ASCII Conversion Instructions
(STOD, STOR, DTOS, RTOS, UPPER, LOWER)
Topic
String To DINT (STOD)
String To REAL (STOR)
DINT to String (DTOS)
REAL to String (RTOS)
Upper Case (UPPER)
Lower Case (LOWER)
Use the ASCII conversion instructions to alter the format of data.
For example
Convert a value from a weight scale or
other ASCII device to an integer so you
can use it in your logic
Convert a value from a weight scale or
other ASCII device to a REAL value so you
can use it in your logic
Convert a variable to an ASCII string so
you can send it to a MessageView
terminal
Convert a variable to an ASCII string so
you can send it to a MessageView
terminal
Convert an entry made by an operator to
