5.3 HTTP SERVER AND ONDEMAND UTILITIES
Embedded in the BIS M-626-069-A01--06-ST31 is an HTTP Server, which provides a
Website-like interface and a suite of configuration tools.
Through the use of the BIS M-
626’s
HTTP 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 BIS M-626 to specific
Controller Tags as
defined in Rockwell Automation’s (
RA ) ControlLogix PLC.
CAUTION
Disable any firewall services affecting or running locally on the host
computer. Firewalls can potentially block communications between the
BIS
M-626 and the host and/or PLC.
NOTE
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 the Balluff approach to adding Change of State messaging to ControlLogix
and legacy support for RA PLC5E and RA SCL5/05 programmable logic controllers.
