Simatic S7 F Systems engineering tool gains process safety functions
Siemens' Industry Automation Division has equipped its Simatic S7 F Systems engineering tool with new functions for safety-related applications in the process industry. The new software version V6.1 now features a Maintenance Override function for maintenance operations; automatically generated faceplates enable users to place bypasses in the safety program, which can be mutually interlocked if necessary. Bypasses can be placed both individually and at groups of up to three process signals. It is also possible to set a reset time so the bypasses automatically reset on expiry of the prescribed time period.Simatic S7 F Systems is an engineering tool that is provided with safety-related function blocks certified by the German Technical Inspectorate (TÜV). The function blocks are interconnected by users in CFC (continuous function chart) to create a safety-related program for the fault-tolerant Simatic S7-400H controller. This approach is said to be especially suitable for safety-related applications up to SIL3 according to IEC 61508 and IEC 61511 in the process industry.
