V-memory element – used for printing V-memory contents in the integer format or real
format. Use V-memory number or V-memory number with “:” and data type. The data types
are shown in the table below. The Character code must be capital letters.
NOTE: There must be a space entered before and after the V-memory address to separate it from the text
string. Failure to do this will result in an error code 499.
Example:
V2000 Print binary data in V2000 for decimal number
V2000 : B Print BCD data in V2000
V2000 : D Print binary number in V2000 and V2001 for decimal number
V2000 : D B Print BCD data in V2000 and V2001
V2000 : R Print floating point number in V2000/V2001 as real number
V2000 : E Print floating point number in V2000/V2001 as real number with
exponent
Example: The following example prints a message containing text and a variable. The “reactor
temperature” labels the data, which is at V2000. You can use the ‘: B’ qualifier after the V2000
if the data is in BCD format, for example. The final string adds the units of degrees to the line
of text, and the $N adds a carriage return / line feed.
V-memory text element – used for printing text stored in V-memory. Use the % followed
by the number of characters after V-memory number for representing the text. If you assign
“0” as the number of characters, the print function will read the character count from the first
location. Then it will start at the next V-memory location and read that number of ASCII
codes for the text from memory.
Example:
V2000 % 16 16 characters in V2000 to V2007 are printed.
V2000 % 0 The characters in V2001 to Vxxxx (determined by the number in
V2000) will be printed.
# Character code Description
1 none 16-bit binary (decimal number)
2 : B 4-digit BCD
3 : D 32-bit binary (decimal number)
4 : D B 8-digit BCD
5 : R Floating point number (real number)
6 : E Floating point number (real number with exponent)
X1
Print the message to Port 2
when X1 makes an off-to-on
transition.
PRINT K2
“Reactor temperature = ” V2000 “deg. $N”
Message will read:
Reactor temperature = 0156 deg.
