MMaxWOG
(Metasys/Maximo Work Order Generator)

MMaxWOG is a custom software application written for Honeywell, Inc. to automatically create Maximo work orders based on specific Metasys PMI point conditions.

Functional Description

The MMAXWOG program is a standalone Windows application that will run on a Metasys PMI NT4/WIN2K platform that has access via Ethernet to an Oracle Maximo database and an AspenTech Historian database.  The program will allow a user to enter a number of Metasys system/objects and some trigger values for those objects.  The program will periodically connect to the Historian database and the Metasys database, search for the system/objects to be checked and determine if the object is in alarm or has hit a work order trigger level.  If an object has been triggered, the object name along with the Maximo equipment ID assigned to that name is passed to the Maximo table METWOGEN.  The Maximo system will automatically generate a work order when it finds an entry in this table.

The Historian database will be configured to capture point history data and trend data for specific Metasys objects that will be used to generate work orders.  The point history data (analog or binary) will by default be stored in the history database every 30 minutes or when a change of state occurs.  The value and the status are saved.  The analog data can be setup to trend at specific time intervals if point history is not used.

The AspenTech Historian database can reside on a separate NT workstation from PMI.  The database will hold a fixed number of records and will revolve to overwrite the oldest time stamp when the database is filled.

Metasys runtime objects can be analyzed using either Metalink to gather real-time runtime values or by reading the Metasys archive totalization data.

In order to minimize operator input errors, pull-down lists will be utilized.  When adding a new system/object to be tracked, a pull-down list will be generated from the tags that are being utilized in the Historian database and in Metasys.  Therefore, the point history or trend object must be setup correctly in Metasys in order to pick the object from the pull-down list.  Likewise, when the operator assigns a Maximo equipment ID to a system/object, a pull-down list will be available for all valid equipment ID’s.  If an equipment ID doesn’t exist, it will need to be created from the Maximo program.
