CANopen-Specification for CANcockpit
Triggering Modes
The CANopen Communication Profile distinguishes two message-triggering modes:
Event Driven
Message transmission is triggered by the occurrence of an object specific event. In case of the CANcockpit the event
triggering is time-based.
Remotely requested
The transmission of asynchronous PDOs may be initiated on receipt of a remote request initiated by another device.
Pre-defined Messages
(Synchronisation-, Time Stamp-, Emergency Messages)
By means of Pre-defined Messages node synchronisation, time stamping and emergency notification is supported optionally.
Of these options the CANcockpit supports the emergency message.
Entries in Object Directory
Communication Profile Area
Device type (1000h)
The object at index 1000h describes the type of device and its functionality. The 32bit unsigned value is stored in ROM (read
only) and indicates the device profile, here "401=0191h" for generic I/O module supporting digital in- and outputs as well as
analogue I/O.
Value: 000F 0191
Error registers (1001h)
This object is an error register for CANcockpit. This entry is mandatory for all devices. It is a part of an Emergency object.
The error register is 8bit wide and coded as follows:
Bit M/O Meaning CANcockpit
0 M generic error Yes
1 O Current N/A
2 O Voltage N/A
3 O Temperature N/A
4 O communication error (overrun, error state) Automatic timeout function -> not required.
5 O device profile specific Reserved for future use (DS401)
6 O Reserved (always 0) 0
7 O manufacturer specific EEPROM checksum error
If a bit is set to 1 the specified error has occurred. The only mandatory error that has to be signaled is the generic error. The
generic error is signaled at any error situation.
Manufacturer Device Name Object (1008h)
Contains the manufacturer device name. It returns the visible string "CANcockpit".
