Reconfigure An I/O Module Via A Message Instruction; Add To The I/O Configuration While Online - Allen-Bradley 1756-L61 User Manual

Chapter 8 I/O Modules
Reconfigure an I/O module
EXAMPLE
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 prevents the rung from sending multiple messages to the module while the reconfigure[5] is on.

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.
With RSLogix 5000 software, versions 15 or later, you can add I/O and other
devices to the I/O Configuration for the controller while you are online and in
Run mode.
The specific modules and devices you can add while online depends on the
version of RSLogix 5000 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 about adding 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.
