• The ^ character in front of an input or output signal name in the function block
symbol given for a function, indicates that the user can set an own signal name in
PCM600.
• The * character after an input or output signal name in the function block symbol
given for a function, indicates that the signal must be connected to another
function block in the application configuration to achieve a valid application
configuration.
• Dimensions are provided both in inches and mm. If it is not specifically mentioned
