Why can't all CAN IDs be used for CSMpressure, Lambda CANc and NOxCAN?
The modules CSMpressure, LambdaCANc and NOxCAN use the CANopen protocol. The CANopen standard already covers some IDs for internal communication purposes. For this reason, the entire ID range cannot be set.
Preallocated and therefore blocked IDs are the following:
| // Reserve 0x0 | --> NMT (network management) |
| // Reserve 0x80-0xFF | --> Error-messages |
| // Reserve 0x580-0x5FF / 0x600-0x67F | --> SDO communication |
| // Reserve 0x700-0x77F | --> Heart Beat |
| // Reserve 0x7E4-0x7E5 | --> LSS (Layer Settings Services) |
By default CSMconfig starts with the CAN-ID assignment at 0x600. As soon as CANopen modules are included in the configuration, the basic CAN ID shifts automatically to 0x680.
