Common Industrial Protocol Safety

Common Industrial Protocol (CIP) Safety is a set of extensions to the CIP that enables the safe operation of devices. It also provides fail-safe communication between different nodes on a CIP network.

The CIP Safety protocol comprises two main components:

• CIP Safety segments—Used in Forward Open messages to exchange safety parameters for the subsequent safety session.

• CIP Safety messages—Used to exchange actual safety information.

The CIP inspector detects and identifies:

• CIP as a service and client

• Payloads, such as CIP Read, CIP Admin, CIP Infrastructure, and CIP Write

  The CIP inspector can parse the CIP segments and detect the CIP Safety segments in the Forward Open requests.

To test the CIP Safety feature, you must enable the CIP inspector. See Detect and Block Safety Segments in CIP Packets.
