Cyclic I/O Messaging
The Powermonitor II supports Cyclic I/O Messaging, which reports
data on a user-configured time increment basis.
Cyclic data messaging is more efficient for applications with slowly
changing I/O (analog); network traffic is reduced and performance is
repeatable.
Typical DeviceNet Network Powermonitor II Using a PLC or SLC Scanner
The Powermonitor II can communicate directly to a PLC or SLC
DeviceNet Scanner module using I/O Messaging and/or Explicit
