-485/422, BACnet MS/TP Slave, MODBUS ASCII/RTU, UD Link.
