Installation Scenarios - ABB LevelMaster 7100 User Manual

Using PCCU32
PCCU32 is the primary interface for the family of ABB Totalflow host controller products. It is used to configure the controller to
be able to support communication with the LevelMaster. A special purpose application, the LevelMaster application, is activated
within the controller to request, receive, display, and store measurement data from the sensor.
IMPORTANT NOTE: PCCU32 versions 4.1 and higher support the LevelMaster application.
PCCU is used to accomplish the following:
Activation and configuration of the LevelMaster application in the host controller
Data collection and display for up to eight LevelMasters
Gross volume calculation for up to eight tanks using tank strapping table inputs.
Terminal connection over the local communications port.
Data trending through the Trend System application
RAMS-configurable alarms, alarm by exception and alarm cry-out.
Selectable tank data display and storage units for collected levels, temperature, and volume data. Units may be selected
using PCCU32, WinCCU or MODBUS
Power duty cycling for power conservation through digital outputs using the I/O system application.
Push-to-Read display to allow a view of selected data on the LCD display
Level calibration or bias
IMPORTANT NOTE: Configuration of the flow computer or remote controller to support LevelMaster can also be done
using WinCCU. WinCCU supports a remote configuration utility which provides the same configuration functionality as
PCCU. Collection of the LevelMaster data stored in the flow computer or remote controller is also supported from
WinCCU and other ABB Totalflow software applications.

Installation scenarios

The LevelMaster can be installed in several different field configurations. The choice of configuration depends on the site
requirements, measurement data gathering requirements, and the level of automation and control required.
The scenarios described in this section apply to both the general-purpose (non-hazardous) and hazardous location installations.
Hazardous locations require an additional component in the installation: an intrinsically safe barrier also available for purchase
from ABB.
Installation with host control
The LevelMaster installation with host control consists of a single or multiple LevelMasters (on an RS-485 bus) connected to a
host controller (Figure 2). The host controller can be either an ABB Totalflow host controller or a third-party controller which
supports standard RS-485 communication and ASCII protocol.
When connected to any of the ABB Totalflow host controllers (flow computers or remote controllers), options for automated
measurement data retrieval, level control, and monitoring become available. Totalflow host applications such as PCCU32,
WinCCU32, and TDS32 can be configured to communicate with the LevelMaster (using ASCII protocol) for data-gathering and
reporting.
Power to the LevelMaster can be provided from the host controller or from an external power supply. When powering from the
controller, power can be available from the same RS-485 port used for communication. ABB Totalflow flow computers or remote
controllers, for example, offer power from the COMM ports.
