Details
The controller and I/O modules communicate over the IONet, a 100 MB Ethernet network that is available in non-redundant, dual redundant, and triple redundant configurations. Ethernet Global Data (EGD) and other protocols are used for communication. EGD is based on the UDP/IP standard (RFC 768). EGD packets are broadcast at up to the system frame rate from the controller to the I/O modules, which respond with input data. IEEE 1588 Precision Time Protocol is used on the IONet to time-align the I/O pack data.
I/O modules from two different applications can share their data on the same IONET with two different sets of controllers. As an example, sensor data that is being monitored by a Safety Controller can be shared with a Balance of Plant controller to simplify the design and reduce the cost of instrumentation. Controller outputs are restricted to the I/O modules designated for their specific application and not shared.
