Core Network Function and System Role
The GE Fanuc IC670PBI001-BE is a PROFIBUS Bus Interface Unit for distributed I/O systems. This module enables high-speed data exchange between a host CPU and remote Field Control I/O. It effectively implements a distributed I/O architecture via a standard PROFIBUS DP network. Consequently, it enhances system flexibility and reduces wiring complexity in industrial automation.
Key Connectivity and Configuration Features
This interface unit provides two dedicated 9-pin D-sub connectors for network and programming tasks. It supports a wide range of standard PROFIBUS data transmission speeds up to 12 Mbits. An integrated array of eight DIP switches allows easy node address configuration from 00 to 32. Furthermore, it can host and manage up to eight Field Control I/O modules from a single network node.
Detailed Technical Specifications
Designed for reliable 24VDC operation, the module mounts to a dedicated Bus Interface Unit terminal block. This design facilitates both DIN rail and panel mounting in control enclosures. The following table summarizes its critical technical and operational parameters.
