EMERSON VE3008 MQ Controller Module The MQ Controller provides communication and control between the field devices and the other nodes on the control network.

Introduction 

The MQ Controller provides communication and controlbetween the field devices and the other nodes on the controlnetwork. Control strategies and system configurations createdon earlier DeltaV™ systems can be used with this powerfulcontroller. The MQ Controller provides all the features andfunctions of the MD Plus Controller, with the same amountof memory.The control languages executed in the controllers are describedin 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/Ointerface channels located on the subsystem. As soon as anI/O interface is plugged in, the controller knows the generalcharacteristics of the field devices managed by that I/Ointerface. This reduces the no value engineering associatedwith configuration.

Connect to Electronic Marshalling and Wireless I/O.Starting in DeltaV v14.3, CHARMs and wireless devicesconnected through CHARM I/O Cards (CIOC) and WirelessI/O Cards (WIOC) can be assigned to the MQ controller.This makes it easier than ever to add I/O to an existingcontroller by simply adding a CIOC and/or WIOC to theDeltaV Area Control Network.

Easy to useTotal control. The controller manages all control activities forthe I/O interface channels. It also manages all communicationfunctions for the communications network. Time stamping,alarming, and trend objects are also managed within thecontroller. The controller executes all control strategy withexecution speeds up to every 100 ms.

Data protection. All online changes made to controlparameters are automatically stored for later upload into theengineering database. This way, the system always retains acomplete record of all the data that has been changed online.

Advanced operations. The MQ Controller is equippedto handle the DeltaV Batch option, as well as advancedcontrol functions.

Data pass-through. The controller is equipped with the abilityto pass smart HART® information from field devices to anyworkstation node in the control network. This means you cantake advantage of applications, such as Asset ManagementSolutions AMS Device Manager, that enable you to remotelymanage the HART information contained in your HART orFOUNDATION Fieldbus equipped devices.

Prepares you for the future. As your system grows, you canexpand your software license to increase the number ofdevice signal tags (DSTs) allocated to the DeltaV controller.Begin with 50 and expand to 750 DSTs. Control strategycomplexity and control module scan rates determine overallcontroller performance and application size. A redundantcontroller may be added to back up an MQ Controller online.The standby controller comes online automatically, with abumpless transition.

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