Scanreco SISP 4x3

Functional safety

SISP™

How do you design a solution to meet high levels of functional safety? At Scanreco we call our solution SISPTM, which stands for Scanreco Integrated Safety Platform. It's first of its kind modular safety solution developed in accordance with IEC 61508 and ISO 13849-1 safety standards. 


Flex and G6 series

SISP™ stands for Scanreco Integrated Safety Platform. It is a first of its kind modular safety solution, invented by Scanreco and approved by third-party (Rise Research Institutes Of Sweden) in accordance with the IEC 61508 (SIL3) and ISO 13849-1 (PLe) safety standards.

In short, dual micro processors in the transmitter, as well as in the receiver, work simultaneously at lightning’s speed to verify safe and correct functionality. It is a built-in standard feature in all models of the Flex series, including the Mini Flex, Micro Flex, and G6 CAN receiver.

How it works

Verification

Data verification process

Before the data generated from the actuator movement is transferred to the transmitter's radio module, it undergoes a verification process by a double set of processors on the transmitter mainboard. These processors work in parallel to check the data from several aspects, ensuring both speed and safety. Any minor unexpected deviation will cause the processors to reject the data package before it is transmitted.

When a command is performed on the transmitter, such as using a joystick or lever to make a movement on the machine, the signals are instantly encrypted before being sent via radio to the receiver on the machine.

Transfer

Data transmission

Once approved by the SISP™ module in the remote control, the information is forwarded to its radio module and sent to the receiver without delay, ensuring instant and smooth machine movements. The system can handle up to 1200 data transmissions per minute, which equates to 20 transmissions per second. The operator won’t ever notice what goes on.


Reception

Machine movement

At the other side, the receiver's mainboard instantly examines the information received as thoroughly as on the remote control before transferring the command to the machine. Any minor deviations or interference, will cause the SISP™ to reject the command and if no data is received for as little as 0.5 seconds, the SISP™ will shut down all safety-classified outputs, bringing the machine to a safe halt.
