Product description

WHAT THEY ARE, AND HOW TO GET ONE

Both PROFINET and PROFIBUS devices have unique ID numbers allocated to them to assist with engineering, identification and other issues.

An ID allows devices connected to the bus to be identified with a minimum amount of protocol overhead. In addition, the ID number is used to archive files which contain information on device features and configuration (i.e. GSD or GSDML files).

Getting an ID Number For PROFINET

The Device Identification for PROFINET IO consists of a company key (Vendor_ID) and a manufacturer-specific key (Device_ID). The Vendor_ID is assigned uniquely to a company. The Device_ID can be defined by the manufacturer specifically for the device. PI provides the schemes and the GSDML specification required to create ad GSD-File. PI's GSD-Viewer supports validation and viewing of a GSD-File.

Getting an ID Number for PROFIBUS

An Ident Number (ID number) is required for all PROFIBUS devices using PROFIBUS DP communication (except Master Class 2 devices).

Manufacturers must register each device type with PI and get either a manufacturer and/or profile specific ID number. The ID number is not a serial number. The value range is 0001 Hex to FFFE Hex.

As soon as an ID number for a device type has been assigned to a manufacturer, this number can be used for each manufactured device of this type without renewed registration. If the device is modified technically, it remains associated with the device type only if it is still possible to describe the parameters, modules and options (e.g. modular I/O devices) in a single GSD file.
