Setting up networks safely.

The CAN in Automation (CiA) association has released the second version of the CiA 319 specification. This specifies how to implement and to configure functional-safe devices compliant to EN 50325-5 (CANopen Safety). CANopen Safety services and protocols are used especially in mobile machines and industrial machine control. 

The European standard does not specify the configuration of functional-safe devices; this is given in detail in CiA 319.

“This document fills the gap und helps CANopen Safety system designers to safely set-up networks,” explained Holger Zeltwanger, CiA Managing Director. “Additionally, this document addresses editors of CANopen device profiles using SRDO (safety-related data objects as specified in EN 50325-5.” 

SRDOs comprise two CAN frames with bitwise-inverted CAN data fields and different CAN identifiers. CANopen Safety is approved up to SIL 3 (safety integrity level).

Functional safety for mobile machines.

The Anybus Safe2Link Remote IO-CS, from HMS Networks, is a rugged, type-approved I/O device designed to simplify the integration of functional safety into AGVs, AMRs, and other mobile machines. With TÜV-certified safety functions and support for CIP Safety over EtherNet/IP, the Anybus Safe2Link Remote IO-CS provides the fastest, most reliable path to compliance with ISO 3691-4 and the upcoming EU Machinery Regulation 2023/1230.

The unit mounts directly on the machine, enabling system integrators and machine builders to add a safe remote stop and manage local or remote safety signals without custom hardware design.

Since the Anybus Safe2Link Remote IO-CS connects with existing local safety logic, system integrators can implement the same safety functions across AGV/AMR platforms from different suppliers. This significantly simplifies integration and reduces the effort required for the recertification of functions such as safe remote stop.

Advanced safety features such as SafeBound™ (fast local and slow remote safe reaction) and SS1-t (controlled safe stop) allow machines to react predictably, protecting both people and equipment.

With certification up to SIL 3 (IEC 61508) and PLe/Cat. 4 (ISO 13849-1), the Safe2Link Remote IO-CS is type-approved and ready to deploy. Its rugged IP54 enclosure, dual M12 Ethernet connectors, and straightforward D-Sub I/O interface make it well-suited for harsh industrial environments.

The launch of the Anybus Safe2Link Remote IO-CS expands HMS Networks’ functional safety portfolio, which also includes embedded hardware options and TÜV-certified safety protocol software. This flexible approach allows OEMs and system integrators to choose the right level of integration for their applications — from plug-and-play devices to fully customized safety hardware.

“Functional safety is no longer optional — it’s essential for accessing global markets and building trust with customers,” says Stefan Kraus, Functional Safety Product Manager at HMS Networks. “The Anybus Safe2Link Remote IO-CS gives system integrators or machine builders a plug-and-play solution to meet the latest requirements with minimal integration effort. This means faster time-to-market and safer, smarter machines.”

User-friendly programming for mobile machines.

openSYDE, from the control systems company STW, is a framework and toolset for the implementation, analysis, maintenance and documentation of functions and programs in control systems for mobile machinery. It is characterized above all by its open architecture. It offers the OEM open interfaces to other programs and the possibility to integrate third party components.

It supports machine manufacturers with various tasks around the control system throughout the machine lifecycle, through design, production, and service. openSYDE also supports application programming. Integrated logi.CAD 3 realizes this in a particularly user-friendly way.

The focus of openSYDE is the control system architecture and design, with peripherals. For this purpose, it has the programming environment logi.CAD 3 integrated into the workflow. logi.CAD 3 can be started directly from openSYDE and with openSYDE generated code, automatically takes over the base configuration of the control system for the further programming. This is one part of the development environment’s lifecycle support, which accompanies the machine manufacturer throughout the entire product lifecycle.

With logi.CAD 3, together with the runtime system Micro-Runtime-System µRTS 3, powerful and cost-effective solutions can be realized. logi.CAD 3 offers a powerful ST (Structured Text) Editor and the graphical FBD (Function Block Diagram) Editor. The environment and control system architecture also allows the integration of C and C++ code, and the complete data storage is in ASCII format. In contrast to proprietary binary codes from other suppliers, this makes further processing far simpler - especially in conjunction with the integrated code generator.

logi.CAD 3 utilizes the open source programming environment Eclipse. This means a large number of additional plugins are available, many of them free of charge. One example is support for the source code management system GIT. Using Eclipse as a basis ensures long-term availability and development of both the environment and plugins.

Another advantage of logi.CAD 3, and thus of openSYDE, is the runtime system µRTS 3 of the programming environment mentioned above. µRTS 3 requires around 30 kB of memory. Thus, the machine manufacturer has almost the entire memory of the target controller available for the application. Further, the CAN safety protocol ECeS developed by STW, which is inherently supported by the STW controllers of the ESX family, is also particularly resource friendly. The SIL2/PL d-certified protocol significantly reduces the amount of data on the CAN bus and provides a higher speed of data transfer than the CANopen safety protocol.

openSYDE, logi.CAD 3 and the ESX controller family complement each other in an optimal way. Together they provide manufacturers of construction, agricultural, forestry and municipal machinery, as well as automated guided vehicles and mobile working robots, with a perfect ecosystem for system design, analysis, monitoring and service of their machines.
