Attention:
During the test, the value of the current loop does not follow the current
process.
2.1.1
NORMAL OP
The value of the current loop follows the current process.
2.1.2
4.0 mA
The value of the current loop no longer follows the current process.
It is set to the selected current value.

Attention:
During the test, the binary status does not correspond to the current
process.
2.2.1
NORMAL OP
The binary status of the switching output corresponds to the current
process.
2.2.2
OPEN
The binary status of the switching output no longer corresponds to the
current process. The selected status is tested.

ACTIVE HI
ACTIVE LO
ON
OFF
The current binary status of the binary input B3 is displayed. External
switching of the voltage applied to input B3 activates a change of the
displayed binary status.

Note:
Note:
A reaction to the switching of the voltage applied to input B3 only occurs
when the function of B3 is activated (see Fct. 3.6).
