Reconfigure a module via a MSG instruction

To change the configuration of an I/O module programmatically, use

a MSG instruction of type Module Reconfigure to send new

configuration information to an I/O module. During the

reconfiguration:

• Input modules continue to send input data to the controller.

• Output modules continue to controller their output devices.

A Module Reconfigure message requires the following configuration

properties:

To reconfigure an I/O module:

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.

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 prevents the rung from

sending multiple messages to the module while the reconfigure[5] is on.
