Note
The representation of limits matches the analog value representation. Observe range limits
when setting the limit values.
Module operating modes
The table below lists the operating mode codes to be entered at byte 0 of data record 128
(see the previous figure.)

Module operating mode Code
8 channels 2#00000000
4 channels 2#00000001
Noise suppression
The table below lists the frequency codes to be entered at byte 1 of data record 128 (see the
previous figure.) 4-channel mode only works if 50 Hz, 60 Hz and 400 Hz noise suppression
is set.
