With the bus expansion modules BEM211 a "high speed" connection up to 3 m away is possible (with < 1.5 µs access time) to distributed I/O units. Up to 6 distributed SubDevices can be directly interconnected in a daisy chain topology. Each SubDevice can in turn handle up to 15 M200 standard modules.

The wiring using RJ45 connectors is one advantage of this new technology. Thus wiring is significantly facilitated. A special protocol is not required to use the I/Os with the bus expansion. The user can access these modules directly as if they were local.

 

Features

  • Bus expansion master module with 1 interface
