In this article you can check how to set the internal resistance of single pins in E3.series. The attribute can be set in the device properties and its value is expressed in ohms.
See the full video article and optimize your processes!
Previously in electrical checks (E3.eCheck), a global default value can be set for the internal resistance of connecting elements (e.g. connectors and connections) in the settings (under Settings - Electrical Checks - Internal resistance of connect elements [Ohm] :).

How to Define Internal Resistance
To set the internal resistance directly on a pin there are a few ways:
- mark the desired device on the desktop and select the command "Format" - "Device Properties...";
- right-click on the symbol that has been assigned to a component and select the menu command in "Device Properties...";
- right-click a single pin or a symbol's pin text and select "Pin Properties...";
- right-click the desired device in the device tree of the project window and select "Device Properties...", then select the "Pin" tab, right-click the first available cell in the attribute selection list and select the attribute "Internal resistance on pin [Ohm]";
Now enter the internal resistance on the pin in the "Entry" column.

Rules for Definition
- If a connector with more than one pin is placed as a complete connector and no wires are connected to the pins, the default value is used for the calculation.
- If no internal resistance value is defined on both plugged pins, the default value is used for the calculation.
- The internal resistance can only be set on the pins/pin terminals of the connector, ie the default value is used for calculation with symbol-oriented work.
- If the wires are connected to a complete connector, a unique current path assignment is guaranteed. In this case, the resistances on the pins are used for the calculation. Note: Only values from the first pin are used for display. If you want to view the voltages and currents of all pins, this must be done using Pin Properties.
- If a connector pin terminal is assigned to the connector pin, the internal resistance of the connector pin terminal is used. If no internal resistance is defined at the connector pin terminal, the connector pin value is used. Note: Rules 2-4 are valid here.
