The SX controller also supports CHARMs and WirelessHART I/O

cards. The CHARM I/O Card (CIOC) connects via the redundant

Ethernet ports of the controller to provide a highly distributed

and flexible I/O solution called Electronic Marshalling. Up to

16 CIOC’s can communicate to one controller, each providing

up to 96 individually configurable signal types.

The capacity limits of the SX controller may vary depending on

the particular application, amount of CHARM I/O Signals and

as well control performance requirements. Enhanced memory

handling and hardware alerts covering capacity and memory,

via indexes, got added to the diagnostic information of the SX Controller.

It is ideally suited for larger

units with higher I/O counts. It can be field mounted close to

the equipment, or centrally located in an equipment room.

For more traditional installations with central marshalling

cabinets, CHARM I/O cards can be mounted in standard I/O

cabinets providing Electronic Marshalling. CHARM I/O cards

can also be used for highly distributed I/O applications.
