Product Description

The SX controller primary function is to execute control

modules that are designed to meet the specific control

requirements of the plant. These control modules use process

signals from the controller’s I/O subsystem and provide

communication of process data to the rest of the DeltaV

control system for operator interaction and data collection.

Each controller node can be installed as a simplex or redundant

node. The controllers are connected to the I/O carriers,

which are mounted to the right of the controller carriers.

Up to 8 carriers with 8 cards each can be connected to the

local bus I/O, for a total of 64 traditional I/O cards. In addition

to the 8 local I/O carriers, each controller can communicate

with an additional 16 Remote I/O units hosting traditional

card based I/O.

In addition to traditional I/O cards, the local bus supports

fieldbus technologies, including Foundation fieldbus, Profibus DP,

DeviceNet and AS-i protocols. 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 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 www.abb-drive.com 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.
