Identification

This interface document SAE J2286 revises the requirements for file formats as were originally described in SAE J1924. This document describes Interface 1 (I/F 1) in SAE J2461. This document does not imply the use of a specific hardware interface, but may be used with other hardware interfaces such as SAE J1939, ISO 15765 or ISO 14229. The requirements of SAE J2286 supersede the requirements defined by SAE J1924.

Introduction

SAE J2461 establishes the requirements for Interface 1 (I/F 1), as a replacement of the file-based interface described by SAE J1924, as shown by Figure 1. Interface 1 (I/F) is a bi-directional link between the OEM Shop Floor Program (CSCI 1) and the Vendor Component Program (CSCI 2). Using I/F 1, the OEM Shop Floor Program communicates the desired parameters and programming limits for an assembly job to the Vendor Component Program (VCP). In response, the VCP returns programming results to the OEM Shop Floor Program (CSCI 1).

I/F 1 maintains the file structures described in SAE J1924 as closely as possible. The parameter file setup record was changed to reflect the common means communication provided by CSCI 3, the communication Device Driver. A new record type was added to better define how data files, external to the parameter file, would be used. This clarifies SAE J1924 by clearly defining whether the parameter value string 123.123 refers to a numeric value or a filename.

Besides correcting errors, other changes to SAE 1924 include:

a. Deletion of tattletale records

b. Better descriptions of fields and records

c. An additional field in a Definition File record

d. Directory structure and file naming conventions supporting future growth

e. VCP command line content and file directory structure
