11 Communication between inverter and PC
Communication between PC and inverter is established with a serial connection.
A cable (cat. no. 41488) is connected to a serial interface on the PC and to termi-
nal X3 of the inverter as shown in the adjacent figure.

11.1 Settings
The serial transmission is parameterized in the inverter entry under Communica-
tion/Settings. The dialog which appears indicates the communication status.
Communication is parameterized below this. The settings include the interface
used on the PC, the transmission speed and the bus address. 0 is preset as the
bus address. It does not have to be changed unless you want to establish a serial
daisy chain connection with several inverters.
The checkboxes under the communication status are used to select whether the
settings saved in the project are to be used for communication or the global set-
tings of POSITool. It can be useful to use the project settings when an inverter net-
work is configured on a PC on which each inverter has a permanently assigned
interface. The disadvantage of the project settings becomes obvious, however,
when the project is transferred to other users.Sometimes online operation cannot
be established with the project settings because another COM interface is being
