Three Quick Questions

The buzz on S+ Engineering

1. In terms of security, what can S+ Engineering do?

Security is a serious threat to all systems, especially systems without access control. Previous versions of Composer allowed anyone, no matter the level of authority, to log on to the machine, open up the engineering editor, and edit or entirely delete whatever they choose. Security was non-existent in this case, which was an undeniable issue. Thankfully, access control exists in S+ Engineering. Certain users now have certain rights.

The ability for user management is installed with the S+ Engineering Workbench. User management aligns itself to Role Based Access Control (RBAC), meaning the users have assigned roles in the system and those roles define the privileges a particular user has. With S+ User Management, the security administrator of a plant is able to define new users and associate these users to user roles. The predefined set of engineering user roles provided with S+ Engineering are as follows:

SPSystemAdmin – With this role, the user can create, delete and modify users and their associated roles access as well as assign users to specific projects.
SPEngineerAdmin – With this role, the user can create, delete, backup and restore S+ Engineering Harmony projects.
SPEngineer – With this role, the user can modify the configurations and conduct all standard engineering tasks, as well as create backups of assigned projects.
SPUser – This user can only view data.

2. Are there any other security features besides the Role Based Access Control?

Absolutely. S+ Engineering Workbench also features project mapping, which assigns specific projects to specific users. In some cases, there may be a common engineering workstation containing multiple units at a power station. Yet, the customer may only want to allow access to certain users in specific projects. To accomplish this requirement, S+ Engineering Workbench allows any project to be “mapped” to specific users with a simple drag and drop function available in the User management section of S+ Engineering Workbench.

3. Does S+ Engineering support PROFIBUS and HART fieldbuses?

In the S+ Engineering Workbench, Composer Field integrates field devices with PROFIBUS and HART technologies. Composer Field is a Field Device Tool (FDT) and supports configuration, commissioning, and maintenance of PROFIBUS devices using device type manager (DTM) technology. For field devices that have conventional device description files (GSD), a basic PROFIBUS DTM is available to allow standardized offline configuration. HART devices are integrated, configured, and parameterized through standard HART protocols without the need for additional tools by using a standard HART DTM. So yes, S+ Engineering does indeed support the HART and PROFIBUS fieldbuses.

Robert is a Senior Application Consultant, specializing in 3rd Party Interfaces for ABB’s Power Generation. He began his career at Bailey Controls as a configuration technician in 1990 and was promoted to System Engineer after receiving his Bachelor of Engineering degree in Electrical Engineering from ETI.

Robert expanded his real world field experience as an international independent contractor in 1996 where he commissioned an oil loading station based in Alexandria, Egypt. Returning to Bailey Controls in 1998, Robert took on the role as a Senior Engineer and was ultimately promoted to his current role of Senior Application Consultant. Robert will be celebrating the milestone of 25 years with ABB this August 2015.

Robert’s passion for 3rd Party Interfaces stems from the ever changing technology of today, which adds both challenge and excitement to his job every day. In his spare time, Robert can be found outdoors fishing, hunting, or playing a round of golf.
