2.
Data type MyMachineStruct (VAR_IN_OUT ‘MachineData’) is only an example structure. A custom
structure must be designed to uniquely match the needs of the application. An example is shown below.
3.
Change the ‘MachineData’ DataType in the CommandProcessor function block to match your structure

Initialize the configuration elements in CircularByteBuffer.
a.
a. CmdDelimiters are used to mark the end of a complete command. Up to four characters can
be specified. Typically, <cr>, which is BYTE#13 or <cr><lf>, which is BYTE#13 BYTE#10 are

Return or Carriage Return & Line Feed.
b.
b. PrmDelimiter specifies the character that separates individual parameters within a command.
If PrmDelimiter is not specified, the function will automatically default to a comma, (BYTE#44).
c.
