Chapter 1 ControlLogix EtherNet/IP Network Device Overview
CIP Security CIP Security™ is a standard, open communication mechanism that helps to
provide a secure data transport across an EtherNet/IP™ network. It lets
CIP-connected devices authenticate each other before transmitting and
receiving data.
CIP Security uses the following security properties to help devices protect
themselves from malicious communication:
• Device Identity and Authentication
• Data Integrity and Authentication
• Data Confidentiality
Rockwell Automation uses the following products to implement CIP Security:
• FactoryTalk® Services Platform, version 6.11 or later, with the following
components enabled:
- FactoryTalk Policy Manager
- FactoryTalk System Services
• FactoryTalk Linx, version 6.11 or later
• Studio 5000® Design Environment, version 32.00.00 or later
• CIP Security-enabled Rockwell Automation® products, for example, the
product described in this publication
For more information on CIP Security, including which products support CIP
Security, see the CIP Security with Rockwell Automation Products Application
Technique, publication SECURE-AT001
.
IMPORTANT
CIP Security is supported with the 1756-EN4TR, however, it is not yet
supported when the 1756-EN4TR is in redundant adapter mode.
If an 1756-EN4TR is installed and using CIP Security, and it is
reconfigured to be part of a redundant adapter pair, the module will
lose its CIP Security configuration. When this occurs, the I/O chassis
will lose communication with the controller.
At this point, the CIP Security policy must be redeployed.
