TheCommon Industrial Protocol(CIP) is an industrial protocol forindustrial automationapplications. It is supported byODVA. Previously known as Control and Information Protocol,[1]CIP encompasses a comprehensive suite of messages and services for the collection of manufacturing automation applications – control, safety, synchronization, motion, configuration and information. It allows users to integrate these manufacturing applications with enterprise-levelEthernetnetworks and theInternet. It is supported by hundreds of vendors around the world,[2]and is media-independent. CIP provides a unified communication architecture throughout the manufacturing enterprise. It is used inEtherNet/IP,DeviceNet, CompoNet andControlNet. ODVA is the organization that supports network technologies built on the Common Industrial Protocol (CIP). These also currently include application extensions to CIP: CIP Safety, CIP Motion and CIP Sync.
DeviceNetis a network protocol used in the automation industry to interconnect control devices for data exchange. It utilizes theCommon Industrial Protocolover aController Area Networkmedia layer and defines an application layer to cover a range of device profiles. Typical applications include information exchange, safety devices, and largeI/O controlnetworks.[1]
Usage: candump [options] <CAN interface>+ (use CTRL-C to terminate candump)
Options: -t <type> (timestamp: (a)bsolute/(d)elta/(z)ero/(A)bsolute w date) -H (read hardware timestamps instead of system timestamps) -c (increment color mode level) -i (binary output - may exceed 80 chars/line) -a (enable additional ASCII output) -S (swap byte order in printed CAN data[] - marked with '`' ) -s <level> (silent mode - 0: off (default) 1: animation 2: silent) -l (log CAN-frames into file. Sets '-s 2' by default) -L (use log file format on stdout) -n <count> (terminate after reception of <count> CAN frames) -r <size> (set socket receive buffer to <size>) -D (Don't exit if a "detected" can device goes down. -d (monitor dropped CAN frames) -e (dump CAN error frames in human-readable format) -x (print extra message infos, rx/tx brs esi) -T <msecs> (terminate after <msecs> without any reception)
Up to 16 CAN interfaces with optional filter sets can be specified on the commandline in the form: <ifname>[,filter]*
Filters: Comma separated filters can be specified for each given CAN interface: <can_id>:<can_mask> (matches when <received_can_id> & mask == can_id & mask) <can_id>~<can_mask> (matches when <received_can_id> & mask != can_id & mask) #<error_mask> (set error frame filter, see include/linux/can/error.h) [j|J] (join the given CAN filters - logical AND semantic)
CAN IDs, masks and data content are given and expected in hexadecimal values. When the can_id is 8 digits long the CAN_EFF_FLAG is set for 29 bit EFF format. Without any given filter all data frames are received ('0:0' default filter).
Use interface name 'any' to receive from all CAN interfaces.
candump -l any,0~0,#FFFFFFFF (log only error frames but no(!) data frames) candump -l any,0:0,#FFFFFFFF (log error frames and also all data frames) candump vcan2,12345678:DFFFFFFF (match only for extended CAN ID 12345678) candump vcan2,123:7FF (matches CAN ID 123 - including EFF and RTR frames) candump vcan2,123:C00007FF (matches CAN ID 123 - only SFF and non-RTR frames)
$ cansend vcan0 cansend - send CAN-frames via CAN_RAW sockets.
Usage: cansend <device> <can_frame>.
<can_frame>: <can_id>#{data} for 'classic' CAN 2.0 data frames <can_id>#R{len} for 'classic' CAN 2.0 data frames <can_id>##<flags>{data} for CAN FD frames
<can_id>: 3 (SFF) or 8 (EFF) hex chars {data}: 0..8 (0..64 CAN FD) ASCII hex-values (optionally separated by '.') {len}: an optional 0..8 value as RTR frames can contain a valid dlc field <flags>: a single ASCII Hex value (0 .. F) which defines canfd_frame.flags
$ cansend --help cansend - send CAN-frames via CAN_RAW sockets.
Usage: cansend <device> <can_frame>.
<can_frame>: <can_id>#{data} for 'classic' CAN 2.0 data frames <can_id>#R{len} for 'classic' CAN 2.0 data frames <can_id>##<flags>{data} for CAN FD frames

$ candump --help candump: invalid option -- '-' candump - dump CAN bus traffic.
