• 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 signal name indicates that the signal must
be connected to another function block in the application configuration
to achieve a valid application configuration.
• Logic diagrams describe the signal logic inside the function block and are
bordered by dashed lines.
• Signals in frames with a shaded area on their right hand side represent
setting parameter signals that are only settable via the PST, ECT or
LHMI.
• If an internal signal path cannot be drawn with a continuous line, the
suffix -int is added to the signal name to indicate where the signal starts
and continues.
• Signal paths that extend beyond the logic diagram and continue in
another diagram have the suffix "-cont."
