Description:
These parameters configure the signal type (if current or voltage) that will be read in each analog input, as well
as its variation range. In options 2 and 3 of the parameters, the reference is inverse, that is, the maximum
frequency is obtained with the minimum reference.
In the CFW100-IOAR and CFW100-IOA accessories, the DIP Switch S1:1 set to ON configures the input AI1 for
signal in current. For further details, refer to the Installation, Configuration and Operation Guide of the CFW100-
IOAR and CFW100-IOA I/O Expansion Modules.
