Abstract
The present invention works in combination with an integrated set of hardware and software tools that support rapid design, programming, debugging, implementation, and testing of local operation network local operation network nodes and applications. These hardware and software tools speed development by enabling developers to use object-oriented concepts, such as network variables and input/output objects, rather than low-level constructs. The development environment operates with an IBM PC/AT or compatible computer and can grow from a single emulated application node to a completely distributed system of up to 24 emulated nodes and hundreds of remote nodes. The invention is mainly directed to a repeater circuit which is part of a control processor board, and is used to send and receive the serial signals between the PC and connected development stations, and the serial data protocol which enables the development stations to be automatically configured at system start-up. The automatic configuration capability avoids the necessity of manually configuring aerial devices on a network so that each has a unique address.
