Appendix A Configuring Advanced User Parameters
Advanced User Parameters (AUPs) are internal operating parameters used by the Ethernet interface. For most
applications, the default AUPs should not be changed.

Note The RX3i CPE330 (Release 8.60) and CPE400 (Release 9.15) adds support for the following EGD AUP
parameters via the Embedded Ethernet interface’s hardware configuration:
gp_phase – startup delay time (in msec) for successive produced exchanges.
gnostale – handling of stale consumed exchanges:
0 = send stale status to application
1 = do not send stale status to application.
gucast_ttl – TTL for unicast messages
gmcast_ttl – IP time-to-live for LAN1 host group (multicast) messages (hop count). New
parameter that replaces the gXX_ttl for each multicast group on LAN 1.
gmcast_ttl2 – IP time-to-live for LAN2 host group (multicast) messages (hop count). New
parameter.
gXX_addr – Multicast group IP address for LAN 1. New parameter.
gXX_addr2 - Multicast group IP address for LAN 2. New parameter.
Note: CPE330 and CPE400 do not support AUP files. All the configurable AUP parameters for
these CPUs are part of the hardware configuration for the corresponding Embedded
Ethernet interface in PME.
If it is necessary to modify any of these parameters, it must be done by creating an AUP file, using any ASCII
text editor. This file must contain the names and values of only those parameters that are being changed. This
user-generated AUP file is then imported into the programmer and assigned to a particular Ethernet Interface.
To modify Advanced User Parameters in more than one Ethernet Interface in the same control system, import
an AUP file for each Ethernet Interface. If the changes are identical, you can use the same AUP file for more
than one Ethernet Interface.
When the entire hardware configuration is stored from the programmer to the CPU, the programmer also
stores the parameters from all assigned AUP files. The CPU delivers any assigned AUP file data to its Ethernet
Interface along with its configuration. AUP file data is transferred along with the rest of the hardware
configuration during both download (programmer-to-CPU) and upload (CPU-to-programmer) operations. AUP
file data is also included in the configuration Verify operation between programmer and CPU. Note that there
may be a separate AUP file for each Ethernet interface (or some may have them while others do not).
If an Ethernet Interface is not configured by the programmer, its Station Manager can be used to locally modify
the Advanced User Parameters for that individual module. (Setting the IP address/subnet mask via BOOTP or
the “SetIP Tool” does not qualify as a programmer configuration.)

The RX3i CPE305/CPE310 embedded Ethernet interface does not support the full set of AUPs described in this
chapter. For a list of AUPs supported by the RX3i embedded Ethernet interface, refer to page 258.
