Appendix F
Supported Emulated Block Transfer
Commands
Appendix Objectives Appendix F provides information about the Emulated Block Transfer
commands supported by the DeviceNet adapter. In this appendix, you
will learn about the following:
• Emulated block transfer commands.
• Emulated block transfer error response.
• Setting up data files for listed emulated block transfer commands.
• Examples of emulated block transfer command.
About Emulated Block Transfer Emulated block transfer is a method used by some SCANport
peripherals to read and write information using PCCC messages.
Some Allen-Bradley DeviceNet products can send PCCC messages.
Other products can send PCCC messages using a DF-1
connection.This appendix assumes that you have experience using
emulated block transfer commands with SCANport peripherals.
Supported Emulated Block Transfer
Commands
The following table lists some supported emulated block transfer
commands and where you can find more information on them.
!
ATTENTION: Hazard of equipment damage exists. If
explicit messages are programmed to frequently write
parameter data to certain drive products, the EEPROM
(Non-Volatile Storage) will quickly exceed its life cycle
and cause the product to malfunction. Do not create a
program that frequently uses explicit messages to write
parameter data to a product. Datalinks do not write to
the EEPROM and should be used for frequently changed
parameters.
