RCAS_IN_D (Mode Shedding, Process)
The discrete cascade input for a control or output block set by a remote
host. This is propagated to the setpoint of the block when it is in
RCas
mode. If the block is in RCas mode and this parameter is not updated in
SHED_RCAS time (a parameter in the resource block), the block enters
mode shedding. Mode shedding allows the block to degrade from RCas
mode into some higher priority mode.
RCAS_OUT (Process)
The back calculation output used by the supervisory host when establishing
a Remote cascade loop.
RCAS_OUT_D (Process)
The discrete back calculation output used by the supervisory host when
establishing a Remote cascade loop.
READBACK (Scaling, Tuning)
The valve or actuator position read back from the transducer, in transducer
units.
READBACK_D (Scaling, Tuning)
The transducer state for the actual discrete valve or actuator position.
RESET (Tuning)
The time constant for the integral component of the PID block. It is
measured in seconds per repeat (so larger values have less effect, and
INF
effectively disables the integral term).
RESTART (Diagnostic, Option)
Allows the user to restart the device remotely.
Table B-10. Restart Values
Value Behavior
Restart Resource Restarts the device.
Restart to Defaults Restarts the device, restoring all parameter values to default values.
Restart Processor Restarts the device as if the power was cycled.
