A Smarter Path to Automation Evolution

Instead of ripping out legacy systems and installing entirely new hardware and cabinet infrastructure, SDe Series products offer a space-fit, pluggable approach which enables stepwise, in-place upgrades that minimize risk and disruption to process operations - 02.

By retaining key infrastructure such as existing cabinets, field wiring, termination units, and cabling, the SDe Series helps owner operators keep production on schedule while evolving systems with minimal downtime. And because components can be swapped within existing physical spaces, sustainability is improved by reducing waste. In addition, the use of newer technology reduces energy consumption while replacing only value - add components lowers overall costs and provides increased functionality

This is innovation with continuity: low disruption, high flexibility, and a smarter way to modernize.

Stepwise Evolution

The ability to upgrade older automation systems across industries is key to future-proofing plant operations and investments. Recognizing the need to innovate through continuity, ABB has purpose-built SDe Series hardware to extend the life of ABB Ability™ Symphony® Harmony and all predecessor systems. With flexible options to evolve, enhance and expand ABB Harmony, Symphony DIN (SD) and INFI 90 systems - which are currently installed in over 7,000 sites globally - the  SDe (and SDev) Series helps owner operators reduce risks and lower ownership costs while modernizing their control installations regardless of the system architecture. These include replacement of individual Harmony rack modules, Evolution Harmony rack module mounting units (MMU) and upgrading DIN-Rail mounting bases.

SDe modules embedded within SDev module assemblies allow incremental, module-by-module replacement and upgrades of Harmony rack modules. Additionally, SDe modules mounted in Evolution Mounting Chassis (EMC) enable stepwise, controller-by-controller replacement of Harmony rack modules - 03. Since the EMC is a space-fit functional replacement for Harmony MMUs, all I/O cables and field wiring remain undisturbed. By preserving both hard assets (system infrastructure, cabling and wiring) and soft assets (the Intellectual Property associated with the customer’s control logic), SDe  Series Control and I/O modules foster innovation with continuity to meet changing needs.

When used for process expansions or greenfield applications, SDe Series Control and I/O modules can be mounted on horizontal or vertical DIN-Rails. Along with mounting flexibility. DIN-Rail mounting bases, provide additional functionality including the ability to force I/O signals (based on IOC FBs), support for I/O module redundancy, HART signals (AD11e, AI12e, AO02e)  local and remote sequence of events timestamping (AD11e, DI06e), and the use of only standard +24 VDC module power.

Offering a scalable compact, modular network-centric architecture, all SDe Series Control and I/O products provide for seamless interconnections with smart field, electrical devices, and advanced applications allowing for network diagnostics, redundancy and heightened connectivity. Specifically, the SDe Series features a flexible, high-performance Fast Ethernet-based plant network (PN800), and intelligent electrical and field device integration via PROFIBUS, HART, IEC 61850, IEC 60870-5-104, EtherNet/IP, DNP 3.0 and Modbus TCP communication protocols.  

The Common Platform for the Future

As the global leader in providing distributed control systems for more than a decade, ABB has over 35 years of experience evolving the Symphony family of systems to support control applications across industries - 04. Dedicated to ensuring that each new generation is seamlessly compatible with previous generations of products, ABB Ability™ Symphony® Plus SDe Series is the common platform for the future. Plant managers can rely on ABB’s e-class control and I/O sub-system to minimize disruption, costs and risk by providing multiple flexible options to incrementally upgrade and expand their older control systems efficiently, securely and optimally. This low-disruption, stepwise evolution approach for automation control system hardware helps plant owners protect their Symphony Harmony and predecessor system investments as they evolve, enhance and expand their automation technology according to their life cycle plans.
