A nearly unlimited number of CAL data can be generated, managed and included in the actual operation of the
CWS 500N1.x
. If the operator is working with more than two CDN’s or clamps, the internal stores F1 / F1 are
not sufficient and ICD will have to be used which assures the security of data storage.
