Shared IONet
The Shared IONet function (with ControlST
*
V04.06 or higher) enables the sharing of Mark VIeS Safety inputs or Mark Stat
Wind Converter inputs with another basic process Mark VIe controller set, saving the cost of redundant sensors and I/O.
Specific configurations supported include:
•
One Mark VIeS Safety controller set and one Mark VIe controller set
•
Two Mark VIe controller sets
•
One Mark Stat Wind power conversion controller set and one Mark VIe controller set
Note
The Mark VIe UCPA controller platform does not support Shared IONet.

Shared IONet Example
The owner controller allows for the configuration of the owned I/O modules, writes outputs, reads SOEs, and provides
diagnostic information. Owned I/O modules are attached to their owner controller that can configure and write to them, and
obtain their IP addresses from their owner controller. Outputs from controllers are received by their owned I/O modules (not
shared I/O modules).
Note
Refer to
Mark Controllers Shared IONet User Guide
(GEH-6812) for more information.
A shared I/O module sends field device inputs to both its owner controller and to the consumer controller. The consumer
controller receives the field device inputs from the shared I/O modules that are owned by the other owner controller.
Configuration of the control sets is managed with the ToolboxST application. The computer with the ToolboxST application
communicates with the I/O devices through a software gateway function residing in the controllers.
