Use the Multifunctional Access Box in an
Integrated Safety Controller-based System
Set the Network IP Address The access box ships with the DIP switches set to 0 and DHCP enabled.
Perform one of these steps to set the network IP address:
• Adjust the DIP switches inside the access box (see Figure 19 on page 35
).
• Use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation BootP/DHCP Server Utility.
• Retrieve the IP address from nonvolatile memory.
The access box reads the switches first to determine if the switches are set to a
valid number. Set the network address by adjusting the eight DIP switches
inside the access box. Valid settings range from 001…254.
When the switches are set to a valid number, the IP address of the access box is
192.168.1.xxx (where xxx is the decimal representation of the binary number set
on the switches). The subnet mask of the access box is 255.255.255.0 and the
gateway address is set to 0.0.0.0. When the access box is reading the network
address set on the switches, the access box does not have a host name assigned
to it or use any Domain Name System.
If the switches are set to an invalid number (such as 000 or a value greater than
254), the access box checks to see if DHCP is enabled. If DHCP is enabled, the
access box requests an address from a DHCP server. The DHCP server also
assigns other Transport Control Protocol (TCP) parameters.
If DHCP is not enabled, the access box uses the IP address (along with other
TCP configurable parameters) stored in nonvolatile memory.
See Figure 16 on page 22
for an example of the network address DIP switches.
ATTENTION: Set a suitable network IP address before connecting the access
box to a network.
