Primary And Secondary Indexes; Primary Index; Secondary Index - Siemens MAG 1100 Operating Instructions Manual

Primary and Secondary Indexes

Primary Index: relates to direct input or output and can refer to relays, communications
ports, and other parameters. In parameters that allow secondary indexes, the primary
index is often referred to as a point.
Secondary Index: relates to previously indexed parameters where the parameter
requires a second index, permitting multiple values on an indexed input or output.

Primary Index

Example Setting: P111[3] = 52
1
• P111 sets the Relay Control Function
• P111(3) = 52 sets Relay #3 to a value of 52.

Secondary Index

Parameters with a secondary index permit multiple values for a primary index (point). For
example, a volume calculation based on vessel characterization breakpoints requires a
distinct set of breakpoints for each measured point.
Thus the primary index refers to the measurement point, and each secondary index refers
to a characterization breakpoint value.
