3.1 Overview
In order to start a connection to a device, you must insert the appropriate communication
module in the project. After the installation, a USS module is configured. With the action
"Parameterize" the user can modified the parameters of the module.
Presently the following communication modules are supported:
USS over serial interface
3.2 USS
3.2.1 General settings
Name
In the edit field, the user can assign a name for the communication module.
Port
In the communication window, you can choose the COM-Ports of the computer where the
inverter is connected to.
Telegram error
The user defines the max number of allowed telegram errors.Telegram errors occur if the
content of a telegram is not correct. That means the answer does not fit to the parameter order.
Normally, each parameter order is answered after 2 telegrams. The number of allowable
telegram errors is the number of tries before the error message appears.
Bus error
The user defines the max number of acceptable bus errors. The bus error appears in the case
when the receiving telegram or the sending telegram was wrong. Incorrect telegrams are
ignored. Here you can program the max number of incorrect bus telegrams before the error
message is generated. In an installation with many interferring signals, the setting of acceptable
errors should be programmed to a higher number.
Simulation of Hardware
With this feature, the user activates or deactivates the simulation of the connected hardware.
