New extension modules for integrated safety

Mitsubishi Electric has introduced compact, fully integrated units which are designed to streamline installation and configuration while improving data visualisation and integrity

Mitsubishi Electric's newly launched FX5-SF-MU4T5 main module and FX5-SF-8DIA input expansion module facilitate the introduction of smart safety operations on the factory floor. The new products are said to enhance the capabilities of MELSEC iQ-F FX5U and FX5UC PLC CPUs for applications that require compliance with Category 4, PLe or SIL3 international safety standards.

The new FX5 safety extension modules are claimed to be easy to set up as they do not require any programming. They feature a rotary switch that allows users to select from nine types of built-in safety logic, removing the need to load or develop any sequence, allowing shortened commissioning times.

The safety modules are connected to the PLC via a bus cable without the need for specific communications modules, allowing users to reduce their wiring and equipment footprint. The direct transfer of safety information to the main CPU is also enabled by the connection, which can then conduct advanced diagnostics.

With built-in web server functions, the system data can be displayed on any device via a web browser and visualisation can be readily provided with an HMI. In some cases the solution can help businesses achieve system validation for cGMP compliance. Users can take advantage of these options to monitor the status of both standard and safety control systems simultaneously. 

A web browser based configuration guidance app helps to confirm the resulting configuration and wiring. In addition, the tool produces an impression of the safety standards that the set-up meets, assisting businesses in reaching the configuration that is required for their application. Once the set-up is complete, it is also possible to print the documentation generated and use it for library functions.

Finally, the FX5-SF-MU4T5 and FX5-SF-8DIA modules, coupled with the web server functions, support operational integrity. During runtime users are instantly notified of any tampering of the logic set on the rotary switches and these activities do not affect the integrity of the safety system.
