Command Line Options

Help Contents

Introduction

You can use command line options to change the way the operator interface starts. For example the --Connect option will automatically connect the operator interface to a Fernhill SCADA Server.

These command line options are supported:

OptionDescription
--Connect=ADDRESS Automatically connects the operator interface to a Fernhill SCADA Server. The ADDRESS parameter can be one of the following:
  • A node name, for example: scadasvr
  • A full qualified domain name, for example scadasvr.internal
  • An IP Address, for example: 192.168.1.8
--ConnectLocalService Automatically connects the operator interface to the Fernhill SCADA Server running on the local computer. This is equivalent to:
--Connect localhost.
--StartView=VIEWNAME Overrides the starting page to ViewName.
VIEWNAME is the full tag name of the page to display.
--FullScreen Starts the Operator Interface in full screen mode.
To exit full screen mode, press F11.
--TimeZone=ZONE Overrides the time zone used to display date and time of day values.
For example --TimeZone=America/Los_Angeles overrides the operator interface to display timestamp values in Pacific Standard Time.
--Locale=LOCALE Overrides the locale used to display messages in an alternative language.
For example --Locale=de overrides the operator interface to display messages in the German language.
Note: Translation of the user interface into alternative languages is work in progress.
--DateFormat=DFORMAT Overrides the way date values are displayed.
For example --DateFormat=dd-MMM-yyyy overrides date values to show: date, month name, and year. For example 12-Mar-2019.
See Date and Time of Day Format for the format of the DFORMAT value.
--TimeFormat=TFORMAT Overrides the way time of day values are displayed.
For example --TimeFormat=HH:mm.ss.SXXX overrides time of day values to:
  • Show tenths of seconds instead of thousandths of seconds.
  • Show an ISO 8601 time zone indicator.
See Date and Time of Day Format for the format of the TFORMAT value.
--GraphicMode=MODE Chooses the graphics API used to draw graphics.
MODE can be one of these values:
  • Auto (the default)
  • Direct3D
  • OpenGL
  • GDI
  • Cairo
The default mode is Auto, where the operator interface will choose the most appropriate mode for the hardware. Not all modes are supported on all operating systems.

The GraphicMode Option

Operating systems often provide more than one library for drawing graphics. For example in Windows:

The Operator Interface automatically chooses the best available option for drawing graphics. You can override the automatic selection and tell the Operator Interface which graphics library to use. This table shows which modes are supported on the different types of hardware.

Mode Windows Linux Android
Direct3D Yes No No
OpenGL Yes Yes Yes
GDI Yes No No
Cairo No Yes No
