RCAS Timeout
SHED_RCAS
26 RW ALL Positive 640000
Date Type: Unsigned32
Time duration (in 1/32 millisecond) at which to
give up on computer writes to function block
RCAS parameters. If this time is exceeded
then the function block will change to a mode
other than RCAS based on the SHED_OPT
parameter setting. Shed from RCAS mode
never happens when SHED_RCAS is set to
zero.
ROUT Timeout
SHED_ROUT
27 RW ALL Positive 640000
Data Type: Unsigned32
Time duration (in 1/32 millisecond) at which to
give up on computer writes to function block
ROUT parameters. If this time is exceeded
then the function block will change to a mode
other than ROUT based on the SHED_OPT
parameter setting. Shed from ROUT mode
never happens when SHED_ROUT is set to
zero.
Fault State
FAULT_STATE
28 RO N/A
1=Clear
2=Active
1=Clear
Data Type: Unsigned8
Forces output function blocks that are not Out
of Service to the fault state condition. While this
parameter is active the output function blocks
will go to an actual mode of Local Override
(LO) and will perform their fault state actions
(see Action On Fault Detection for the output
blocks on pages 5-70 and 5-149 of this
section). This parameter is used to test the
fault state behavior that normally occurs when
there is a communication problem between
devices. This parameter is changed by the
SET_FSTATE and CLR_FSTATE parameters
so long as the feature Fault State is selected
(see Feature Selection [index number 18] in
this table).
Set Fault State
SET_FSTATE
29 RW ALL
1=Off
2=Set
1=Off
Data Type: Unsigned8
Selecting Set changes the parameter
FAULT_STATE to Active. This is essentially a
“write only” parameter as it will always read
OFF because it is defined as momentary.
Writing a value of OFF has no affect. To use
this parameter the feature Fault State must be
selected (see Feature Selection on page 5-5).
Clear Fault State
CLR_FSTATE
30 RW ALL
1=Off
2= Clear
1=Off
Data Type: Unsigned8
Selecting Clear changes the parameter
FAULT_STATE to Clear and clears the output
function blocks of the FAULT_STATE if the
field condition, if any, has cleared. This is
essentially a “write only” parameter as it will
always read OFF because it is defined as
momentary. Writing a value of OFF has no
affect. To use this parameter the feature Fault
State must be selected (see Feature Selection
on page 5-5).
Max Notify
MAX_NOTIFY
31 RO N/A 3 3
Data Type: Unsigned8
The maximum number of alert reports that this
device can send without getting a confirmation.
To control alert flooding, the number can be set
lower by adjusting the LIM_NOTIFY parameter
value. For DVC6000f Series instruments, this
value is fixed at 3.
Max Alerts Allow
LIM_NOTIFY
32 RW ALL 0 to MAX_NOTIFY MAX_NOTIFY
Data Type: Unsigned8
The number of alert reports that this device
can send without getting a confirmation up to
the maximum permitted in the parameter
MAX_NOTIFY. If set to zero, then no alerts are
reported.
