Introduction

What’s in this Chapter?

This chapter describes how the INTERBUS master sets up communications with an Advantys STB island and the network parameterization, configuration and diagnostics services performed to configure the island as an INTERBUS node. To communicate with an Advantys STB island, the INTERBUS master sends output data across its network to the STB NIB 1010 basic NIM. The NIM transfers this output data across the island bus to the destination output modules. The NIM collects input data from the island’s input modules and sends the data back to the fieldbus master in a bit-packed format.
