8.17 Commands for String Processing
String processing enables you to use the PLC program to generate and
manipulate any texts. Use Module 9082 to display these texts in the PLC
window of the screen, and delete them with Module 9080. A string
accumulator as well as 100 string memories (S0 to S99), in each of which you
can save a maximum of 128 characters, are provided in the control for string
processing:
Example
String accumulator and string memory are volatile, which means that they are
erased by the control when power is switched off. The operand "S" is available
for string processing. You can use the operand "S" with different arguments.
