The Open DeviceNet Vendors Association (ODVA) will publish updated editions of specifications for the family of Common Industrial Protocol (CIP) Networks.

The updated specifications for EtherNet/Internet Protocol (IP), DeviceNet, CompoNet, ControlNet and CIP Safety technologies include new capabilities that are designed to extend device interoperability and application coverage, said ODVA.

The following features will be included:

  • CIP Safety on DeviceNet and CIP Safety on EtherNet/IP. Introduced in 2005, CIP Safety is certified to be compliant with the functional safety standard International Electrotechnical Commission (IEC) 61508 up to safety integrity level (SIL) 3.

    The latest edition of this specification includes new functionality to support network features needed in process and Supervisory Control And Data Acquisition (SCADA) applications as well as installations using wireless.

    These features include increased granularity in error detection and more flexibility in configuring safety reaction times.

  • Integration of Modbus serial devices into CIP Networks. Modbus translation services for Modbus Transmission Control Protocol (TCP) devices were added to CIP in the previous editions of the specifications published in November 2007. In these editions of the specifications, a new "serial link object" was added to round out the Modbus translation services supported by CIP.

Collectively these revised editions of the specifications include 18 enhancements. The specifications are organized as a group of publications entitled the CIP Networks Library. Each specification is made up of one or more volumes of the CIP Networks Library.

The latest editions of the specifications are:

  • EtherNet/IP Specification comprised of the CIP Networks Library: volumes one (Edition 3.4), two (Edition 1.5) and seven (Edition 1.1).
  • DeviceNet Specification comprised of the CIP Networks Library: volumes one (Edition 3.4), three (Edition 1.5) and seven (Edition 1.1).
  • ControlNet Specification comprised of the CIP Networks Library: volumes one (Edition 3.4), four (Edition 1.1) and seven (Edition 1.1).
  • CompoNet Specification comprised of the CIP Networks Library: volumes one (Edition 3.4), six (Edition 1.3) and seven (Edition 1.1).
  • CIP Safety Specification comprised of the CIP Networks Library: volume Five (Edition 2.1).
