ContentsChapter 1 Introduction Contents Ethernet Global Data Timing ContentsTroubleshooting a Ladder Program ContentsTroubleshooting Common Ethernet Difficulties A-3Advanced User Parameter Definitions It describes features of the Ethernet Interfaces in both conventional andredundancy systems.

Chapter 11, Network Administration discusses how devices are identified on the networkand how data is routed among devices. Appendix A, Configuring Advanced User Parameters describes optional configuration ofinternal operating parameters used by the Ethernet interface.

For most applications, thedefault Advanced User Parameters should not be changed. GFK - D In addition to these manuals, datasheets and update documents describe individual modulesand product revisions. The most recent PACSystems documentation is available online atwww. Thegateway IP address must be configured. Yes — Allows daisy chaining of Ethernet nodes. The port automatically senses the speed 10Mbps or Mbps , duplex mode half duplex orfull duplex and cable straight-through or crossover attached to it with no interventionrequired.

Typical switches, hubs, or repeaters support 6 to 12nodes connected in a star wiring topology. Two pairs of wire are used, one for transmission,and the other for collision detection and receive. Typical switches, hubs, or repeaters support6 to 12 nodes connected in a star wiring topology. WInLoader is supplied with any updates to the Ethernet Interface software.

WinLoader seamlessly upgrades first the CPU firmware and thenthe embedded Ethernet firmware without user intervention. You store the web pages to the Ethernet interface via FTP. Rackbased Ethernet Interface modules do not provide Web Server capability. Any givenchannel can be assigned to only one protocol at a time.

Both Produced and Consumed exchanges can be configured. The two modules are in twodifferent PLCs that are configured as a redundant system. Both the active and backup unit may continue to use their individual direct IP addresses,permitting programmer connection to the active or backup PLC at any time. Effect of Redundancy Role Switching on Ethernet Communications When a redundancy role-switch occurs, Ethernet communications switch to the backup unit,which has no knowledge of any communication state at the previously-active unit.

Theapplication must include logic to detect loss of communication during a redundancy roleswitch and to then reinitiate communication. To remote hosts on the network, the redundant system is viewed as a single PLC with highreliability; the remote host neither knows nor cares which PLC is the active unit.

By using theRedundant IP address, the remote host always communicates with the active unit. When aredundancy role switch occurs, the for merly-active PLC gives up ownership of the Redundant IP address and takes down all connection-oriented communications currently using theRedundant IP address. The programmer can still communicate directly with each PLC in the redundant system for example, to store new logic or configuration using the direct IP address of each Ethernet Interface.

The backup unit does not respond to the Redundant IP address. Both the active and backup units maintain SRTP Server connections at the direct IP address for network communication with the programmer. Other remote hosts should use theRedundant IP address when communicating to a redundant system. That will prevent temporary resource problems when establishing new SRTP Clientconnections to the new active unit while the previous connections to the old active unit arebeing taken down.

The backup unit does not respond to theRedundant IP address. Remote hosts should use the Redundant IP address when communicating to a redundantsystem. When the active Ethernet interface changes to backup, it takes down all Web Serverconnections and their underlying TCP connections.

The Web Server maintains its underlying TCP connection only long enough to process each web page request; a new TCP connectionis opened, used, and closed for each subsequent web page display or update. So unless aweb page change or update is requested during the redundancy role switch, the operation ofthe Redundant IP address is transparent to the Web remote browser. Any web page requestin process over the Redundant IP when a role switch occurs is terminated.

Although not recommended, the remote browser may issue Web Server requests to the direct IP address. Both the active and backup units respond to Web server requests received at thedirect IP address. Remote web browsers are expected to use the Redundant IP addresswhen communicating to a redundant system. SNTP operation isunaffected by the current Ethernet redundancy state or by redundancy role switches.

Station Managerresponses from the Redundant IP address can be misleading because it is difficult todetermine which Ethernet interface is actually responding. Ethernet Restart Pushbutton3. There isonly one interface to the network only one Ethernet address and only one IP address.

Seechapter 10 for blinkcode definitions. During normal operation and while waiting for an IP address, the LAN LED blinkswhen data is being sent or received over the network directed to or from the Ethernet interface.

It remains on when the Ethernet interface is not actively accessing the network butthe Ethernet physical interface is available and one or both of the Ethernet ports isoperational. It is off otherwise unless firmware update is occurring. This LED is on for normal operation and flashing for allother operations. When a hardware or unrecoverable runtime failure occurs, the EOK LEDblinks a two-digit error code identifying the failure. For a list of blink codes and their meanings,see chapter This LED is lit if the networkconnection at that network port is Mbps.

This LED is lit when the link isphysically connected. It blinks when traffic is detected at that network port. Traffic at the portdoes not necessarily mean that traffic is present at the Ethernet interface, since the traffic maybe going between ports of the switch. It is recessed to prevent accidental operation. Restart Pushbutton Operation for Version 3. The duration that the Restart pushbutton is presseddetermines the operation after the restart occurs. To restart the Ethernet interface normally, press the Ethernet Restart pushbutton for less than5 seconds.

If the Ethernet interface uses any optional Ethernet plug-in applications, these applicationsare ordinarily started upon each powerup or restart. To restart the Ethernet interface withoutstarting any Ethernet plug-in applications, press and hold the Ethernet Restart pushbuttonbetween 5 and 10 seconds. To restart the Ethernet interface into firmware update operation, press and hold the Ethernet Restart pushbutton for more than 10 seconds. This is typically done during troubleshooting tobypass possibly invalid firmware and allow valid firmware to be loaded using WinLoader.

Pushbutton-controlled restart operations are listed below, with the LED indications for each. Restart OperationRestart the Ethernet interface normally, and startany optional Ethernet plug-in applications that arebeing used.

Restart the Ethernet interface without starting any Ethernet plug-in applications. Restart the Ethernet interface into firmware updateoperation. Once the firmware update actually begins, the existing firmware iserased and the Ethernet Restart pushbutton is disabled until the firmware update is complete. Restart Pushbutton Operation Prior to Version 3. This could cause the CPUto Stop, damage the module, or result in personal injury. The label is visible when the battery is removed from itscompartment.

The battery does not need tobe disconnected to temporarily remove itfrom the compartment. Connect the battery to either of the batteryconnectors on the module. Put the toggle switch in the STOP position. Make sure that rack power is off.

Install the CPU module in slot 1 of rack 0. Press the module firmly in place, but do not for ce the board. Tighten the screws on thetop and bottom tabs. Connect one or both of the Ethernet ports onthe Ethernet Interface to the network. Turn on power to the PACSystems rack. The label is visible only with module out of therack. Be sure the rack power is OFF. Slide the module into the slot for which it wasconfigured in the system.
