Schneider CANopen Configuration tool for PLC islands.
BOOL
Boolean.
CAN
Controller Area Network : field bus originally developed for automobile applications and now used in many sectors.
CiA
CAN in Automation : international organization of users and manufacturers of CAN devices.
COB
Communication Object: transport unit on CANopen bus. A COB is identified by a unique identifier, which is coded on 11 bits, [0, 2047]. A COB contains a maximum of 8 data bytes. The transmission priority of a COB is given by its identifier. The weaker the identifier, the more the associated COB is priority.
COB-ID
COB Identifier : unique identifier of a COB on a CANopen network. The identifier determines the priority of a COB.
CSDO
SDO Client
DINT
Double integer : 32 bit word.
Discrete Module
Tout Ou Rien.
DS
Draft Standard: specifications document created by the CIA organization.
EBOOL
Boolean with edge detection and forcing possibilities.
EDM
Multi-language Electronic Data Sheet : extended version of EDS file. Extensions include European multilingual support as well as a description of physical characteristics of a device.
EDS
Electronic Data Sheet: Description of a CANopen device profile description normalized by the DSP306 CiA specification.
EMCY
Emergency : A trigger event, generated by an internal error/fault. This object is transmitted with each new error, since error codes are independent mechanisms.
ETS
Empty Terminal Support : Additional information is stored in the PLC application for uploading.
HEALTH
bit from 1 : Mode functions correctly
bit from 0 :
Bad configuration, or,
Module configured but absent, or;
module already configures, but with the same address as an existing module, or
No Communication
INT
Integer : Integer 16 bit word.
IODDT
Input/Output Derived Data Type
Mapping
Transformation of data consigned in a special and different format.
NIM
Network Interface Module : Communication between the device and field bus.
NMT
Network Management : This is responsible for managing the execution, configuration and errors in a CAN network.
PDO
Process Data Object: object for data exchange between different elements is CAN open.
PROCESS IMAGE
Part of the system memory where the E/S values are stored from PDO exchanges on the CANopen bus. This section is managed by the CANopen stack.
The inputs are copied in the user application memory at the start of each task cycle and the outputs at the end of each task cycle.
REAL
Real number.
RPDO
Received PDO
SDO
Service Data Object: peer to peer communication with access to Dictionary Object of a CANopen bus element.
