Setting Up Parameters

By selecting Modbus in the Hierarchy Tree, the Modbus View will appear on the right (see Figure 87). The right part of the

window displays all of the drive parameters. The number of parameters that appear depends on the User Level.

Figure 87: Modbus View

An external device such as a Human Machine Interface (HMI) or PLC can be used to monitor or edit individual FM-3/4

module parameters. The FM-3/4 module and base drives use a 32-bit Modbus RTU communications protocol.

In order to view or modify a parameter, a Modbus address must be assigned to the specific parameter. To do this, locate the

parameter you wish to read/write to or from in the variables list in the middle of the view. Once you have found the proper

parameter, click and hold the left mouse button over the parameter. While still holding the button on your mouse, drag the

parameter into the Modbus window area on the right of the view. Now let go of the mouse button.

The New Assignment dialog box will appear. This will automatically assign the next available modbus address, or allow you

to enter a different Modbus address. Click OK, then you will be able to read or write the parameter at that address.

Address ranges are as follows:

Any individual Modbus address can be deleted by selecting the parameter you wish to delete, and click on the Remove button.

The address selected will be removed from the list. If you wish to delete all of the Modbus addresses that have been created,

then simply click on the Remove All button. All of the addresses will disappear and the Modbus window will be empty.
