Leroy Automation offers programmable computers in accordance with the EN50155 / IEC 60571 standard to perform the control functions of a TCMS.

They are based on the generic platform “RIOM”.

The RIOM can be operated as:

-a central computer (VCU )
-a communication gateway between fieldbuses and the Ethernet network
-a local automation system to control subsystems (HVAC, doors, braking, power-packs, fire safety, …)

The RIOM is designed to be able to be integrated into SIL2 architectures.
