ODVA Publishes Revised Editions of Specifications for CIP Networks

December 16, 2007 // Published as a news service by IHS

These editions represent the second publication update of these specifications in 2007. The new editions include 23 specification enhancements, which include:

• Update of the EtherNet/IP specification with the latest in physical layer international standards provides specifications for industrially hardened cables and provides active interface design requirements for industrial interfaces while still supporting commercial products and interfaces.

  In line with international standards, a minimum of Category 5e cabling components is recommended. In addition, the specifications for the physical layer were made more comprehensive through the addition of support for physical media dependents (PMDs) such as twisted pair-physical medium dependent (TP-PMD) and fiber PMD.

• New device profile for an enhanced mass flow controller, which provides the instances and attributes necessary for the next generation mass flow controller devices including supporting both upstream process gas temperature and upstream process gas pressure in separate instances of the S-Analog Sensor object while allowing for future expansion of the profile.

• New media for CompoNet includes a 4-conductor round cable for use in IP67 environments simplifying CompoNet network power supply wiring by allowing communication signal lines and network power lines to be routed through one cable connected via a M8 or M12 connector.

The next publication of updated editions for the specifications is planned for the second quarter of 2008.
