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
• 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.
Accessing a Secondary Index
1. Press MODE and then press DISPLAY to activate secondary index. The
icon appears under the index field.
2. Enter the secondary index, and then enter the values to set the secondary index.
