Following the acquisition of DELTA LOGIC Automatisierungstechnik GmbH in April 2025, Softing Industrial Automation GmbH will launch siAccess, the successor to DELTA LOGIC’s proven ACCON AGLink communication library, in December 2025. The transition from ACCON AGLink to siAccess represents a major technological update and strengthens Softing Industrial’s position as a leading provider of industrial communication and OT/IT integration solutions.
Modern communication library for PC–PLC integration
For many years, ACCON AGLink has enabled fast, flexible, and reliable data exchange between PCs and Siemens controllers. The software provides seamless access to various PLC types, communication paths, and operating systems. This creates a solid foundation for automation, visualization, and monitoring applications.
The new siAccess focuses on simplified, secure, and future-proof communication paths and enhanced cross-platform usability. Key highlights include:
By phasing out legacy serial interfaces and focusing on today’s most relevant industrial protocols, siAccess offers developers and integrators a more streamlined environment for automation, monitoring, and analytics applications. The solution is designed to simplify deployment in both desktop and embedded Linux environments and will continue to evolve in alignment with emerging cybersecurity and connectivity standards.
Seamless migration for existing customers
Customers with active maintenance contracts for ACCON AGLink will benefit from a smooth migration path to siAccess, including access to updates, extended platform support, and redistribution options for developers. Migration offers and technical guidance are available directly from Softing Industrial.
