Software writers, network builders seek edge

The original DeviceNet technology has spread far and wide in over its 30 years of existence.
The purveyor of the fieldbus, the ODVA, opened its annual meeting Tuesday in Howey-in-the-Hills, Fla., with a series of closed-door special interest group meetings.
DeviceNet is a communication protocol used in the automation industry to interconnect control devices for data exchange.
It uses Controller Area Network, which debuted in 1983, as the backbone technology and defines an application layer to cover a range of device profiles.
ODVA (Open Device Vendors Association) manages the specifications and oversees conformance testing for DeviceNet and its other technologies including the Common Industrial Protocol, EtherNet/IP, CompoNet, ControlNet, and CIP Safety.
The full and public conference gets in full swing today with two conference tracks – marketing and technical.
Earlier this month ODVA and the TÜV Rheinland Group said TÜV Rheinland Japan would perform conformance tests for the organization.
Conformance testing is a necessary step required by ODVA of all vendors seeking ODVA Declarations of Conformity for their ODVA technology-compliant products.
“This cooperation is a natural extension of ODVA’s cooperation with TÜV Rheinland which began with CIP Safety and now includes testing partnerships in Japan and China,” said ODVA Executive Director Katherine Voss.
