Flip: Used to flip bit lamp and needs to be configured during design time. Available options
include None, Horizontal, Vertical and Both.
Rotation: Used to rotate a bit lamp in predefined angles and needs to be configured at design
Circle: By default, a bit lamp object shape is in Rectangle. Select this if you wish to change the
bit lamp shape to a circle. It is more useful to show status of digital inputs for the
operator during Run time.
How to show status of an individual bit in Analog type tag
Sometimes, you will get a 16 bit/32 bit tag from a PLC with different diagnostic information, and
you would like to show 16 bit/32 bit lamps in the Recorder screen.
When a Bit lamp is linked with an Analog tag, for example: Int16/Int32, it has two bands. By
default, Band1 value is 0 and Band 2 value is 1. In this case, using each bit lamp, it is possible to show the
status of each individual bit status within 32 bits as per configuration available at band editor.
In the above figure, Tag2 is an analog type (4 byte), so, a TagBitNo combo box will appear for the selection
of the required bit within 32 bits (0 to 31).
If Tag2 is Digital type tag, then, TagBitNo. Combo box is not visible.
6.3.9.1.17 Word lamp
Word lamps are similar to Bit lamps but linked with an Analog type tag only. It can have many
bands. By using the band editor, it is possible to display a different foreground color, different background
color, different text, different symbols, different Blink color, and control visibility when Tag values change
values during Run Time.
For example: Tank Level indicator
When Tag1 value is
0 to 10, Text = Low Low Level, Color = Yellow Blinking
11 to 20, Text = Low Level, Color = Yellow Background
21 to 80, Text = Normal, Color = Green back ground
81 to 90, Text = High level, Color = Red back ground
91 to 100, Text = High High Level, Color = Red blinking
Create 5 bands as shown
time. Available options include 0
, 90
, 180
