CIP™
The CIP (Common Industrial Protocol) feature allows N-Tron Series switches to directly provide switch information
and configuration access to Programmable Logic Controller (PLC) and Human Machine Interface (HMI)
applications via a standardized communication protocol. For example, a PLC may be programmed to monitor port
links or N-Ring status and trigger a status indicator to turn red on an HMI if a port goes link down or if N-Ring has a
fault. CIP is formally described in ODVA Publication Number PUB00001 (Volume 1: Common Industrial Protocol
(CIP)), and Publication Number: PUB00002 (Volume 2: Ethernet/IP Adaptation of CIP). Red Lion created EDS and
ICO files are provided with the NT24k switch series.
Note:
Information about using CIP with the NT24k can be found in the CIP User Manual & Installation Guide
and the CIP Installation Kit for the NT24k switch family.
1.2.13
PTP
Precision Time Protocol (PTP), IEEE 1588v2, is supported on licensed NT24k models. PTP allows users to
configure a network with very accurate, coordinated timing among devices. NT24k models with software
implementations of PTP are capable of achieving microsecond level accuracy. PTP is disabled by default and can
be enabled as a Boundary or Transparent clock through the Web Browser interface. The switch must have a valid
PTP license installed before PTP can be enabled.

Dynamic
Host
Configuration
Protocol
(DHCP)
DHCP (Dynamic Host Configuration Protocol) simplifies network configuration by automatically assigning IP
addresses from a DHCP server to connected DHCP capable devices (DHCP clients). NT24k switch configuration
options include:
•
DHCP Server
•
DHCP Relay Agent
•
DHCP Client
1.2.15.1
DHCP
Server
DHCP Server allows DHCP Client devices to automatically obtain an IP assignment. IP assignments can be
set up as a dynamic range of IP addresses available to any client device; or specific IP addresses based on
the clients Client ID (Option 61), or Relay Agent connection (Option 82). It also allows for a device on a specific
port to receive a specific IP address and if the device is replaced, the replacement receives the same IP
address as the original device.
1.2.15.2
DHCP
Relay
Agent
DHCP Relay Agent (Option 82) allows communication between the client and server to cross subnet and
VLAN boundaries.
