3.43 Modbus RTU/TCP View
The Modbus RTU/TCP View is used to assign Modbus addresses to individual parameters.
By selecting Modbus RTU/TCP in the Hierarchy Tree, the Modbus RTU/TCP View will appear on the right (see Figure 117). The right part of
the window displays all of the drive parameters. The number of parameters that appear depends on the User Level.
Figure 117: Modbus View
An external device such as a Human Machine Interface (HMI) or PLC can be used to monitor or edit individual drive parameters. The Epsilon
EP-P drive uses 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.
