Appendix
B
Supported Block Transfer
Messages
Appendix Objectives
Appendix B provides information about the Block Transfer messages
supported by the Remote I/O communications module. In this
appendix, you will read about the following:
• Block transfer status word.
• Setting up data files for block transfer messages.
• Examples of block transfer messages.
• Block transfer quick reference.
Important:
This appendix provides detailed examples of block transfer
messages. For information about block transfer messages,
also refer to Chapter 5.
Supported Block Transfer
Messages
The following table lists the examples of block transfer messages in
this chapter.
Refer to the quick reference on page B-22 for a complete list of block
transfer messages.
!
ATTENTION: Hazard of equipment damage exists. If
block transfer messages are programmed to frequently
write parameter data, the EEPROM (Non-Volatile Stor-
age) will quickly exceed its life cycle and cause the prod-
uct to malfunction. Do not create a program that fre-
quently uses block transfer messages to write parameter
data to a product. Datalinks do not write to the EEPROM
and should be used for frequently changed parameters.

This function can be accessed in the module and product. The following examples describe
how to access it in the product. To do so in the module, add 16384 to the decimal value of
header word 2.
