Index Selector Examples; Sensor And Measurement - Siemens HydroRanger 200 HMI Operating Instructions Manual

Notes
• Setting up the HydroRanger 200 HMI may be done through the index selector
parameters; however, using the Quick Start Wizards is still the preferred
method to commission the device.
• An indexed transducer is commonly referred to as a Point (short for Level
Point). A Point number refers to indexed transducers.
• Indexes are set in each sub-menu by one or more selector parameters.
• Transducers are always indexed when the dual-point option is enabled.
• On a single-point HydroRanger 200 HMI, transducer parameters are indexed
only if Operation (
Difference) or Average (mode = Dual-Point Average).
• Index selector parameters contain a value for each selector regardless if that
selector is used or not.
• To view or change a parameter that applies to a different index in the same
sub-menu , the new index must be first set in the selector parameter.
• For optimum performance, set selector values accurately for indexed
parameters. Ensure that the correct index value is being changed for each
parameter value.
• If the device is a single point unit, some selector parameters will not be visible
unless Differential or Average operation is selected.

Index selector examples

The examples provided below show the behavior of the index selector parameters for an
application requiring Level measurement and relays to control a small level in small
vessels with pumps and high alarm. See
