Chan Enable
. Set to 0 (default) to enable, 1 to disable.
HART Enable
. Set to 0 (default) to enable, 1 to disable.
Range
. Set to 0 (default) for 4 to 20 mA, 1 for 0 to 20 mA.
Alarm Latch
. Set to 0 (default) to disable, 1 to enable. When Alarm Latch is
enabled, status bits hold their state until the user unlatches them via the Unlatch
Bits. See Output Instance (102) for more detail.
Fault Action.
During a fault condition, you may choose the behavior of the
outputs:
•
Low Clamp uses the Low Clamp Value (see below). If clamping has
been disabled, this setting is not allowed.
•
High Clamp uses the High Clamp Value (see below). If clamping has
been disabled, this setting is not allowed.
•
Hold Last State will lock the outputs to the last known value while
ignoring further changes to output words.
•
Fault Value uses the value set by the user (see below).
Program Action
. While the system is idle or in program mode, the user may
choose the behavior of the outputs:
