2.10 Measuring Values
Read out Measured Values
In menu [Operation / Measured Values], both measured and calculated values can be
viewed. The set of available measured values depends on the WIC1 variant.
Display Options
The user can dene how measured values are to be displayed within the DiggiMEC HMI and
Smart view:
• Current values are displayed relative to the nominal current In, or:•
• Current values are displayed as primary values in A.•
Of course, rimary values can be displayed only if the connected CT type has been
correctly congured. Besides, there are further, variant-specic aspects, because the
related parameters cannot be reached via DIP/HEX switches.
Settings via Software
WIC1‑1, WIC1‑4, or WIC1‑2, WIC1‑3 with the setting »Prot . Settings valid« = “Software”:
The display options, CT type and nominal current (»In,relative« or »CT pri«) are set via
ordinary setting parameters within the menu branch [Field Para / CT].
• The CT type is selected at »CT Type«. As soon as one of the available CT types•
W(E)2, … , W6 is selected, the display can be toggled at any time between relative
and primary current values.
•
»Display of Meas. Values« = “Based on In,relative” — Display of relative current
•
values.
The nominal current is set at »In,relative« as a relative value in units of [In
,min
].
• »Display of Meas. Values« = “Primary current values” — Display of primary current•
values.
The nominal current is set at »CT pri« as a primary current in [A].
These settings can be saved by Smart view in a parameter le, just like any setting
parameters. (Parameter les have lenames of the form *.WiPara.) This makes it easy to
load a set of settings into several WIC1 devices.
Settings via DIP/HEX Switches
WIC1‑2, WIC1‑3 with the setting »Prot . Settings valid« = “Switches”:
The display options and CT type are set via Direct Commands within the menu branch [Field
Para / CT]. A Direct Command is always immediately transferred to the WIC1 and executed.
The result is – comparable to the settings via software described above – that the display
of current values changes. However, Direct Commands are never saved within a *.WiPara
le. Therefore it is necessary to execute them separately on each WIC1, as is the case for
the DIP/HEX switches.
The nominal current »CT . In,relative« is set – as a relative value in units of [In
,min
] – via the
DIP/HEX switches, see also ╚═▷ “11.1.3 Setting of the Rated CT current In”. (By the way, this
is an ordinary setting parameter, that would be saved within a *.WiPara le.)
