Table 86
The I²C Bus parameter VPAN can be used to select the start line of the expansion. To
expand the upper part of the incoming signal with the factor 2.0, VPAN should be set to
zero. To expand the lower part, VPAN should be equal to 143. That means in case of
VPAN=0 the first used line is line 1 and in case of VPAN=143 the first used line is line
144.
Dependent on the I²C Bus parameter VERINT a certain number of input lines of the input
field is required. Therefore not all VPAN values are allowed. The formula below can be
used to calculate the maximum allowed VPAN value depending on the chosen VERINT
value.
Floor symbol means: take only integer part of x
