Rockwell Automation 1203-EN1 EtherNet/IP-to-SCANport Module - Manual (Page 145)

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.
