Abstract
A control system for control of components in mobile hydraulic equipment, the control system being in the form of a CAN system and comprising modules controlling the components and a bus connection. A signal mirroring unit is provided via which the modules are connected to the bus connection. The signal mirroring unit reflects signals generated internally in the module back to the module and prevents the signals from appearing on the bus connection, at least during an activation phase. This allows the control system to operate disruption free.
Claims20
A control system for control of components in mobile hydraulic equipment, said control system being in the form of a CAN system and comprising:
- modules controlling said components;
- a bus connection;
- and
- signal mirroring means, via which said modules are connected to said bus connection, for reflecting signals generated internally in one of said modules back to said one of said modules and for preventing said signals from appearing on said bus connection, at least during a connection phase, whereby said control system functions disruption free.
A control system for control of components in mobile hydraulic equipment, said control system being in the form of a CAN system and comprising:
- modules connected to a bus connection in said control system, each said module having a receiving and a transmitting state;
- an acknowledgement generator arranged in each said module and generating an acknowledgement signal inside said module, each said module being arranged to reflect said acknowledgement signal inwardly so said acknowledgement signal does not reach said bus connection.
