ibaMS8xAI-110VAC Manual
Issue 1.4.1 27
Signal Description
StatusOut Status information about the plugged module (for input
module without function):
0 = Module not initialized
1 = Module running
>1 = Mistake (e.g. module cannot be initialized)
Outputs
DigitalFilterMode Activates the digital anti-aliasing filter in addition to the
analog anti-aliasing filter (if activated)
AntiAliasingFrequency Setting of the cutoff frequency of the digital anti-aliasing
filter
EnableFilter_Ch[00…07] Enables the analog antialiasing filters (per channel)
PwrFrqMode_Ch[00…07] Setting of the measuring interval for grid frequency meas-
urement (per channel)
Additional input signals for buffered access
AI_110VAC_Ch[00…07]_buf Input buffer of analog input signals
AI_Frequency_Ch[00…07]_buf Input buffer of calculated grid frequencies
BufferFillCount Counter, when buffer is filled
BufferOverrun Counter for Buffer-overrun
Additional output signals for buffered access
BufferSize Buffersize
SubSampling Subsampling of the signals
9.2.2 Additional functions
Activating analog filters
If you want to use anti-aliasing filters, these are set up as configuration output and con-
figured as Off-task connector (OTC) or function block.
First, drag the output signals defined in the I/O configurator to the margin of the program-
ming surface, in this example “X2_EnableFilter_Ch00” for the analog input 0.

Create a new Off-task connector in the programming window, assign a meaningful name
to the connector, e.g. “low pass filter” and choose “Input” and Data type “BOOL” under
the Connector type option.
