The I/O subsystem also supports Serial interface cards as well as the Ethernet I/O interface.

These various I/O products provide a wide range of interfaces to meet the needs of your control application.

The SD Plus also supports CHARMS and WirelessHART IO cards.

The CHARMS I/O card (CIOC) connects via the redundant Ethernet

ports of the controller and provide a highly distributed and flexible I/O solution called Electronic Marshalling.

Up to 16 CIOC’s can communicate with one controller, each providing up to 96 individually configurable signal types.

The WirelessHART I/O card provides redundant communication for up to 100 WirelessHART devices,

providing high availability and reliability of wireless data.

Up to 16 Wireless HART I/O cards can communicate to a single controller.

Control modules are automatically scheduled by the controller, based on their assigned scan rates.

This allows each control function to be optimized based on the process dynamics.

Modules scan times can be set as fast as 100 ms, and as slow as 60 seconds.

The number of control modules that can be assigned to a controller depends

on the complexity and scan rate of each module, and the available CPU and memory.
