EMERSON A6220 9199-00009 Machinery Health Monitor The controller manages all control activities for the I/O interface channels. It also manages all communication functions for the communications network. Time stamping, alarming, and trend objects are also managed within the controller. The controller executes all control strategy with execution speeds up to every 100 ms.

EMERSON KJ2003X1-BB1 MD Plus Controller Module The control languages executed in the controllers are described in the Configuration Software Suite product data sheet.

Introduction 

The MQ Controller provides communication and control between the field devices and the other nodes on the control network. Control strategies and system configurations created on earlier DeltaV™ systems can be used with this powerful controller. The MQ Controller provides all the features and functions of the MD Plus Controller, with the same amount of memory. The control languages executed in the controllers are described in the Configuration Software Suite product data sheet.

advantage：

Increases productivityThe MQ Controller is as quick as the MD Plus Controller andprovides the same configurable memory as the MD Pluscontroller. The Ethernet ports are full duplex, 100MB/secondmaximum throughput. The results are lower CPU utilizationand higher capacity for control strategies.

Self-addressing. The DeltaV controller is unique in its abilityto automatically identify itself to the DeltaV control network.When the controller is powered up, it is automatically assigned a unique address—no dip switches, no configuring—just plug

and play!

Self-locating. A controller’s physical location is easy to find. LEDs on the face of the controller can be made to flash, providing a strong visual clue.

Automatic I/O detection. The controller can identify all I/O interface channels located on the subsystem. As soon as an I/O interface is plugged in, the controller knows the general characteristics of the field devices managed by that I/O interface. This reduces the no value engineering associated with configuration.

Prepares you for the future. As your system grows, you can expand your software license to increase the number of device signal tags (DSTs) allocated to the DeltaV controller. Begin with 50 and expand to 750 DSTs. Control strategy complexity and control module scan rates determine overall controller performance and application size. A redundant controller may be added to back up an MQ Controller online. The standby controller comes online automatically, with a bumpless transition. For more information, refer to the I/O Redundancy product data sheet.

Mounting. This plug-and-play system structure provides modular system growth with a single controller and can be mounted in a Class 1, Div 2 or ATEX Zone 2 environment. Refer to the System Power Supplies and I/O Subsystem Carriers product data sheets for additional information.
