DHCP is another option for dynamically configuring the IP address of
the SLC 5/05 processor channel 1 Ethernet port (in addition to
BOOTP). When the SLC 5/05 is configured for DHCP, it will
broadcast a DHCP request at every power-up requesting that an IP
address be assigned to it. Any DHCP server that receives the request
can respond to it. The main difference between DHCP and BOOTP is
that while a BOOTP server will normally assign the same IP address
every time to a particular Ethernet device, based on its MAC address, a
DHCP server may assign any IP address from a pool of valid addresses.
This capability requires RSLogix 500 version 7.10 or higher software for
configuring.
• Secured processor capability using RSAssetSecurity
Using the RSAssetSecurity software service of the FactoryTalk
Automation Platform, RSLogix 500 version 7.10 or higher
programming software can configure a processor to be “permanently”
secured against future unauthorized programming software access.
Once secured, only users who have been authenticated and authorized
via RSAssetSecurity will be able to go online and upload/download this
processor using RSLogix 500 version 7.10 or higher. The only way to
unsecure a secured processor is to either disconnect the battery and
clear processor memory back to factory default, or to install a memory
module with an unsecured program configured to auto-load at
power-up.
The Secure Processor checkbox is found on the Controller Properties
General tab. A new read-only status file bit, S:34/8, reflects the secured
status of the processor (0=unsecured, 1=secured).
