May 1, 2012 - In February 2006, PLCopen published their Safety Specification Part 1 - Concepts and Function Blocks for Safety Functions. Since then it became obvious that additional functionalities were needed. The additions are partly dealt with in a new document: Part 3 – Extensions to the Function Blocks. These new function blocks extend the scope of the specification, and harmonize the diagnostics interface for easier handling by the user.
This new specification has now been released for comments until June 22, 2012 as version 0.99.
