Abstract
A system, method, and software product are provided for updating parameters, such as requested packet intervals (RPIs), in a network. The system may include one or more PLCs, communication controllers, and I/O devices coupled in a communication network, such as EtherNet/IP. A request to change a parameter (e.g., scanning rate or timeout value) is transmitted from the PLC to an I/O device specifying a new parameter value or time-out value. The I/O device may receive the message, use a temporary time-out value while processing the message, and transmit an acknowledgement confirming the new value to the PLC. The I/O device may use the updated parameter and new time-out value. The updated parameter may be implemented without the need to take down and re-establish network connections to the affected devices.
