Conventions & Terminology

The following conventions are used throughout this document:

• Numbered lists provide sequential steps

• Bulleted lists provide information, not procedural steps

• The term ‘user’ refers to the person or persons responsible for installing the Anybus Communi-

cator in a network.

• The term ‘ABC’ refers to the Anybus Communicator.

• Hexadecimal values are written in the format 0xNNNN, where NNNN is the hexadecimal value.

• Decimal values are represented as NNNN where NNNN is the decimal value

• As in all communication systems, the terms “input” and “output” can be ambiguous, because

their meaning depend on which end of the link is being referenced. The convention in this doc-

ument is that “input” and “output” are always being referenced to the master/scanner end of the

link.
