Product Details

DASA110 3ASC25H705/7 Product Description

The ABB DASA110 3ASC25H705/7 is a high-integrity industrial network interface module engineered for the Advant Controller series, delivering seamless data link connectivity across Profibus-DP and MasterBus/300 communication architectures. In modern smart factory environments where real-time data flow between field devices, PLCs, SCADA platforms, and enterprise systems is non-negotiable, the DASA110 serves as a critical protocol bridge — translating, routing, and stabilizing industrial data across every layer of the automation hierarchy.

From signal acquisition at the sensor level through to data visualization on SCADA dashboards, the DASA110 3ASC25H705/7 ensures that every node in the network — whether a remote I/O rack, a variable frequency drive, an HMI terminal, or an edge gateway — communicates with precision and without latency gaps. Its role in the Advant system architecture is foundational: it enables the AC450 and AC460 controller families to participate in distributed Profibus-DP networks, extending their reach to field instruments, motor control centers, and intelligent field devices that demand deterministic cycle times and fault-tolerant communication.

In a fully connected smart factory, the DASA110 3ASC25H705/7 operates at the intersection of field-level sensing and supervisory control. Consider a typical deployment: field sensors and actuators — pressure transmitters, flow meters, and proximity switches — feed raw process signals into remote I/O modules such as the ABB S800 I/O series. These I/O nodes communicate upstream via Profibus-DP, where the DASA110 acts as the network master, polling each slave device on a deterministic cycle and aggregating process data into the Advant controller's memory map.

The Advant AC450 controller, equipped with the DASA110 interface, then forwards processed data via MasterBus/300 to higher-level systems — including ABB Advant Station 500 Series operator workstations and SCADA servers running ABB Industrial IT or third-party platforms such as Wonderware InTouch or Ignition SCADA. HMI terminals on the plant floor receive real-time tag updates, alarm states, and trend data, enabling operators to monitor motor drives, valve positions, and energy consumption without communication delays.

Variable frequency drives — such as ABB ACS800 or ACS580 series — integrated into the Profibus-DP segment report speed references, torque feedback, and fault codes directly through the DASA110's network interface, eliminating the need for point-to-point analog wiring and reducing commissioning time significantly. Similarly, intelligent motor control centers and soft starters connected as Profibus slaves deliver diagnostic data — current draw, thermal status, and trip history — into the SCADA historian for long-term trend analysis and predictive maintenance scheduling.

At the edge, industrial Ethernet switches and protocol converters bridge the Profibus segment to higher-bandwidth OPC-UA or Modbus-TCP networks, allowing the DASA110-linked Advant system to interface with modern edge computing gateways and cloud-connected data platforms. This architecture supports the full data lifecycle: from raw signal acquisition, through protocol conversion and network transmission, to real-time monitoring, alarm management, remote diagnostics, and enterprise-level data visualization — all anchored by the DASA110's stable, field-proven communication backbone.

Many industrial sites operating legacy Advant infrastructure face a common set of challenges: protocol fragmentation between older MasterBus/300 segments and newer Profibus-DP field devices, data silos that prevent SCADA systems from accessing real-time field data, and limited remote diagnostic capability that forces on-site intervention for routine fault analysis.

The DASA110 3ASC25H705/7 directly addresses these pain points. Its dual-protocol architecture bridges MasterBus/300 and Profibus-DP within a single module, eliminating the need for external protocol converters and reducing network complexity. By centralizing field device communication through a single, well-defined interface, it breaks down data silos — every Profibus slave, from remote I/O to variable speed drives, becomes visible to the SCADA historian and HMI layer simultaneously.

Remote diagnostics are enabled through the Advant controller's built-in diagnostic registers, which the DASA110 populates with network health data: bus cycle times, slave response errors, communication timeouts, and node dropout events. Maintenance engineers can monitor these parameters from the SCADA workstation or a remote engineering station without physical access to the control cabinet, reducing mean time to repair and supporting proactive maintenance strategies.

For production line transparency, the DASA110 enables tag-level data visibility across every connected device — supporting alarm tracking, event logging, and production KPI dashboards that give plant managers real-time insight into throughput, downtime events, and energy consumption. As production requirements grow, additional Profibus-DP slaves can be added to the network without hardware changes to the controller, providing a scalable expansion path that protects the existing automation investment.

Q1: What communication protocols does the ABB DASA110 3ASC25H705/7 support? The DASA110 3ASC25H705/7 supports Profibus-DP (as network master or slave) and MasterBus/300, enabling it to serve as a protocol gateway between ABB Advant controllers and a wide range of Profibus-compatible field devices including remote I/O, drives, and intelligent instruments.

Q2: Is the DASA110 compatible with modern SCADA and HMI systems? Yes. When installed in an Advant AC450 or AC460 controller, the DASA110 enables data exchange with SCADA platforms via the controller's OPC server or serial communication interfaces. It is compatible with ABB Industrial IT, Wonderware, Ignition, and other OPC-DA/UA-capable supervisory systems through appropriate gateway configuration.

Q3: How does the DASA110 support remote diagnostics and network stability monitoring? The module populates diagnostic registers within the Advant controller with real-time Profibus network health data — including bus cycle times, slave error counts, and communication timeout events. These registers are accessible from remote engineering workstations and SCADA clients, enabling fault detection and network performance monitoring without on-site presence.

Q4: What warranty and pre-shipment testing does the DASA110 3ASC25H705/7 carry? Every DASA110 3ASC25H705/7 unit is covered by a 12-Month Warranty and undergoes functional testing prior to shipment to verify communication integrity, backplane interface operation, and protocol response. Stock is sourced from verified inventory channels to ensure authenticity and operational readiness upon delivery.
