VMIVME-7700-111000 combustion engine card

The RX7i does not log an exception or a fault in the PLC Fault Table when it detects a duplicate IP address on the network. REPP Does Not Save Results of Aborted PING The station manager REPP command does not retain the results of a PING that is aborted due to error. The PING results are reported when the PING is aborted, but subsequent REPP commands give the results of the last successfully terminated PING. Multiple Log Events The Ethernet Interface sometimes generates multiple exception log events and PLC Fault Table entries when a single error condition occurs. Under repetitive error conditions, the exception log and/or PLC Fault Table can be completely filled with repetitive error messages. Intermittent SNTP Loss of Synchronization Under moderately heavy EGD traffic load, the Ethernet Interface may occasionally lose synchronization with its SNTP time server and generate exception log event 29, entry 2=bH. Reduced EGD Consumption with Large Numbers of Produced Exchanges When large numbers of EGD exchanges are produced at a rapid rate, some consumed EGD exchanges may exhibit lower rates of consumption than expected. To better balance produced and consumed EGD exchange performance, reduce the number or frequency of the produced exchanges configured at this Ethernet Interface

SRTP Communication Delays

 Average latency of communications on SRTP channels may vary considerably due to TCP retransmissions. SRTP client applications should be designed to take this variance into account. In particular, SRTP client applications migrating from Series 90-70 SRTP Servers to RX7i may need to lengthen SRTP timeout parameters. PLC Fault Table Last Update Date and Time The PLC Fault Table web page does not display the correct data for the PLC date and time field. The date and time displayed are the PCs local date and time, not the PLCs date and time. Spurious ‘Ethernet Failure’ Error On rare occasions, the error “Module hardware fault” may be reported on the Ethernet daughterboard. The corresponding fault in the exception log is Event = 1, followed by text "Ethernet failure". This fault is a nuisance fault and may be ignored. Web Server Failure Under Heavy Load After several hours of heavy load on the web server, the web server may fail to return pages and may cause a LAN system-software fault to be logged. The web server will resume serving pages when the load is reduced.

Reference Table Web Page Restriction

 After the user selects a user defined table, if the user then tries to go back to the predefined table of %R1-%R60, an error message may be displayed stating “An error was detected when trying to retrieve setting from PC cookie”. Fault Table Web Page Restriction On both the I/O and PLC Fault Table web pages, the PLC program name is not currently displayed in the area provided. Cannot Set FTP Password The CHPARM TPASSWORD Station Manager command fails. Processing an AUP File containing parameter “tpassword” generates an error. Reference Table Web Page Format When using Netscape 4.7 to view the reference table web page, the size of the columns is incorrect. The first column is much wider than the others.
