Single- and multi-turn encoders with Modbus/TCP Interface

Click2Contact

The absolute rotary encoder is able to provide three different kinds of output data: the position value, a velocity value and a time stamp. These can be use in arbitrary combinations for TCP transmitting.

The encoder has a maximum resolution of 65,536 steps per revolution (16 bit). The Multi-Turn version can detect up to 16,384 revolutions (14 bit). Therefore, the largest resulting resolution is 30 bit = 230 = 1,073,741,824 steps.

The encoder supports the communication with Modbus/TCP-PLCs and -IPCs. With function code 03 the user can read out data. Function code 16 allows the user to set the parameters.

There is no specific software required for version A1 to initiate and use the absolute rotary encoder because the sensor can be read out and programmed by any standard web browser. For this purpose the absolute rotary encoder contains a web server, which provides HTML documents with embedded Java applets.
