Byte Command Protocol Binary commands

The Byte Command Manual describes the commands and their structure of the Proemion Byte Command Protocol to used by a remote host and the CAN network for message transmissions.

General

The Byte Command Manual describes the structure and commands used by the Proemion Byte Command Protocol.
This protocol is supported by all CAN to PC gateways from Proemion GmbH for communication with a remote host via the interface supported by the device.
The following manual extends the device specific manuals.
In case of uncertainties please also refer to the device manuals of your specific gateway device.
The CAN to PC gateways connect a CAN network to a remote host using a specific interface like RS232, USB, Ethernet, Bluetooth or WLAN.
The Proemion Byte Command Protocol serves for bi-directional transparent CAN message transmission between the host and the CAN network as well as for the transfer of commands between host and gateway.
Since all Proemion CAN to PC gateways work on the same protocol, any application software can be easily extended to use different communication interfaces by just exchanging the basic communication routines.
Most of the commands are supported by all gateways, in some cases special commands are not supported by single devices.
The table in chapter Commands and Devices gives you an overview on the commands supported by each single gateway-type.

NOTE
Normally all commands which influence devices settings are only stored in the volatile RAM memory of the gateway, after a reset the settings stored in the devices non-volatile memory are used again.
You can change these settings with the device specific configurator software or – if supported by the device – via CANopen.
Exception: The command “CAN baud rate” is stored permanently.
For some gateways it is possible to change start-byte (default: 0x43) and stop-byte (default: 0x0D) in the configurator software.
All descriptions in this manual assume that the default values are used.
For further information and support fill out the support form, see Service and Support.

‘C’ (0x43) is the default setting. For some devices this  value can be changed. This manual always  shows the default setting.
Length| 0x00-0xFF| The  length byte includes the number of data bytes the number of command bytes following.

2.6.4. CAN controller reset

Byte(s) Value Description

SOF
(Start of Frame)| 0x43| SOF marks the beginning of the command.
Length| xx| The  length byte contains the number of data bytes the number of command bytes following.

Checksum| xx| Contains the XOR checksum of the SOF, Length, Command and the Data-bytes.

NOTE
The “CAN Controller Reset” command performs a complete reset of the CAN controller, including the timestamp value, receive and transmit buffers.
The CAN controller reset also resets the error status of the device.
For this reason, after the CAN controller reset, an error status message is generated, to update the error status.
The usage as extended command is possible (see Extended Command Format (Byte Mode)).

2.6.5. Set CAN interface Auto Baud Mode

Byte(s) Value Description

SOF
(Start of Frame)| 0x43| SOF marks the beginning of the command.
Length| xx| The  length byte contains the number of data bytes the number of command bytes following.
Command| 0x59| Set auto baud mode (no additional data bytes)
Checksum| xx| Contains the XOR checksum of the SOF, Length, Command and the Data-bytes.
EOF
(End of Frame)| 0x0D| EOF byte marks the end of the command.

NOTE
Auto Baud Mode is only possible with the standard baud rates the device supports.
For auto baud detection it is necessary to have a working communication on the bus.
While baud rate detection is active, the Proemion CAN devices are in passive mode and have no influence on the traffic on the CAN bus.
The usage as extended command is possible (see Extended Command Format (Byte Mode)).

The auto baud command sets the gateway device to “Auto Baud Mode”.
The device listens to the traffic on the CAN and configures the baud rate automatically (only standard baud rates supported by the device are detectable).
After getting the right baud rate setting, the device generates a reply, containing the detected baud rate.
The format of this message is identical to the CAN baud rate request message, except the command byte is 0x59.
When no baud rate is detected, the device uses the last configured baud rate for operation.
In this case, the baud rate reply is the same as if a nonstandard baud rate is requested.

If the “Timestamp-Mode” is selected, a 32-bit counter (100 µs resolution) value is inserted after the last data byte of each received CAN message.
All messages on the host interface side which contain a timestamp are in the correct chronological order.
If a timestamp should be inserted after the echoed messages (“Transmit Server Feedback” or “Send CAN Message Feedback”) and the error messages, the ‘Error and Echo Feedback timestamp’ has to be activated additionally.
The difference between “relative” and “absolute-mode” is that the counter value is reset after each received message in “relative-mode”.

The “Error and Echo Feedback” timestamp is only transmitted if the timestamp mode is enabled.
The usage as extended command is possible (see Extended Command Format (Byte Mode)).
