Arrays 
Parameter arrays may be accessed either as a whole or as a single 
element.   
 
Using the parameter number (instance number) that represents the whole 
parameter with attribute 5 will return / modify the contents of all elements.   
 
Using the parameter number that represents a single element will allow 
access only to that element. 
 
See Appendix A – Array Parameter Numbers. 
 
Strings 
String parameters may be accessed via its parameter number.  This is in 
the format of a SHORT_STRING.  See Appendix B – Data Types. 
 
String arrays may not be accessed as a whole array, but may be 
accessed via each element. Each element has its own parameter 
number.  See the AC30 Product Manual HA501717U001 for more 
information.
