ATV61 Process Image

Introduction

This topic discusses the input and output data process image for the ATV61 drive.

NOTE: The following data format is particular to the island bus and ignores the

fieldbus on which the island is operating. The data is transferred to the master in a

fieldbus-specific format. For fieldbus-specific descriptions, refer to one of the

Advantys STB Network Interface Module Application Guides. Separate guides are

available for each supported fieldbus.

Input Data

Data from each input module on the island bus is represented in the NIM’s input data

process image, a reserved block of 4096 (16-bit) registers in the range 45392 to

49487. The ATV61 drive sends a representation of the operating state of the drive

and the attached motor to the island’s NIM. The NIM stores the information in two

contiguous 16-bit registers. (The specific positions of the registers in the process

image are based on the module’s node address on the island bus.) The input data

process image can be read by:

 the fieldbus master

 an HMI panel connected to the NIM’s CFG port

 the Advantys configuration software in online mode

For more information about each data word in the process image, see:

 ATV61/71 CANopen User’s Manual (1755865)

 ATV61 Communication Parameters Manual (1760661)

 ATV61 Programming Manual (1760649)

Output Data

The NIM keeps a record of output data in one block of registers in the process

image. Information in the output data block is written to the NIM by the fieldbus

master or by the Advantys configuration software in online mode (if the island is in

Test mode). The ATV61 drive uses two registers in the output process image.

The NIM’s output data process image is a reserved block of 4096 (16-bit) registers

in the range 40001 to 44096 that represents the data sent by the fieldbus master.

Each output module on the island bus is represented in this data block. The ATV61

drive uses two contiguous registers in the output data block. (The specific positions

of the registers in the process image are based on the module’s node address on

the island bus.)
