Description
Specifies the analog input limits to be supervised. See
parameter 112.03 AI supervision
Description
1 = Minimum limit supervision of AI1 active.
1 = Maximum limit supervision of AI1 active.
1 = Minimum limit supervision of AI2 active.
1 = Maximum limit supervision of AI2 active.
Activation of analog input supervision.
Value of analog input AI1 in mA or V (depending on
whether the input is set to current or voltage by jumper
J1).
Value of analog input AI1.
Value of analog input AI1 after scaling. See parameters
112.19 AI1 scaled at AI1 min

Scaled value of analog input AI1.
Selects the unit for readings and settings related to
analog input 1.

Note: The signal is also filtered due to the signal
interface hardware (approximately 0.25 ms time
constant). This cannot be changed by any parameter.
