23. Fail-safe Dir.
Sets how analog output and pulse
output will behave if the device is in
a critical state.
The fail-safe direction for pulse
output is valid for ver. 2.0 and later.
Options for fail-safe analog output
direction are:
-- Upscale: Output will be at the
upper limit.
-- Downscale: Output will be at the
lower limit.
-- None: No special output. Output
will be uncertain and display
possibly inaccurate.
Options for fail-safe pulse output
direction are:
-- Low: Do not output a pulse.
-- Hold: Keep the pulse output at
the value obtaining just before
the critical condition occurred.
