The new FX5-SF safety control modules are SIL3, Cat4, PLe level safety devices for the most demanding applications. These modules greatly simplify the architecture between the PLC and Safety System. The safety data can be passed to the non-safe PLC code so external wiring is not required. The system is commissioned via a simple web-based configuration interface.
The following explains the features of a safety extension module.
■ Easy to construct a safety control system
A safety extension module can be attached directly to the iQ-F bus.
Therefore, only by connecting a safety extension module to a general control system, the conventional system can be expanded to a safety control system.
Additionally, each status of the safety control (such as safety inputs/outputs and error statuses) can be monitored.
■ Construct a safety system without programming
A safety control system can be constructed by selecting a built-in program of a safety extension module.
No sequence program for the safety control is required.
■ Easy to troubleshoot
When an error occurred on a safety control side, the error status can be easily checked in the monitor of GX Works3 or the module diagnostic screen; therefore, troubleshooting can be done easily.
Additionally, unlike a general safety relay and a safety controller, the safety wiring or setting of a communication gateway module to monitor the safety control status is not required because a safety extension module can be attached directly to the iQ-F bus.
