Project ODBC Plugins

Movicon manages ODBC connection creations using the plugins contained in a Movicon installation subfolder called "ODBCMgr".

When in the process of creating a new project using the wizard ("DataBase Settings (ODBC)"), you will be asked to choose which database format to use for default. The options are:

 

 

Once the project has been created with wizard, the chosen default plugin (using the " DataBase Settings (ODBC)" window) will be indicated in the project's  "Plugin ODBC Default" property and can be changed afterwards if need be. The  "Settings ODBC" command in the project's General properties allow you to modify the connection parameters, in the same way as the wizard's "Customize ODBC Settings" command.  these parameters are saved in the "pluginname.settings" configuration file (i.e. SQLExpress2005.settings) in the ODBCMgr. folder. The configuration xml file structure type will be:

 

<?xml version="1.0" encoding="UTF-16"?>

<parameters>

<ID text="Driver">SQL Server</ID>

<ID text="SERVER">PCTEST\SQL2000</ID>

<ID text="DATABASE">prjSql2000</ID>

<ID text="Trusted_Connection">yes</ID>

<ID text="Description"></ID>

</parameters>

 

"The first time the project is launched into runtime, the ODBC DSN connection will not exist immediately and the settings file, saved in the project's "DATA" folder to enable the parameters to become specific to that project, will be used by Movicon to create it.  Once created the configuration parameters in the default ODBC plugin will be ignored.

MSAccess is used as a default value for those projects created with the Template or Empty Project wizard or those projects pre-existing without being defined with the  "Plugin ODBC di Default" property.

 

Check certain  limitations regarding: the maximum size of individual Databases, the maximum size of tables (ie. the maximum number of Columns for each individual Table), maintenance needed, RAM occupation etc. in the specific documentation of the DBMS used.
