DVC6200f Digital Valve Controller
Detailed Setup - Transducer Block
February 2017

Output Block Selection

Output Block Selection (OUTBLOCK_SEL [112]) defines which output function block (AO or DO) will control the
setpoint of the valve. The output block that is not selected will shed its mode to reflect that it does not have control of
the valve.

Alerts

The DVC6200f provides two levels of alerts; Instrument alerts and Field Diagnostic alerts or PlantWeb alerts. PlantWeb
alerts will be presented to hosts that do not support Field Diagnostic alerts.

Instrument Alert Conditions

Instrument Alert Conditions, when enabled, detect many operational and performance issues that may be of interest.
To view these alerts, open the appropriate status screen on a host such as DeltaV or ValveLink software.

Field Diagnostic Alerts

Some instrument alert conditions can also be used to trigger Field Diagnostic alerts. Field Diagnostic alerts will be
reported in Failed, Function Check, Out of Specification, or Maintenance Required categories, as configured by the
user. When a Field Diagnostic alert occurs, the DVC6200f sends an event notification and waits a specified period of
time for an acknowledgment to be received. This occurs even if the condition that caused the alert no longer exists. If
the acknowledgment is not received within the pre‐specified time‐out period, the event notification is retransmitted.
This reduces the possibility of alert messages being lost.
Field Diagnostic alerts will be mapped to PlantWeb alerts (PWA) as shown below for older DeltaV systems that do not
support Field Diagnostics.
