BIS M read/write device, IO-Link device
To ensure that data carriers are detected without error and the data can be reliably read, do not
exceed a maximum distance and maximum offset between the data carriers and read heads
(
see chapter 5 "Technical Data" on page 24 ).
The "distance" value refers to the maximum distance from the data carrier to the sensing surface
of the read/write head.
The "offset" value indicates the maximum offset between the center axis of the data carrier and
the center axis of the sensing surface.
Data carriers can only be reliably detected and the data reliably read within the permissible read
distance and offset.
Data carrier detection is indicated by an LED on the device ("TP – Tag Present",
see chapter 5
"Technical Data" on page 24 ). At the same time, the CP bit is set in the input buffer ("CP
– Codetag Present", see chapter 9.2 "Process data" on page 48 .
