1. GENERAL DESCRIPTION
1.1 INTRODUCTION
The optional Digital General Function Card (DGF) is mounted on the AV300i drives
for special functions such as winder/unwinder control, positioning, etc. It connects
with the drive regulation card via the connector for an optional card. The connection
with the drive also provides the power supply for the DGF.
The communication between the two cards uses a 2Kbytes dual-port ram (DPRAM).
The 6KCV301DGF card is based on an Intel 80C386EX-25 with a numerical processor
80C387SX-25.
The standard user communication on the card is RS-485 serial link.
It is possible to mount an option module with CAN controller for DeviceNet
communication.
It is also possible to read and write DGF parameters using all the drive communications
[serial link, local keypad and an additional optional communication card (e.g. GENIUS,
INTERBUS-S or PROFIBUS-DP)]. All these communications use the drive
microprocessor and DPRAM.
This manual comprises four chapters:
- Chapter 1 describes the DGF hardware. Its installation and configuration settings
are detailed. Settings for serial communications are explained.
- Chapter 2 details the software architecture of the DGF. It describes the MARTE
operating system, task organization, DGF parameters and variables, the five card
status states, and the DGF alarm conditions. Permissible data formats are described.
Drive keypad programmer operation is also described.
- Chapter 3 describes the HIBS software, which is used to download compiled user
programs to the DGF Card ; it is also used to load .BLK files (explained in chapter
4) to create supervision pages to monitor drive operation.
- Chapter 4 details .BLK file syntax. The .BLK file is an ASCII file which is used
to configure DGF DPRAM (Dual-Ported Random Access Memory) and create
supervision pages.
