•
Each function block symbol shows the available input/output signal.
•
the character ^ in front of an input/output signal name indicates that the signal
name may be customized using the PCM600 software.
•
the character * after an input/output signal name indicates that the signal must
be connected to another function block in the application configuration to
achieve a valid application configuration.
