1. Temporarily assign an IP address to the module using the Ethernet network For details see the TCP IP Ethernet Communications for the Series 90 PLC Station Manager Manual GFK 1541 Appendix D Proper IP Addressing is Always Essential The CPU374 s embedded Ethernet Interface must be configured with the correct IP Address for proper operation in a TCP IP Ethernet network Use of incorrect IP addresses can disrupt network operation for the CPU374 and for other nodes on the network Refer to the TCP IP Ethernet Communications for the Series 90 PLC User s Manual for important information on IP addressing Ethernet Programmer May Briefly Lose Communications When Configuration Stored Storing a PLC configuration containing Ethernet configuration values may require the Ethernet interface to restart itself in order to use any changed configuration values When the Ethernet interface restarts an Ethernet PLC Programmer briefly reports a loss of communications If this occurs the Ethernet Interface will post two or more PLC faults with the text LAN system software fault resuming and fault specific data starting with 080008 and or 080042 In addition faults with text Bad remote application request discarded request 1B0021 and Local request to send rejected discarded request 110005 may occur When these faults occur the STAT LED on the CPU374 is turned off to indicate posting of faults to the PLC fault tables In some cases a
2. 1 or to restart First PING Response Lost after Restart of Ethernet Interface Immediately after restarting the Ethernet Interface the first response to a PING large enough to require more than one IP packet 1466 bytes or larger is not generated Multiple Zero Period EGD Exchanges May Not Produce Similar Numbers of Samples If more than one EGD produced exchange is configured for a production period of zero the exchanges may not produce similar numbers of samples Due to the way that scheduling occurs when multiple exchanges are scheduled as fast as possible some zero period exchanges may produce significantly more samples than others EGD Performance Information Users requiring detailed EGD performance information should contact their Application Engineer and ask about the EGD Performance Application Note for the CPU374 Multicast Data Not Filtered The CPU374 does not do hardware filtering of multicast data over Ethernet This means that extraneous multicast messages on the network add an additional load on the CPU374 PLC and may significantly degrade performance Sufficient load can cause the CPU374 to reset its communication processor Changing IP Address While SRTP Connection Open May Generate Log Events SRTP connections established to the client are not terminated gracefully when the CPU374 s IP address is changed SRTP channels report either a 9690H or 0190H status and possibly remain open until the connections are termi
3. 10 second delay may occur before loss of communications is detected Normal operation resumes once the Ethernet Interface restarts The STAT LED can be reset using the Station Manager OK command When the PLC configuration is stored from an Ethernet PLC Programmer the communications loss occurs immediately after successful completion of the store Attempts to store configuration plus logic and or reference tables in one operation can fail However storing configuration separately from logic or reference tables always succeeds Store of Program or Reference Tables to Flash May Cause Loss of Ethernet Communications While storing the PLC program configuration and or reference tables from PLC RAM memory into Flash memory or to the EZ Program Store device Ethernet data communications may be lost Normal data transfers are temporarily suspended during a Flash or EZ Program Store device store operation In these cases Ethernet data transfers such as used by an Ethernet PLC Programmer connection will fail when the store exceeds the 16 second maximum period allowed for completion Upon completion of the store operation normal operation will resume If a timeout occurs during a store to Flash or EZ Program Store device the timeout value should be increased in the programming software being used See the User s Manual for the programming software for more details 4 Important Product Information GFK 2123E Ethernet Flash Test Failure The Etherne
