ABB 3BHT300006R1 DO610 digital output 32ch 24VDC

Comprehensive self-diagnostics

Comprehensive self-diagnostics continuously monitor the modules and report any errors through LEDs on

the module fronts and through alarm messages and indications to process operator stations.

Malfunctioning inputs can be disabled and simulated by manual entry while failing outputs are deactivated

or driven to a predetermined safe state automatically.

All I/O modules can be replaced while the system is in service. 

Some modules can even be arranged, trans parently into dually redundant configurations forenhanced availability.

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.

On-board processing capabilities

The process I/O modules are “intelligent” in the sense that module-related signal and data processing is

performed on board as opposed to centrally, by the CPU of the host controller. Time tagging of events,

filtering and gain control are some examples of board-level tasks. 

This functional distribution improves real-time performance and reliability of the 

system as a whole and maintains processing capacity when the system is expanded.

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.

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.

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.
