7.1.1 Settings
The serial transmission is parameterized in the inverter entry under
Communication/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
settings of POSITool. It can be useful to use the project settings when an inverter
network 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 used. In this case, you can use the global settings of POSITool.
The global parameterization takes place in the menu Extras/Options in the dialog
screen General (see ).
