Appendix F
Supported Emulated Block Transfer
Commands
Appendix F provides information about the Emulated Block Transfer
commands supported by the EtherNet/IP-to-SCANport module. You
may want to use these to set or obtain information about parameters in
the SCANport product connected to the 1203-EN1. This appendix
contains the following:
List of supported emulated block transfer commands.
Emulated block transfer error response.
Setting up data files for listed emulated block transfer commands.
Examples of each emulated block transfer command listed.
Emulated block transfer is a method used by some SCANport
peripherals to read and write information using PCCC messages. Some
Allen-Bradley EtherNet/IP 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.
What is Emulated Block Transfer
!
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.
