Wago's RS-232/SMI interface is part of their family of building automation components and makes uniform control and communication of SMI-compliant electrical drives possible. This DIN-rail mountable interface module controls up to 16 SMI blind/shutter drives. It supports the full range of SMI functions, including open/close and stop commands, moving to any position, slat angle adjustment and motor/blind position feedback. An I/0-System controller, a serial interface and an SMI interface module perform the communication. A standard bus system is used to link SMI functions, allowing central commands to be received by the controller and transmitted to the drives via SMI interface. The controller transmits SMI drive's status information to a higher-level building management system. SMI function configuration is performed via specialty WAGO-I/O-PRO function blocks on the controller.
