Configuring how to write MODBUS data to a MySQL database is very much similar to configuring how to write data to MSSQL. Only main differences are described in this manual.

1. Download and install the 32-bit version of MySQL ODBC Connector (the ODBC driver) for MySQL from

Driver section
Fig. 1 Driver section

2. The structure of a table in the database will look like this:

CREATE TABLE `modbus_data_2` (
  `TIMESTAMP` datetime NOT NULL,
  `ITEM1` int(11) DEFAULT NULL,
  `ITEM2` double DEFAULT NULL,

If you specify any other data type than String for ITEM1 or ITEM2 in the MODBUS settings, you should create the columns of the corresponding types while creating a table.

3. Create an ODBC data source for your MySQL database.

4 Follow steps #1-9 from the previos tutorial for MS SQL: "Writing MODBUS values to MS SQL".

5. During "Binding", you should take into account that the names of the table and its columns are case-sensitive in MySQL.
