• Parameter names are shown in italics.
The function can be enabled and disabled with the Operation setting.
• 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.
