SIEMENS’ Industry Automation Division says it has equipped the Simatic S7 F Systems engineering tool with new functions to simplify maintenance operations.
Simatic S7 F Systems is an engineering tool that is provided with safety-related function blocks certified by the German Technical Inspectorate. The function blocks are interconnected by the user in Continuous Function Chart to create a safety-related program for the fault-tolerant Simatic S7-400H controller.
According to Siemens, version V6.1 software for the Simatic S7 F Systems features a Maintenance Override function for maintenance functions. Users can place bypasses in the safety program which can be mutually interlocked if necessary.
Bypasses can be placed both at individual 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.
