Flintec MCS-64 CANbus - Manual (Page 6)

Page Manual MSC-64 6
1 Introduction
1.1 Identification and Scope
This document describes the system design for a CANopen Gateway (CGM85) and up to 64
Load Cell Digitizing Module (LDM88.x) using the Flintec backplane system. It describes the
functionality of the backplane, the protocol used on the backplane and the CANopen profile
used to access the LDM88 modules via the CGM85 Gateway. It specifies the protocols and
logical format of the messages between the CANopen and the local backplane system.
1.2 Purpose
The purpose of this document is to specify functionality and performance of the Gateway and
the Load Cell Digitizing Modules (LDM88) with the available firmware versions (standard
88.183, filling 88.184, loss in weight 88.185).
