Property Description of Numeric Display Element
Fast Refresh
If this option is selected, the element can be displayed immediately when switching
the screen. Please note that this function is designed to provide fast value refresh
speed for the element which performs communication frequently. Therefore, only 4
elements (including display element and input element) can be fast refreshed on one
screen. If the user use this function on too many elements, it may affect the normal
speed of HMI operation. So, we recommend the user not to activate this function if not
necessary. The user can set the Fast Refresh Rate by clicking

command. There are three levels of the Fast Refresh Rate and they are
High, Medium and Low.
Character Display
Table 3.8.3 Property Description of Character Display Element
Property Description of Character Display Element
The user can use this element to read the value of the specific address, convert them to text or character
and display on the screen. The read value must be in ASCII format or the user cannot see the display text or
character. (The max. string length is 28words.)
Read Address
The address can be internal memory or the controller address. (Please refer to Table
3.2.2 Property Description of General Buttons.)
Text Size
Text Color
The user can set the text size and text color provided by HMI to determine the text
display on the element. HMI provides 8~64 kinds of default text font for the user to

(Please refer to Table 3.8.2 Property Description of Numeric Display Element.)
String Length
The range is with 1 ~ 28 words.
Set the read address as Internal Memory 0, i.e. $0, set the string length to 6, and
create three Numeric Entry elements. Then, set the data format of these three
Numeric Entry elements as hexadecimal and enter the value as follows:
$0 = 4241 (Hex)
$1 = 4443 (Hex)
$2 = 4645 (Hex)
Then, the above screen will display.
Please note that character display element reads the Byte value, and the data length
of the internal memory $ address is Word, which is composed of two Bytes.
Therefore, one Word can represent two Bytes. However, as the high byte and low
byte of the value that read by the character display element will be exchanged, when
reading the Internal Memory $0 (=4241 (Hex)), the real display character will become
“AB” and vise versa. Please refer to the following table.
