Using the front panel with non-switch channels
To read a value from the main front panel screen, select the channel and press
TRIG. To see a digital I/O channel in hex format (instead of normal binary) use
TRIG.
A star symbol (*) or exclamation point symbol (!) may appear after the reading.
The meaning of the symbol depends on channel type.
A star symbol (*) appears after the reading to indicate that the reading
matches the MATCH setting for digital I/O and totalizer channels.
An exclamation point symbol (!) appears after the reading to indicate an
overload state condition on that channel for digital I/O and DAC channels.
An exclamation point symbol (!) appears after the reading to indicate an
overflow state condition on a totalizer channel.
If the power state is OFF for totalizer or DAC channels, the display shows
“DISABLED” instead of any readings.
The following table lists the front panel channel attributes that indicate the
various channel mode settings (ICL equivalent
channel.setmode()
), channel
output enable (ICL equivalent
channel.setoutputenable()
), and channel
label (ICL equivalent
channel.setlabel()
). Some of the attributes have
alternate symbols, depending on the operation performing on front panel and
whether it is being used with the 6 or 12 character label symbol.
For digital I/O and totalizer channels, the label symbol is listed first, followed
by a comma and then mode symbols. If the label is the factory default
setting, then only the mode is listed.
For DAC channels, the label symbol is listed first, followed by a comma and
then mode symbols, followed by another comma and the output enable
symbol. If the label is the factory default setting, then only the mode and
output enable symbols are listed.
