The programming

The FMSC system family has the right solution for each task. Compre hensive functions enable maximum flexibility with a convincing cost- benefit ratio. Examples:

Emergency shutdown (fast shutdown function) 

If the rather fast cycle time of the FMSC is still too slow, the hardware configurator can configure the emergency shutdown. The maximum switch-off time then is 0.5 ms. To ensure every single application has an optimal shutdown behavior, the emergency shutdown can be bypassed in the application program according to situation. This provides maximum flexibility regarding an emergency shutdown. 

Switch-off delay of outputs - also in case of a fault 

For many applications, the switching off behavior of safety controllers in case of a fault leads to risks for humans and machine. Conventional safety controls for internal or external hardware errors set all outputs to the secure state, resulting in the development of dangerous centrifugal forces. To exclude these hazards outright, the FMSC system family has a configurable switch-off delay for every single safety output. This specific type of shutting down offers protection from consequential damage. 

Speed monitor - safe, flexible and fast

The FMSC system family can safely monitor up to 16 axes. Different, pre-finished software modules cover any application as per EN 61800-5-2. For example, different speed profiles to be monitored can be allocated to an axis. Direction and standstill detection round off the requirement profile. Direction of rotation, resolution and sensor types can be simply and readily selected from the hardware configuration. The individual counter values are then processed further in the FMSC application program.

• Safe Stop 1: SSI
• Safe Stop 2: SS2
• Safe direction of movement (safe direction): SDI • Safe operation stop: SOS
• Safe speed monitor: SSM
• Safe speed range: SSR

Fiessler setzt mit der FMSC auf ein modulares Konzept

Im Gegensatz zu dem allgemeinen Trend, Sicherheitssteuerungen zu „brand labeln“, setzt Fiessler Elektronik auf eine komplette Eigenentwicklung der Steuerung. Durch den direkten Zugriff auf Hard- und Software kann die Sicherheits-SPS schneller angepasst werden.
