Pilz has released version 6.0.0 of the PNOZmulti Configurator software package for use with the PNOZmulti modular safety controller. It is available in English and German, plus a new feature enables diagnostic messages for end users to be created offline in any language and imported into the Configurator.
The multifunctional PNOZsigma relay allows a smaller number of units to be used in applications that previously required the use of numerous different models of safety relay, meaning that stockholdings can be reduced substantially. The PNOZsigma relays also provide LEDs on the front that give much better diagnostic data than their predecessors, helping with troubleshooting and therefore reducing machine downtime.
Systems for thermal exhaust purification are subject to furnace regulations, and the safety of such plants presents a particular challenge for automation technology. In the past, the safety functions on systems manufactured by Dürr were monitored using conventional automatic gas burner control systems and safety relays, but safety and efficiency have since been greatly improved with the implementation of advanced safety control systems.
New digital technology now makes it feasible to integrate process control and safety instrumented functions within a common automation infrastructure. While this can provide productivity and asset management benefits, if not done correctly, it can also compromise the safety and security of an industrial operation. This makes it critically important for process industry users to understand where to draw the line. Cyber-security and sabotage vulnerability further accentuate the need for securing the Safety Instrumented System (SIS).
It’s often a requirement of many manufacturing processes to have the operators become directly involved in the machine action at the unloading point, either to unload or secure the outbound product. Unfortunately, the outfeed sections of most processes are notoriously dangerous, so in reality we should be striving to remove the operators from the area at all times.
The demand for safety technology in bulk liquid storage plants is increasing worldwide. This market trend can clearly be seen in tank gauging projects where Safety Integrity Level (SIL) requirements are now being incorporated.
The Neles ValvGuard VG9000F for Foundation Fieldbus is claimed to be the first TÜV-approved (SIL3) Foundation Fieldbus (FF) safety valve controller to appear on the market. It combines the benefits of FF communication with the Neles ESD valve range to provide a new level of integrity and safety.
