7.1.3 Setting the DIP switches
You can configure the input signals using the DIP switches on the front (0 mA ... 20 mA or
4 mA ... 20 mA). Any changes to the DIP switch settings will be applied immediately. In
PLC / Modbus/RTU mode, the setting of the input signals is evaluated for error diagnostics.
When set to 4 mA ... 20 mA, for example, it is possible to detect an open circuit.
