The latest RC series 40 is a scalable platform of electronic control units for mobile machines. The freely programmable controllers allow safety functions up to PL d according to EN ISO 13849 or AgPL d according to ISO 25119. A hardware security module (HSM) is used to protect the control units from unauthorized data manipulation. The Rexroth controllers feature the UDS standard for the communication with a service tool. Interfaces for High Speed CAN, CAN-FD and ISOBUS are available. Future variants will also feature 100Base-T1 Ethernet.
