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.
