Create a new Modbus Master configuration

To create a new Modbus Master configuration:

  1. Open the IO Drivers ()window.
  2. Insert a configuration ().

  1. Select the MODBUS Master driver:
  2. Insert a Master/Port ( ) corresponding to your MODBUS settings:

  1. Insert a Slave/Datablock () and enter the corresponding information.

Note: It is possible to automatically declare the variables by checking the Declare variables

checkbox. The name of the declared variables must be filled in the Prefix cell.

  1. Variables can be inserted one by one. Use the Insert Variable button () and enter the corresponding information.

When a variable is mapped to a data block in a master configuration you can select it to be:

🞂​        An exchange of data (exchange between the MODBUS map and the T5 variables).

🞂​        A status (diagnostic information provided to the application).

🞂​        A command (using a variable for driving the stack).

  1. Variable information within a data block can also be edited in the grid. From this grid it is also possible to declare variables in the database doing a right-click on a variable.

  1. The import/export in a CSV format is available using the right-click mouse button on an element of the configuration and then choosing to Import/Export Children.

This feature will import/export the sub-level. For example, a right-click on the Datablock (#1) and then Export Children (#2) will export all the block’s variables (#3). An export from the Port will export only the Datablock configuration, etc.
