COBALT UHF-SERIES CHAPTER 6: ETHERNET/IP INTERFACE
PAGE 90 OF 140
Sections 6.3 through 6.7 contain instructions that will help you accomplish the
following:
Assign the Cobalt an IP address via HTML Server
Configure the Cobalt’s Subnet Node via OnDemand Utilities
Create “Controller Tags” in the PLC
Verify PLC and Cobalt Subnet Node connectivity
6.2 HTML SERVER & ONDEMAND PLC SUPPORT
Below is a partial list of the programmable logic controllers that are supported by
EMS’ HTML Server and OnDemand Utilities.
ControlLogix – OnDemand supports all current versions
RA’s PLC5E releases:
Series C, Revision N.1
Series D, Revision E.1
Series E, Revision D.1
PLC5 "Sidecar" Module Series B, Revision A with EIP support
SLC5/05 releases:
Series A with firmware revision OS501, FRN5
All Series B and Series C PLC Controllers
6.3 HTML SERVER AND ONDEMAND UTILITIES
Embedded in the Cobalt UHF-CNTL-IND-02 is an HTML Server, which provides a
Website-like interface and a suite of configuration tools.
Through the use of the Cobalt’s HTML Server, users can access, modify and save
changes to the unit’s Industrial Ethernet configuration, IP address, and OnDemand
mode settings.
The OnDemand Utilities will be used later in this chapter to link the Cobalt to specific
Controller Tags as defined in Rockwell Automation’s (RA) ControlLogix PLC.
ATTENTION: Disable any firewall services affecting or running locally on the host
computer. Firewalls can potentially block communications between the Cobalt and the
host and/or PLC.
ADDITIONAL INFORMATION: In ControlLogix, a “Controller Tag” is a small block of
internal memory that is used to hold outgoing (command) and incoming (response)
data. Within each controller tag, information is stored in two-byte segments, known as
registers or “words.”
OnDemand is Escort Memory Systems’ approach to adding Change of State
messaging to ControlLogix and legacy support for RA PLC5E and RA SCL5/05
programmable logic controllers.
