New PLCopen Task Force to Focus on Safety
This new task force, TC 2 – TF Safety, has begun work on the definition of a Function Block Library for Safety Critical environments.
Its goals include providing an easy-to-use interface to the safety functionality and re-usability in a wide range of applications. It also seeks acceptance and/or approval of functionality and concepts by certification bodies, providing the basis for certifiable Function Blocks. It wants to provide a common basis, terminology, references, and a 'style guide' for additional and future Function Blocks.
During its first meeting, 12 potential function blocks were identified, as well as the operation modes. The four modes were manual, automatic, maintenance, and semi-automatic. The next meeting will be held on Monday June 23 at Siemens in Germany.
