| + | {{:cbus:cbus-en.png}} | ||
| + | |||
| + | ==== CAN-ID ==== | ||
| + | The __**[[:cbus:flim-en#can-id|CAN-ID]]**__ used for the CAN Interface like CANGC1(e) and SocketCAN.\\ | ||
| + | |||
| + | ==== Sub-Library ==== | ||
| + | The connected CAN nterface: | ||
| + | ^ Type ^ BPS ^ Kit code ^ Manufacturer ^ Remark ^ | ||
| + | | TCP/IP | 10/100 MBPS | **[[:can-gca1e-en|CAN-GC1e]]** | GCA Peter Giling | Preferred. | | ||
| + | | USB | 500 KBPS | **[[http://www.merg.org.uk/merg_resources/cbus.php|CANUSB]]** | MERG | Preferred by MERG. The 12V version can be used in combination with the CAN-GCA line. \\ RTS/CTS should be disabled because its not supported by this module. | | ||
| + | | Serial | 230400 | **[[:can-gca1-en|CAN-GC1]]** | GCA Peter Giling | Uses **[[:cangc1-firmware-en#binary_response|binary responses]]** to improve through put. (Not MERG compatible.) | | ||
| + | | Serial | 115200 | **[[http://www.merg.org.uk/merg_resources/cbus.php|CANRS]]** | MERG | Deprecated; It is not fast enough to keep up with CBUS at full speed! | | ||
| + | | SocketCAN | - | | **[[https://github.com/GBert/misc/tree/master/RPi-MCP2515|RPi-MCP2515]]** | **[[https://en.wikipedia.org/wiki/SocketCAN|SocketCAN]]** compatible devices. | | ||
| + | \\ | ||
| + | |||
| + | ==== Device ==== | ||
| + | The serial device used for the CAN interface.\\ | ||
| + | ^ Kit code ^ Windows ^ Linux ^ Remark ^ | ||
| + | | CANUSB | COM5...COMn | /dev/ttyUSB0.../dev/ttyUSBn | | | ||
| + | | CAN-GC1, CANRS | COM1...COM4 | /dev/ttyS0.../dev/ttySn | An **[[:usb-rs232-en|USB-RS232 converter]]** can also be used. (Tested) |\\ | ||
| + | |||
| + | ==== Host/Port ==== | ||
| + | The hostname and port for the **[[:can-gca1e-en|CAN-GC1e]]** interface.\\ | ||
| + | In case of SocketCAN the host name is the device name. Default **can0**\\ | ||
| + | |||
| + | |||
| + | ==== Short events ==== | ||
| + | Use the short version of the accessory events; Event number only. (Recommended)\\ | ||
| + | The long events are based on node number and event number.\\ | ||
| + | |||
| + | |||
| + | ==== Fastclock ==== | ||
| + | Send **[[:cbus:can-gc7-firmware#opc|fast clock packets]]** on the CBUS.\\ | ||
| + | It is recommended to set this enabled in case of using a TCP/IP connection to prevent idle timeout disconnection.\\ | ||
| + | |||
| + | ==== Command Ack ==== | ||
| + | | :!: Use only in case of data loss in combination with WiFi. | | ||
| + | Activates the command acknowledgment handshake.\\ | ||
| + | A next command can only be send if the interface did acknowledged the previous command.\\ | ||
| + | This handshake prevents loss of commands due buffer overflow. (10/100MBit → 125kBit)\\ | ||
| + | Other manufacturers, like Lenz, are also using such a handshake on there Ethernet interfaces.\\ | ||
| + | | Only the **[[:cangc1e-firmware-en#binaries|CAN-GC1e version 1.c]]** is capable of handling this acknowledgment when this option is **[[:can-gca1e-en#setup|activated in the firmware]]**. |\\ | ||
| + | \\ | ||
| + | |||
| + | ==== FONFOF ==== | ||
| + | Use the OPC_DFON/OPC_DFOF instead of OPC_DFUN. (Not implemented by CANCMD.)\\ | ||
| + | |||
| + | ==== Heartbeat ==== | ||
| + | Sends every second an event# 4712 OPC_ACON/OPC_ACOF on the bus to be able to check for hardware/cable problems.\\ | ||
| + | The LEDs on the modules should flash every second.\\ | ||
| + | A CAN-GC2 can be programmed on this event# to be able to add a LED mounted on the dashboard.\\ | ||
| + | |||
| + | |||
| + | ==== SoD ==== | ||
| + | "Start of Day" address for query all input states.\\ | ||
| + | This must be programmed as event in all input nodes which should report.\\ | ||
| + | |||
| + | ==== Slot purge time ==== | ||
| + | CS timeout for updating DCC mobile decoders.\\ | ||
| + | If a loco becomes idle before this time out a keep alive command is send to the CS.\\ | ||
| + | :!: The hardware purgetime is 20 seconds, so this value should be **set to less then 20** to assure the slot is not purged during automatic runs!\\ | ||
| + | |||
| + | ==== Decoder check ==== | ||
| + | Check if all __**[[:accdec-gen-en|Decoders]]**__ are online. (NET-ID=CAN-ID, Bus=Node Number)\\ | ||
| + | The default interval is 10 seconds.\\ | ||
| + | A power off will be issued if a decoder is not responding. (Lost node.)\\ | ||
| + | Loco sessions will be invalidated if the GC3(CANCMD) was lost.\\ | ||
| + | | If a CAN-ID is found, which is not in the decoder list, it will be automatically added for checking. (It will be saved in the accessory decoder table, flagged as generated.) | | ||
| + | \\ | ||
| + | |||
| + | ===== FLAT Addressing ===== | ||
| + | mergCBUS addressing is **[[:addressing-en#flat_accessory_decoder_address_fada|FLAT]]**, __only the bus and address values are used.__\\ | ||
| + | ^ Rocrail ^ mergCBUS ^ Range ^Remark ^ | ||
| + | | - | CAN ID | 0...127 | Unique number within a CAN segment to be used in the CAN transport layer.\\ //This is the low part of the CAN **[[http://en.wikipedia.org/wiki/CAN_bus#ID_allocation|Message Identifier]]** without priority bits.// | | ||
| + | | Bus | Node number | 0...65535 | Used for **[[:cbus-en#short_events|long events]]** and **[[:cbus:flim-en|programming]]**. This must be set unique for all modules. | | ||
| + | | Address | Event number | 0...65535 | | | ||
| + | | Gate | Added to the address of output objects. | 0,1 | This is needed for signal pattern support. | \\ | ||
