I/O Modules Chapter 8
Reconfigure an I/O Module Via a Message Instruction
To reconfigure an I/O module via a message instruction, use this procedure.
1. Set the required member of the configuration tag of the module to the new
value.
2. Send a Module Reconfigure message to the module.
For more information about using Message instructions, see the Logix5000
Controllers General Instruction Reference Manual, publication
1756-RM003 .
Add to the I/O Configuration
While Online With RSLogix 5000 software, version 15.02.00 or later, and Logix Designer
application, version 21.00.00 or later, you can add I/O and other devices to the
controller configuration while you are online and in Run mode.
The modules and devices you can add while online depends on the version of the
software you are using. Later versions have more modules and devices that can be
added while online.
You can add these modules and devices to the local or remote chassis via the
unscheduled portion of a ControlNet network or via an EtherNet/IP network.
For more information to add to the I/O Configuration while online, see the
Runtime/On-line Addition of ControlLogix (1756) I/O over ControlNet and
EtherNet/IP White Paper, publication
LOGIX-WP006 .
Modules and Devices that Can be Added While Online
These modules and devices can be added to the ControlLogix controller I/O
configuration while online as of RSLogix 5000 software, version 19.01.00 or later
and Logix Designer application, version 21.00.00 or later.
EXAMPLE Reconfigure an I/O module
When reconfigure[5] is on, the MOV instruction sets the high alarm to 60 for the local module in slot 4. The Module
Reconfigure message then sends the new alarm value to the module. The ONS instruction does not allow the rung to send
multiple messages to the module while the reconfigure[5] is on.
