recommended
Restrictions and Open Issues
When a produced EGD exchange is added or modified by a Run-mode
Store, the exchange will not be produced until one production period of
time has elapsed after the completion of the run-mode store.
When initiating ICMP echo requests from the PLC via the Station
Manager's PING command, the operation occasionally fails and an
exception is logged (Event eH, Entry 2 = 6H).
The EGD Station Manager "referr" tally may be incremented twice when
an exchange timeout occurs. Exchange status word reporting works
correctly and is not affected.
Zero is allowed for the "wkal_idle" (TCP keepalive timer) but it is an invalid
value.
If the TCP connection timeout is set higher than 10 minutes, the
connection may timeout before the configured value. The connection
timeout is derived from three AUP parameters: wkal_idle + (wkal_cnt + 1) 
wkal_intvl.
Ethernet Operational Notes
User should change the station manager password to other than the
default password. The remote station manager access is disabled until the
station manager password is changed to other than the default password.
The station manager password can be changed using an AUP file. (Refer
to Appendix A, Configuring Advanced User Parameters in TCP/IP Ethernet
Communications for PACSystems User's Manual, GFK-2224K.)
GE Intelligent Platforms strongly recommends that you change the Station
Manager password to a value other than the default. Before a
configuration has been stored to the CPU, you can change the password
by using the CHPARM command to modify the Advanced User parameter
(AUP) stpasswd. For details on using this command, refer to the Station
Manager Manual, GFK-2225.
It is not recommended that you change any AUP other than stpasswd.
Use the current password to access the Modify level of the Station
1.
Manager. The default password is system.
Change the password.
2.
Example: = chparm stpasswd newpass
Restart the Ethernet interface or cycle power. Changes made via the
3.
CHPARM command do not take effect until the Ethernet interface is
restarted or power is cycled. Advanced User Parameters are saved in
non-volatile memory. Changes made by the CHPARM command are
retained over restart and power cycles, until changed again by the
CHPARM command.
To permanently change the Station Manager password, you must
4.
change the stpasswd parameter in the AUP file. See the TCP/IP Ethernet
Communications for PACSystems User's Manual, GFK-2224 for details.
(After the CPU configuration has been stored into the CPU, the CHPARM
command is prohibited and any previous changes made with it are no
longer effective.)
