Function

In modern machines and systems, binary sensors and actuators are connected together via AS-Interface.

Until now it was necessary to go back to the use of costly conventional wiring when wanting to use absolute encoders. The reason for this was that the handshake mode with the control module of the analogue profile proved to be too slow for positioning tasks.

In order to meet the real-time demands of many applications, a multi-slave solution using the BSM58 AS-Interface rotary encoders was created. The position value of 16 Bits in length is transferred within a single cycle via the 4 integrated AS-Interface chips to the master and made available to the PLC.

The absolute encoder is mounted directly onto the application shaft, without any coupling. Rotation of the absolute encoder is prevented by a torque rest. This may simply be a slide-in pin that locks in the plastic receptacle integrated into the flange.
