There are two classes of FRSI add-on options, FRSIRB_OPTS and FRSIPID_OPTS. The FRSIRB_OPTS options are add-on I/O options for the DeltaV Bias/Gain and Ratio blocks. The FRSIPID_OPTS options are add-on control options for the DeltaV PID block.
Causes cascade input on IN_1 to be interpreted as cascade closed, regardless of substatus on the function block.
Is the reset term based upon the control parameter (BKCAL_OUT) of the downstream block. Prevents windup caused by limiting of the downstream block or from dynamic performance because of tuning. The downstream block must have Use PV for BKCAL_OUT set as an I/O option for Dynamic Reset Limit option to be used in the upstream block.
When False, the gain modifier is 1.0. Otherwise, it is calculated. Refer to the PID function block execution topic for more information on non-linear gain (KNL).
When the status of PV becomes Bad and the mode transitions to Man because of the Bad PV status, the value of OUT is 5 scans previous.
This feature is enabled through the PID block's "Use PIDPlus" option on the FRSIPID_OPTS parameter. PIDPlus should be enabled when the control measurement is provided by a WirelessHART transmitter or a sampled analyzer. The tuning of the PIDPlus should be based on the process gain and dynamics; the sample rate of the measurement has no impact on tuning. When PIDPlus is enabled, it is recommended that the module execution rate is set much faster, for example, 1 second faster than the rate at which the measurement is updated to minimize delay introduced into the control loop. Also, if PIDPlus is enabled, filtering should not be used in the AI and PID block since the PIDPlus feature detects a new measure based on the value changing. If filtering is required, adjust the damping in the transmitter. The "Use PIDPlus" option cannot be enabled in PID blocks assigned to H1 cards or PID blocks converted for use in fieldbus devices.
