NMT
NMT master/slaves
binary value (for bit coding), e.g. 0b0001 0000
decimal numerical value, e.g. 0d100
hexadecimal value, e.g. 0x64 (= 100 decimal)
transmission speed (1 baud = 1 bit/s)
CAN Application Layer
CAN-based network protocol on application level
Controller Area Network (bus system for use in mobile applications)
CAN-High; CAN connection /cable with high voltage level
CAN-Low; CAN connection /cable with low voltage level
CAN-based network protocol on application level with an open configura-
tion interface (object directory)
"CAN in Automation e.V."
(user and manufacturer organisation in Germany/Erlangen)
Definition and control body for CAN and CAN-based network protocols
Draft Standard (published CiA specification which usually has not been
modified or supplemented for one year)
Draft Standard Proposal (published CiA specification draft)
Work Draft (work draft accepted for discussion within CiA)
Specification for CANopen communication profile;
describes the basic communication between network participants, such as
the transfer of process data in real time, the exchange of data between
units or the configuration stage. Depending on the application this is com-
pleted by the following CiA specifications:
Device profile for digital and analogue I/O modules
Device profile for drives
Device profile for HMI
Device profile for measurement and control technology
Specification for interfaces to programmable systems (IEC 61131-3)
Device profile for encoders
Application profile for local public transport
CANopen Communication Object (PDO, SDO EMCY, ...)
CANopen Identifier of a Communication Object
the synchronisation time to be monitored, max. time between 2 Sync
objects
Emergency Object (alarm message, device indicates an error)
Error Register (entry with an error code)
Node or network participant could or can no longer be found
Guard Master: one or several slaves no longer reply
Guard Slave: no polling of the slave
During this time the network participant expects a "Node Guarding" of the
network master
Cyclic monitoring with parameter setting among network participants.
In contrast to "node guarding" no superior NMT master is required.
Identifier; identifies a CAN message. The numerical value of the ID also
contains a priority for the access to the bus system
ID 0 = top priority
see ID
index; together with the S index it forms the address of an entry in the
object directory
number of attempts in case of a missing Guarding reply
is used to describe the error class (guarding monitoring, synch etc.)
network management
The NMT master controls the operating states of the NMT slaves
