PARAMETER_NAME
Setpoint Rate Down
SP_RATE_DN
18 ALL
Positive, 0 disables
rate limiting PV units
+INF
Data Type: Float
Ramp rate for downward set point changes. When
the ramp rate is set to zero, the set point is used
immediately.
Setpoint Rate Up
SP_RATE_UP
19 ALL
Positive, 0 disables
rate limiting PV units
+INF
Data Type: Float
Ramp rate for upward set point changes. When the
ramp rate is set to zero, the setpoint is used
immediately.
Setpoint High Limit
SP_HI_LIM
20 ALL PV Scale +/‐ 10% 100
Data Type: Float
The highest set point value allowed. SP_HI_LIM
must be greater than SP_LO_LIM.
Setpoint Low Limit
SP_LO_LIM
21 ALL PV Scale +/‐ 10% 0
Data Type: Float
The lowest set point value allowed. SP_LO_LIM
must be less than SP_HI_LIM.

Fault State Time
FSTATE_TIME
23 ALL Positive, seconds 0
Data Type: Float
Time from failure detection to reaction if failure still
exists.
Fault State Value
FSTATE_VAL
24 ALL PV Scale +/‐ 10% 0
Data Type: Float
Preset value to use if I/O_OPTS Fault State to Value
or Use Fault State Value on Restart is set.
