Print Statements
While the DI-159 PLC is connected to the host computer, print statements can be observed on
the Hyper Terminal console window.
Print statements can be used to print integer expressions, using either a decimal or hexadecimal
output radix, or printing raw ASCII bytes:
print [ dec | hex | raw ] expression [;]
Or strings:
print
string
Or various combinations of both:
print string , [ dec | hex | raw ] expression , ... [;]
If the expression specifies an array, its entire array contents are printed. If the expression ref-
erences an input "pin variable", the corresponding DI-159 PLC input pin is sampled to eval-
uate the expression.
A trailing semi-colon (;) suppresses the carriage-return/linefeed that usually follows each
printed line.
Note that when the DI-159 PLC is disconnected from the host computer, print statement output
is simply discarded.
