Figure 5.2. Generic I/O device Configuration Screen
Below, each configuration parameter is described. The proper setting for a drive with a default data
configuration is also listed. Figure 5.3 lists the default drive data configuration.
a. %I Length (Default = 16)
The number of %I's assigned to the drive should be equal to 16 times the number of bit-mapped global
data words broadcast by the drive. Bit mapped parameters should be mapped first in the
GEN250/251and defined using %Is in the PLC configuration.
b. %Q Length (Default = 16)
The number of %Qs assigned to the drive should be 16 times the number of bit-mapped directed control
words (directed data). Bit mapped parameters should be mapped first in the drive and defined using
%Qs in the PLC configuration.
c. %AI Length (Default = 6)
The number of %AIs assigned to the drive should be equal to the number of non-bitmapped global data
words broadcast by the drive.
d. %AQ Length (Default = 1)
The number of %AQs assigned to the drive should be equal to the number of non-bitmapped directed
control words.
