Personalising the graphic display
7.2.5 Some examples of the use of a device images
By associating a null image you can only see the display, which can be placed on the page; this way you can obtain an
easy synopsis of the plant.
To associate a null image, go to Main menu>Configure>Devices>Image, choose the General sub-page and
write “none” in the General/Name field.
If you associate an image of the machine into which the electronic control connected to the display is inserted, it can be
easier and more intuitive to represent the logistical structure of the plant. To choose the image file use the procedure
described for Screenshot 7.3.
Note: before configuring the device image, deselect the Change automatically checkbox in Main
menu>Configure>Devices>Image>General.
7.3 Grouping devices in ‘Machines’
7.3.1 Machines and Devices in RICS terminology
Normally RICS software manages all connected devices as separate entities.
Each related image can be freely placed on the main display to as to allow the creation of synoptic tables.
However sometimes a real machine may be controlled by more than one electronic device (or the related data may be
sampled by more than one data-collection module). In this case it is helpful to group the device images which are
otherwise treated as independent. The concept that represents this situation is known as the “Machine” in RICS.
Therefore in RICS a “Machine”, is a group of one or more electronic devices.
Often the following procedure is followed to represent a machine comprising more than one device:
• The image of the main device (probably quite large) is associated to that which represents the machine
• The other device images are set as “null”.
In this case, when dragging the image you also drag all the other displays associated to machine component devices.
7.3.2 Machine identification
In RICS each machine is identified by a number grater than 0.
Normally the first machine is index number 1, the second 2, etc…
For all devices in a machine go to Main menu>Configure>Devices>General (see Screenshot 7.6): in the
Grouping field, set the Machine ID field with the number of the machine to which the device must be
associated.
Screenshot 7.6: Machine ID and Machine leader items.
7.3.3 Main device
One of the devices must be labelled as the main machine device, by selecting the Machine leader checkbox (next
to the Machine ID box, see Screenshot 7.6). In this case if the device that is the “main device” is moved from
the main display, the other devices that comprise the machine are moved at the same time.
