CAS_IN (Process)
A remote setpoint value. If used, will be linked to an output of an upstream
block. In some blocks, may be left unlinked, and a local setpoint value
(typically SP) will be used instead.
CAS_IN_D (Process)
A remote setpoint value. If used, will be linked to an output of an upstream
block. In some blocks, may be left unlinked, and a local setpoint value
(typically
SP_D ) will be used instead.
CHANNEL (I/O, Process)
Used by I/O function blocks to select a physical I/O channel. This mapping
is defined by the manufacturer. In the FP-3000, this parameter is
automatically updated when the
FIELDPOINT_MODULE and
FIELDPOINT_CHANNEL parameters are modified.
CLR_FSTATE (Faultstate, Option)
Writing Clear to this parameter causes the device-wide faultstate to be
cleared and output blocks to resume normal execution. Also refer to the
SET_FSTATE and FAULT_STATE parameters.
CONFIRM_TIME (Alarming)
The lower bound on the time the device waits to send alert report messages
if no confirmation is received from a host.
CONTROL_OPTS (Option, Scaling)
A list of options used to adjust the way control blocks, such as the PID
block, operate.
Table 4-11. Control Options
Options Description
Bypass Enable If set, lets you set the BYPASS parameter and bypass the
algorithm’s control.
SP-PV Track in Man Causes the setpoint to track the process variable in Man .
SP-PV Track in ROut Causes the setpoint to track the process variable in ROut .
SP-PV Track in LO or IMan Causes the setpoint to track the process variable in LO or IMan .
