Communication via the serial interface

All FT50C ...S1 sensors are equipped with a bus-compatible, serial interface (RS485) for bi-directional transmission 
of colour values as well as the setting of sensor functions. The overriding control system controls data exchange. 
Data transfer occurs through an exchange of short telegrams.

• 

This makes it possible to teach-in any number of colours and store them as colour vectors (reference value incl. 
tolerances) in the control system via the interface.

•

  Before beginning the process, the relevant reference colour is transferred back to the sensor. In operating con-

ditions, the sensor compares the actual colour with the reference colour and signals the result to the switching 
output. Repeated teaching of colours is unnecessary.

•

  During on-line access via the RS 485 interface, there are 2 further possibilities:

-  The internally stored colours / colour ranges (max. 5) can be evaluated separately 
-   The actual values can be transferred via the interface. In this case comparison between the actual colour 

and the reference colour is carried out via the control system.

INFORMATION
If several sensors are connected via the RS 485 bus, reflections can occur which may impair 
transmission. The last device in the chain must therefore be fitted with a load resistor (optimum 
value: 120 Ohm).
