Protocols for position value output
Leuze electronic BPS 8 91
TNT 35/7-24V
9.2 Binary protocol 2 – BPS 8 SM 10x-02
With the BPS Configuration Tool, the user can individually adapt the binary protocols 1
and 6 to the specific requirements of the application. The binary protocols 2, 3 and 4, on the
other hand, have a fixed structure and cannot be modified.

Description
A0 and A1 are the address bits. If several BPS 8 operate in an RS485 network, an address
configuration is required. Every BPS 8 is supplied with the Standard address 0. The
