New and Updated CANopen Specifications
Erlangen (Germany). The CAN in
Automation (CiA) nonprofit organization has released several new and
updated CANopen specifications.
Most important is the CiA 311 XML
electronic data sheet (EDS) specification. It defines the XML scheme
to be used for the electronic description of CANopen devices. The
specification is based on the ISO 15745 standard. In the future, XML
electronic data sheets will substitute the well-known ASCII-based
EDS as specified in CiA 306. EDS are used by configuration,
diagnostic, or testing tools to get information about the CANopen
device to be configured, diagnosed, or tested.
The CiA 414-1/2 device profile
specifications describe the CANopen interface for weaving machine
feeders. They cover simple feeder devices as well as sophisticated
multi-feeder devices. “This device profile is the first for modular
weaving machines”, said Holger Zeltwanger, CiA Managing Director.
“We are going to develop further device profiles for modular
machines, e.g. for printing, packaging, and other industries.”
The CiA 425-2 profile for contrast media
injectors has been updated. The released version 2.0.1 is going to
be implemented by several American, European, and Japanese injector
manufacturers as well as by several companies producing image
processing medical devices. It is the first profile in the range of
add-on devices for computer tomography, magnetic resonator, and
angiography. It also could be used for ultrasonic devices.
The updated and reviewed CiA 303-1
recommendation describing the pin assignment for several connectors
contains the first Chinese connector. This 3-pin connector
(em069A-3) is dedicated to low-cost devices. The recommendation
contains more than 20 connectors to be used for CANopen devices.
