Interface

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

EL3008‑0003

Setting

Measuring range

0: None

-

4: V ±3 V

±3 V

EL3008‑0005

Setting

Measuring range

0: None

-

5: V ±5 V

±5 V

Notice When the interface is changed, the following CoE parameters of User Scale, Range Error, Limit 1/2 are reset to the default setting.

With setting "None" (here in the example on Ch. 2)

Interface 1:

the channel returns "0".

The channel must now be connected as described in chapter "Connecting the analog input".

The intermediate value after this functional unit can be viewed in index 0x90n0:04 "Value after interface".
