Must be true in order for FORCE_OPTS to force the block. |
|
FORCE_TIMEOUT (Floating point) |
1 |
Access: Configurable |
Maximum period the block can be forced to Normal by FORCE_OPTS, in hours. |
|
FORCE_TIMER (Floating point) |
0 |
NVM: Preserved on Download |
Countdown timer indicating how long before the force to normal will be removed if the value of FORCE_OPTS is not Timeout on force to normal for indication only. |
|
IN_D |
False |
Access: Tuning NVM: Restored on Restart |
Monitored value. IN_Dn is extensible from one to four. |
|
INPUT_OPT (Named Set) |
Any |
Access: Configurable |
Determines whether any or all inputs must be tripped to cause the block to trip. |
|

NVM: Preserved on Download |
Indicates the current state of the input. The possible values
are:
|
|
LATENT_TRIP (Boolean) |
False |
NVM: Preserved on Download |
When True, indicates that removing the force will result in a trip. |
|
LOGIC_TYPE (Named Set) |
Negative |
Access: Configurable |
Indicates whether the tripped state is TRUE (Positive) or FALSE (Negative). |
|
OUT_D (Boolean with status) |
False |
NVM: Preserved on Download |
Output value the block. False if Tripped and True if Normal when the logic type is Negative. True if Tripped and False if Normal when the logic type is Positive. |
|

clears. The possible values are:
|
|
RST_LATCH_TIME (Floating point) |
30 |
Access: Configurable, Tuning NVM: Restored on Restart |
