The BIS M identification system is a contactless read and write system. The read/write device
consists of evaluation electronics with permanently connected read/write head.
The main components of the BIS M identification system are:
– Read/write device,
– Data carrier.

The data carrier is an autonomous unit that is supplied with power by the read/write head. The
read/write head continuously sends a carrier signal that is picked up by the data carrier from
within a certain distance. Once the data carrier is powered, a static read operation takes place.
The processor manages the data transfer between read/write head and data carrier, serves as a
buffer storage device, and sends the data to the controller.
The data is passed to the IO-Link master using IO-Link protocol, and the master then passes it
to the host system.
Host systems may be the following:
– A control computer (e.g. industrial PC)
– A PLC
The BIS M-4_ _-045-… supports cyclical data exchange via IO-Link protocol.
During cyclical data exchange, the BIS M-4_ _-045-… cyclically exchanges read data with the
controller. It is also possible to read or enter parameter data.
