Description

A maxDNA distributed control system. • Remote Processing Units (RPU) consisting of Distributed Processing Units (DPUs) and I/O Modules, which provide control and data acquisition capabilities. • maxSTATIONs providing the human interface with the system • maxNET, a redundant Ethernet network, which interconnects maxSTATIONs and DPUs A maxSTATION may be set up as an: • Operator‟s Workstation • Engineer‟s Workstation • Dedicated Function The Operator‟s Workstation uses maxVUE graphical interface software to provide a graphical view of the process. The software uses both standard and custom displays The Engineer‟s Workstation is used for creating and maintaining configurations and process control documentation using the maxDPUTools configuration management software. It is also used to create and maintain custom graphic displays using the maxVUE graphics editor software. maxSTATIONs may be dedicated to a primary application or function. For instance, maxSTATIONs may be set up to collect and manage process and system alarms, process and event history, archive history, or log history reports, using various maxDNA applications. In network domains, maxSTATIONs may also be configured as proxy servers. To better manage maxSTATION processing loads and to reduce network traffic, Individual maxSTATIONs could be configured for the following specific functions: The SBP software suite includes the following core applications: . such as maxVUE and maxDPUTools. are clients accessing providers for data. historical.

(many located in Custom\SBP) • Database files generated by various applications (located in Custom\Database) • maxDPUTools point configuration databases (located in Custom\Configs) • maxVUE Custom displays (located in Custom\Displays) • maxVUE OCX controls (located in Custom\Controls) .ini) files associated with applications with your own custom settings. Consider the Custom directory to be a safe place to store and preserve custom settings. custom displays. the folders organized under Custom to store maxDNA applications containing custom settings and files. folders under Custom typically contain: • Initialization (. point configurations. Any work stored in Custom is preserved In addition to programs. When Metso Automation releases new software and upgrades. and databases. Settings in the user setting part of the registry database are organized by software application: • maxVUE • maxDPUTools • Software backplane. Specifying Registry Settings The Metso Automation MCS Registry is a database containing the default settings for maxDNA operating system and application-related software. you may customize the settings contained in these two areas The machine settings area of the Registry contains default settings for several maxDNA applications. Changes made in machine settings for software installed on a specific maxSTATION remain in place and are applied globally regardless of user and associated user logon name. user settings and machine settings. Using the MCS Registry Editor tool. .• Utility programs and associated initialization files (located in Custom\SBP) • History Reports (located in Custom\History) Registry and Initialization (ini) Settings Configuring Initialization Files Initialization files are typically text files containing settable options to change the way a software program behaves or to activate optional features. Changes made in the user settings area are associated with a specific user and user logon name. a subset of the Windows registry. The Registry. Such files are read by the maxSTATION startup program when it is first initialized. is divided into two sections. • DPUList. Point Browser Uses it to create the tree selection of the listed DPUs. MaxPROXY Uses it to determine if a data request is directly from a DPU and allows an extra proxy hop. DPU Atom List (diagnostic utility) List of DPUs available from which you can get a summary of atoms by time class. MaxDPUTools Uses it to look up the IP address for a given DPU name and determine if the name references a stand-alone or backup pair of DPUs. This file is referenced by a number of maxDNA applications that need to identify available DPUs in a system. I/O Inventory List of DPUs available to check list and current state of their I/O.

To further balance processing loads. such as alarm and event monitoring. each domain may have alarm masters. For instance. event stations. many of the overhead functions would normally be performed within the domain. and so forth. time synchronization. etc. Assignments are normally set up on maxSTATIONs configured as Operator Stations. Up to 31 independent domains may be configured. event collection and logging. For critical control room applications. A domain typically contains a group of DPUs and workstations that are engineered. alarm management. For example. database configuration. and operated independently from equipment in other domains While items such as live data and historical trends can be retrieved from other domains. event collectors. such as alarm masters. it is recommended that you select specific maxSTATIONs for various control room assignments.Setting up maxSTATIONs with Individual Assignments To balance processing loads. maxSTORIAN stations. and so forth. maintained. not across domains. select two stations for each application in the event one or the other station should fail.

The file is stored in C:\Custom\Database\Wks. you will use a utility called Domain Configurator. Run the Domain Configurator to define the domains and the workstations assigned to the domains.ini file.b. executes the configuration you create to carry out automation functions. you create one configuration database file for each DPU. Use maxDPUTools to assign I/O modules to the Distributed Processing Units (DPUs). performing conversions and logic. All plant data signals and control signals pass through these units. providing control and data acquisition functions. and associated signals. Hardware resources consist of Distributed Processing Unit.ini. . along with control and data acquisition processing A configuration database is composed of function blocks. Distributed Processing Unit The maxDPU. The DPU IP address of the secondary station is one number greater than the address of the primary station. The DPU may be configured as a standalone module or as part of a backup pair. Use maxDPUTools to: Create one or more configurations. These modules provide the physical connection point for the input/output wiring of signals to and from a process. the process controller. When you create a configuration. Click the Enable/Disable Backup button on the configuration download dialog to enable and disable DPU backup Defining I/O Modules The DPU processes analog and digital input/output signals via the family of parallel input/output modules. The backup serial link cable (Part number 081387) carries data signals between the primary and secondary DPUs. Blocks have inputs and outputs which can be softwired together via references to provide a flow of sequential processing from reading input hardware.maxDPUTools Using maxDPUTools. two DPUs are connected to form a backup pair. and define function blocks within the configuration representing an individual DPU’s associated I/O hardware. Blocks can be grouped into larger objects to encapsulate increased functionality into an organizational hierarchy. Install the configuration(s) and load them into their respective DPUs. I/O Modules. Buffers are used to define the I/O inventory and specify signal conditioning and linearizations. Backing Up the DPU In a redundant configuration. If one end of this cable is removed from either DPU. that unit is rendered inactive. A specialized subset of function blocks exists to interface with the I/O and these are known as buffers. a DPU is automatically defined at the root of a configuration hierarchy. Hardware Resources define hardware resources using buffer functions. One DPU is designated as the primary unit and the other DPU the secondary unit. (DPU). DPU IP addresses are listed in a text file called DPUlist. and outputting the results to hardware. as well as a status signal which determines which DPU is active. limit. The I/O Bus Configuration Tool. may then output processed data from other function blocks to an output module connected to a field device I/O Addressing Up to 255 I/O addresses may be assigned to each DPU. the mix of analog versus digital I/O. Other function blocks may then be configured to point to analog and digital input buffers to obtain conditioned signals as input data. These limitations include the number of hardware modules that can be connected to one DPU. requirements of other features within the DPU. I/O Module Types and Associated Signals Function block Categories Table 1-1. I/O addresses are used to access I/O modules or channels of I/O modules.exe. I/O modules provide varying levels of signal conditioning. Function blocks Table . depending on the type and mix of I/O. Use digital and analog buffers to configure digital and high level analog signals coming from I/O modules.I/O modules plug into a Remote Processing Unit (RPU) cabinet card rack along with DPUs and other equipment. Use maxDPUTools to define the desired input or output modules using buffers. Output buffers. in turn. Use thermocouple and RTD buffers to specify linearizations. each corresponding to a signal. the mix of inputs versus outputs. Each digital I/O module supports 16 bits with one address. I/O Analog and Digital Modules and associated signals are defined and configured as buffers and become part of a DPU I/O inventory list. I/O modules communicate with DPUs via an I/O bus. IOBusConfig. the number of I/O addresses available for transfer of I/O values. and alarming (with validity. is used to determine the allowed mix of I/O modules on a DPU‟s I/O bus. Use Atag and Dtag function blocks to assign tagnames to each signal. and the update rate of the I/O. Refer to the next section for information about the I/O Inventory I/O Configuration Rules The amount of I/O that can be connected to a DPU can be limited by a number of different factors. Older legacy modules and analog output modules use one address per channel. data conversion. Each module has from 1 to 16 channels. and error checking) before passing information onto the high-speed parallel I/O bus for further processing by a DPU.
