ABB 2VAA009362R11 VRBX01K04A Compact Bus Ext Kit Vertical

Features and benefits

Termination for up to eight (8) analog I/O process signals within a horizontal row.

All SD I/O modules & bases of all types (Singular or Redundant) AND (Compact or Full-size), are

100% fully compatible with each other. Thus, Singular & Redundant, Compact or Full-size I/O

modules can be mounted within a single, common HN800 I/O bus.

Optional mechanical keying can be implemented to prevent insertion of the wrong I/O module type.

Latching device on the base locks the base into position on DIN-Rail.

Industry standard 35-mm DIN rail, Horizontal row mounting.

Changes to Configuration in 800xA for Symphony Plus  Harmony 

The following configuration related changes have been made to 800xA for  Symphony Plus Harmony in the 6.0 release:

• The SQL Server based ConfigServer Database that contained 800xA for 

Harmony Configuration data has been eliminated in the 6.0 release. The tag 

configuration data is now stored in the Aspect Directory.

• The Harmony Synchronizer Aspect, Tag Importer Exporter, and Import Export 

Configuration utility have been eliminated. A new Harmony Uploader Aspect 

has been added to allow Harmony tag configuration data to be imported to and 

exported from the Aspect Directory.

• A new TagConfig Aspect that supports Aspect Directory based tag 

configuration has been added. The new TagConfig Aspect also provides 

support for 800xA Engineering Environments and Versioning.

• The System Definition object type located under the Harmony OPC Server 

Network object has been eliminated. It has been replaced with a new INFI 90 

System Definition object in the Library Structure and a new ServerConfig 

aspect on the Harmony OPC Server Network object.

• Remote Motor Control Block (RMCB) Text configuration has been removed 

from the Harmony Server TagConfig Aspect. RMCB Text configuration is now 

provided by a new NLS Text Set on the new INFI 90 System Definition object 

in the Library Structure. 

• The Harmony Bulk Configuration Manager has been eliminated. The 800xA 

Bulk Data Manager can now be used to make bulk changes to 800xA for 

Symphony Plus Harmony TagConfig Aspects.

• The 800xA for Harmony Backup/Restore utility has been eliminated. 800xA 

for Symphony Plus Harmony tag configuration data can now be backed up and 

restored through the standard 800xA Aspect Directory backup/restore.

• The Harmony Server Monitor object and TagMonitor Aspects are no longer 

needed and have been eliminated.

processor load

• Optical communication

• Industrial grade hardware with no moving parts

• Long life cycle, easy upgrading

• Robust reliance file system, insusceptible post power loss

07EA90-SI ABB modules are used to convert analog signals to digital signals and transmit them to the control system for monitoring and controlling industrial processes.

These accuracy settings are only used when negotiating for time mastership with 

other nodes in the underlying Harmony control network.

Master Update Period

Master update period is the frequency that Harmony Server synchronizes time with 

the underlying Harmony control network. This property is used only when Time 

Synchronization is enabled. The permissible values are 120 to 3540 seconds.

Message Wait Period

Message wait period is the Period that Harmony Server waits before attempting to 

assume time mastership on the control network. This property is used only when 

Time Synchronization is enabled. The permissible values are between 180 and 3660 

seconds. Additionally, the configured value must greater than the Master Update Period.

Sending Global Alarm Acknowledgement Messages to the Loop

Enable Tag Acknowledgment Broadcast 

To broadcast an alarm acknowledgement for a specific Harmony tag: 

– Select the Tag Acknowledgment Broadcast Enable check box on the  Harmony Tab of the tag. Selecting the 

checkbox enables the connectivity server to broadcast the alarm  acknowledgement for this tag on the communication highway.  

Enable Acknowledgment Transmission 

Configure the module status tag for each node to which the connectivity server  transmits the alarm acknowledgment messages. 

For each module status tag, on the  Module tab, select the Enable Alarm Acknowledgment 

Transmission check box to  have the connectivity server transmit any recently acknowledged alarms.

Broadcasts  will only be sent to a node when the corresponding module status tag is configured  and has alarm acknowledgment transmission enabled.  

Receiving Global Alarm Acknowledgement from the Loop 

Configure the Harmony Server tag to enable receiving global alarm  acknowledgment messages from other nodes on the loop. 

On the Harmony tab, select the Global Alarm Acknowledgement check box to  

enable the connectivity server to process the Global Alarm Acknowledgement  messages received through the INFI-NET loop. 

The connectivity server applies the alarm acknowledgement to the harmony tag that  has the same Harmony address as the broadcast tag.
