Configuring RSLogix 5000 Software to Access Data on the 1757-ABRIO Module Chapter 5
Unscheduled I/O
Connections in
ControlLogix
There are several tasks you need to complete before you can access
data from ControlLogix. You need to create the following:
Tags for messages
Tags for storage areas
Message commands to read RIO network data
Message commands to write RIO network data
Use RSLogix 5000 message instructions (MSG) to access tags on the
1757-ABRIO module. Refer to RSLogix 5000 Online Help and the
Logix5000 Controllers General Instructions Reference Manual,
publicatio
, for details on messages.
Before you create the MSG instruction, create a tag of type MESSAGE
to act as a control for the MSG instruction. You must also create a
source (write) or destination (read) tag for the data written to or read
from the 1757-ABRIO module.
1. Create Tags For All Messages and All Storage Areas

you will reference
in your message
commands.
