Maintenance Enable
Maintenance Enable (MAINT_ENABLE [63]) enables
or disables conditions that can cause a maintenance
alert. A maintenance alert indicates the device or
some part of the device needs maintenance soon.
Table C-2 lists the available PlantWeb alerts.
Advise Enable
Advise Enable (ADVISE_ENABLE [64]) enables or
disables conditions that can cause an advisory alert.
An advisory alert indicates informative conditions that
do not have a direct impact on the device’s primary
functions. Table C-2 lists the available PlantWeb
alerts.

PlantWeb Alert Reporting
Failed Suppress
Failed Suppress (FAILED_MASK [65]) determines
which of the failed alert conditions are suppressed so
that they are not reported. Even if reporting is
suppressed, the bit in Failed Active (FAILED_ACTIVE
[59]) is still set.
Maintenance Suppress
Maintenance Suppress (MAINT_MASK [66])
determines which of the maintenance alert conditions
are suppressed so that they are not reported. Even if
reporting is suppressed, the bit in Maintenance Active
(MAINT_ACTIVE [60]) is still set.
Advise Suppress
Advise Suppress (ADVISE_MASK [67]) determines
which of the advise alert conditions are suppressed so
that they are not reported. Even if reporting is
suppressed, the bit in Advise Active
(ADVISE_ACTIVE [61]) is still set.

Tag Description
The Tag Description (TAG_DESC [2]) is a 32
character description used to assign a unique
description to each block within the digital valve
controller to describe the intended application for the
block.
Pressure Units
Define the output and supply pressure units
(PRESSURE_UNITS [90]) in either psi, bar, or kPa.
Temperature Units
Enter the temperature units
(TEMPERATURE_UNITS
[89]) in degrees Fahrenheit or Celsius. The
temperature is measured from a sensor mounted on
the digital valve controller’s printed wiring board.
Travel Units
Define the units for valve travel (TVL_UNITS [91]) in
inches, centimeters, millimeters or degrees.
Length Units
Define the units for valve dimensions
(LENGTH_UNITS [92]) in inches, centimeters, or
millimeters.
Area Units
Define the units for actuator area (AREA_UNITS [93])
in inches
2
, centimeter
2
or millimeter
2
.
Spring Rate Units
Define the units for actuator spring rate
(SPRING_RATE_UNITS [94]) in lbs/in
2
or N/M.
Relay Type
Enter the Relay Type (RELAY_TYPE [42.5]).There are
three categories of relays that result in combinations
from which to select.
Relay Type: The relay type is printed on the label
affixed to the relay body:
A = double-acting or single acting
B = single-acting, reverse
C= single-acting, direct
Special App: This is used in single-acting
applications where the “unused” output port is
configured to read the pressure downstream of a
solenoid valve. See page 17 for additional information.
Lo Bleed: The label affixed to the relay body
indicates it is a low bleed version.
