Marcom OPC Client to Database records values from an OPC DA or UA Client to various types of Databases. Bi-directional function on the first row to write and read from database to OPC DA or UA Client

**Marcom OPC Client to Database** is, on one side, an OPC Client DA/AE/UA and on the other, it can interface with different databases.

Once the OPC Client, database connections, and related tables are configured, it is possible to configure the mapping of OPC variables to database table fields. It can also manage multiple OPC connections and multiple database connections simultaneously.
The connection modes between OPC Client and Database are:
 - **Timed writing** of a table record with current OPC variable values 
 - **Writing based on a trigger variable** of a table record with current OPC variable values
 - **Bi-directional update** of the variables that make up a table by updating and reading only the first row of the table

It can connect, locally or remotely, to the following databases:
 - Microsoft SQL Server
 - MySQL Server
