Notes
•
This function block is a template for designing a unique command line interpreter and requires
customization. See the customization steps below.
•
The command streaming tools provided in the Comm Toolbox are designed to interpret commands
starting with a two character (two byte) command code followed by either delimiter separated parameters
or no parameters. The reason for this is because two ASCII bytes can easily be converted to an INT,
which is used with the CASE statement in this function block. Example commands are located in the
customization steps below.
