Interface

The interface setting is fundamental for operation as an electrical measurement input.
Setting: CoE Index 0x80nD:11 "Input Interface"

Different measuring ranges are available depending on the channel:

Bridge voltage_UBridge (for n=0 (Ch. 1), n=4 (Ch. 2))

• None
• ±20 mV
• ±75 mV
• ±4 V

Reference voltage_USense (for n=1 (Ch. 1), n=5 (Ch. 2))

• None
• ±5 V
• ±10 V
• ±12 V

If the interface is set to "None", the corresponding channel is disabled.

Note: When the interface is changed, the following CoE parameters of UserScale, Range Error, Limit 1/2 are reset to the default setting.

The intermediate value after this functional unit can be viewed in index 0x90n0:03 "Value after interface".
