    Protocols for position value output Binary protocol 3 – BPS 8 SM 10x-03 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.
  • Page 101 Protocols for position value output A0 and A1 are the address bits. If several BPS 8 operate in an RS 485 network, an address configuration is required. Every BPS 8 is supplied with the Standard address 0. The address assignment (Default: 0) is performed using the BPS Configuration Tool (see chapter 8.5.3 "Communication").
