Description
Easy to use Total control. 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. Data protection.
All online changes made to control parameters are automatically stored for later upload into the engineering database. This way, the system always retains a complete record of all the data that has been changed online. Cold restart. This feature provides automatic restart of the controller in case of a power failure. The restart is completely autonomous because the entire control strategy is stored in NVM RAM of the controller for this purpose. Simply set the restart state of the controller to current conditions. Has the flexibility to meet your needs Advanced operations. The MQ Controller is equipped to handle the DeltaV Batch option, as well as advanced control functions. You can also use advanced control function such as Neural and Model Predictive Control on the MQ controller. Data pass-through.
The controller is equipped with the ability to pass smart HART® information from field devices to any workstation node in the control network. This means you can take advantage of applications, such as Asset Management Solutions AMS Device Manager, that enable you to remotely manage the HART information contained in your HART or FOUNDATION Fieldbus equipped devices. 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.
Designed to support legacy migration Advanced operations. The MQ controller provides the DeltaV platform to migrate PROVOX and RS3 controllers, and also supports the PROVOX and RS3 Migration I/O interfaces. The existing PROVOX I/O remains in place using the migration I/O interface to PROVOX with support of up to 750 real I/O signals. Serial datasets are migrated to DeltaV serial cards and all virtual I/O are no longer required due to the direct module references possible in the DeltaV system. RS3 system migrations to the DeltaV system are fully supported with MQ Controllers and the migration I/O interface for RS3.
Prerequisites For each controller you will need to select the mounting carrier. Please refer to M-series I/O Subsystem Carriers product data sheets for details. Each controller requires a dedicated system power supply. Please refer to the M-series System Power Supply product data sheet for details. The MQ controller requires v12.3 or later DeltaV software. The MQ controller can be used on a v11.3.1 System by applying a HotFix to the DeltaV system. The MQ controller can be used on a v10.3.1 System by applying a HotFix to the DeltaV system. Assigning CHARMs and Wireless devices to the MQ controller requires DeltaV v14.3 and later software, but is not supported on M-series Controller Interfaces to PROVOX and RS3. Electronic Marshalling requires use of DeltaV Smart Switches between controllers and CIOCs, please refer to Network Considerations for M-series with Electronic Marshalling White Paper.
