The block input, typically a safety shutdown signal from an
upstream function block, where 0 = trip.

The number of seconds allowed for PV_D to confirm in the 0
state following a transition of OUT_D to Off (0).

This timer starts when OUT_D transitions from On (1) to Off
(0). Its value can range from 0.0 seconds to CFM_TRIP_TIME seconds. When PV_D
confirms that OUT_D is Off, the timer stops. This value is retained until a
subsequent transition of OUT_D to Off.
If the timer times out, the DO_ALERTS alert
Failed to confirm after trip command is set. The alert
clears when OUT_D transitions to On.

DO_ALERTS
(Option bitstring)
|
None
|
NVM:

|
Contains the runtime value of alarm conditions set by the
block (inactive = 0, active = 1)
-
Failed to confirm after trip command
-
Confirm lost while commanded On
For a description of the alerts and information on how to
access them, refer to DO_ALERTS.

FSTATE_TIME
(Floating point)

300
(Seconds)
|
Access:
Configurable, Tuning
NVM:
Restored on Restart
|
The number of consecutive seconds of Bad status allowed on
CAS_IN_D before the fault state becomes active and the block forces OUT_D to
the off-state value of 0. Setting FSTATE_TIME to 0.0 causes the fault state to
occur immediately when status is Bad.
|
|
FSTATE_TIMER
(Floating point)
|
0
(Seconds)
|
Access:

NVM:

|
This timer starts when a new fault state condition is detected
on CAS_IN_D. When the fault state condition clears, FSTATE_TIMER retains its
value until the next time a fault state condition is detected on CAS_IN_D.
|
|
FSTATE_TIMER_H
(Floating point)
|
0
(Hours)
|
NVM:

|
The value of FSTATE_TIMER in hours.

IO_OUT

Configurable options for block reporting features.
-
Alarm conditions do not roll up to module level.

REQUIRE_RESET
(Boolean)
|
False

If REQUIRE_RESET is True RESET must be True for OUT_D_STATE to
transition from the Off-Ready to Reset state to the On state. The block changes
RESET back to False.
