CHAPTER 11 ALARMS AND ALARM DISPLAYS
11.3.4. Embedding Variable in the Appended Text of Alarm Message
1. The appended text can have one embedded variable.
2. Use the following format to specify an embedded variable:
@@ read_address<display_format>
For example, the following embedded variable in the appended text will display the
32-bit floating point number
stored in W300 with the format of 4 total digits and 1 fractional digit.
(Current temperature: @@W300 °C)
If the value of W300 is 123.456 when the alarm occurs, the following text will be appended to its alarm message:
(Current temperature: 123.4 °C)
3. The
read_address can be any valid word address.
4. The
display_format has the following format:
Dt.f
The D is a one-letter or two-letter code to specify the data type.
The t is a number to specify the total number of digits to be displayed.
The f is a number to specify the total number of fractional digits to be displayed.
The following table shows the rule of specifying the display_format.
Data Type D (Data Type) t (Total Digits) f (Fractional Digits)
16-bit Unsigned Integer U 1~5 t >= f >= 0
16-bit Signed Integer S 1~5 t >= f >= 0
16-bit BCD Integer D 1~4 t >= f >= 0
32-bit Unsigned Integer UD 1~10 t >= f >= 0
32-bit Signed Integer SD 1~10 t >= f >= 0
32-bit BCD Integer DD 1~8 t >= f >= 0
32-bit Floating Point Number F 1~10 t >= f >= 0
5. Note that the embedded variable specified in the appended text of the first language will be used in the appended text
of all other languages no matter what embedded variables are specified in those appended text.
