Introduction
This chapter describes how the INTERBUS master sets up communications
between itself and an Advantys STB island bus. The chapter describes the
parameterization, configuration, and diagnostics services that are performed in
order to configure the island bus as a node on an INTERBUS network.
To communicate with an Advantys STB island, the INTERBUS master sends output
data across its network to the STB NIB 2212 INTERBUS NIM. The NIM transfers
this output data from the master across the island bus to the destination output
modules. The NIM will collect input data from the island bus I/O modules. That data
is transmitted in bit-packed format over the INTERBUS network to the fieldbus
master.
