Reconfigure an I/O Module via a MSG Instruction
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 control their output devices.
To reconfigure an I/O module, perform 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..
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.
