Module 8 Serial Commu Features of the RX3i Ethernet Interface include: The Ethernet Interface implements the capabilities of a Class 1 and Class 2 device. WInLoader is supplied with any updates to the Ethernet Interface software. Built-in Station Manager for on-line supervisory access to the Ethernet Interface. Dedicated Station Manager port.
Internal network switch with Auto negotiate, Sense, Speed, and crossover detection. Recessed Ethernet Restart pushbutton to manually restart the Ethernet firmware without power cycling the system. Yes — Allows daisy chaining of Ethernet nodes. RS DCE, – bps. This firmware is available in upgrade kit 44AG The Ethernet Interface no longer gives nuisance faults when connected to certain network devices, such as hubs that do not complete speed negotiation in ms or less.
Resetting the Ethernet Interface returns it to normal operation. The loopback IP address New Features for this Release Release 3. The Channel Commands are: Establish Read Channel Establish Write Channel Send Information Report This is a local command: The interface also allows for a way to specify all channels be aborted.
Retrieve Detailed Channel Status These connections are not shared with any other applications. If the local IP address has changed, any existing open TCP connections are unable to normally terminate. Gfl Ethernet Interface sometimes generates multiple gf log events and PLC Fault Table entries when a single error condition occurs.
When large numbers of EGD exchanges 2224 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 client applications should be designed to take this variance into account. This fault is a nuisance fault and may be ignored.
This fault can be safely ignored.
Note that by doing so, EGD exchange production may be delayed. This can cause unexpected channel timeout errors H or H at the client. When these configuration values are changed, the effect is not immediate.
The amount of partial ggk written depends upon the starting bit memory location and the data length as follows: To avoid writing partial data to the local or remote PLC, be sure bit memory data transfers do not exceed the configured reference memory sizes at the appropriate PLC.
Subsequent Hardware Configuration store will have the producer ID reported correctly. In all cases, there is no permanent damage and the system defaults to a safe status. Cycling the power restores normal system operation. See Field Service Bulletin M The RX3i Ethernet module may not recover from a power cycle event on rare occasions approximately once out of several-hundred events.
There is no permanent damage and cycling the power again restores normal operation. If time synchronization is not configured for the Ethernet Interface, it loses time at gck rate of approximately 0. This log event can be safely ignored. On the RX3i Ethernet module, the state of the pushbutton when the module powers up can change ggk behavior of the Restart pushbutton.
Under normal operation, a pushbutton press produces a rising-edge signal that triggers a module restart. However, if the pushbutton is pressed when power is activated either by pressing the pushbutton before turning power on or by continuing to hold the pushbutton in after a restartthe functionality of the pushbutton is inverted.
When the pushbutton is later released, an “incorrect” rising-edge is detected, which triggers an inappropriate module restart. The Ethernet addressing information must be configured prior to actual network operation, or to recover from inadvertent changes to the Ethernet addressing data at the Ethernet Interface.
Use one of the following methods to initially assign an IP address: Once a temporary IP address has been set up, the Ethernet Interface can be accessed over the network by the Machine Edition programming software. The programmer should then be used to configure the proper IP address for the Ethernet Interface. Machine Edition programming software maintains the target IP address used to connect the programmer to the target independent of the contents of the HW Configuration for that target.
To regain communication at the former IP address, use the manual corrective action grk above. Storing a HW Configuration containing default 0. The default IP address value 0. Cables may be shielded or unshielded.
It is important to realize that the two ports are connected to an embedded network switch. There is not a separate IP address for each port. The hub or switch connections in an Ethernet network must form a tree and not a ring; otherwise duplication of packets and network overload may result.
In this situation, the RX3i Ethernet modules will continually reset. Before manually configuring duplex mode for a PACSystems RX3i port using Advanced User Parameters AUPbe sure that you know the characteristics of the link partner and are aware of the consequences of your selection.
If its link partner is not similarly manually configured, this can result in the link partner concluding an incorrect duplex mode. The IEEE standard says: This eliminates the need for crossover cables when connecting directly from the port s to a hub yfk a switch.
If speed and duplex mode of a port are forced using AUP, the gfj will no longer perform automatic cable detection. This means that if you have the switch port connected to a switch or a hub port you must use a crossover cable.
GE RX3i User Manual
You must use a normal cable if you have the switch port connected to the uplink port on a switch or hub, or if you have the switch port connected to another Ethernet device.
Cable detection does work if only speed or duplex, but not both, is forced. If more than one EGD produced exchange is gkf for a production period of zero, the exchanges may not produce similar numbers of samples.
If more than 24 SRTP Server connections are established simultaneously, EGD Production may be briefly ggfk for each connection after the 24th when the connections are first made after power is applied.
Examples are establishing the TCP connection for a new channel, establishing communication with the remote device, and TCP retransmissions during Channel operations. If the time needed for TCP connection establishment or maintenance exceeds the user-specified channel application timeout values, an application timeout will occur.
Channel application timeouts fgk temporary errors; the channel continues to run. There is a period of time that the OS Network stack hangs onto the TCP resources associated with a connection after it is closed. Application developers using client channels need to be aware of this behavior when designing logic.
There are a finite number of TCP resources allocated to client channels, and if channel connections are brought up and down so fast that these resources are depleted, the application may have to wait until a TCP resource frees up to establish another client channel A COMMREQ Status of 0xA is returned if no TCP resources are currently available; the application should wait then try again.
One can also specify a number of iterations, or run forever.

However, re-tasking to a different remote device does not conserve TCP connections, or save on the time it takes to create a channel. The default value of the tfk timer for the Series 90 modules is set to a fgk higher value than gfo the PACSystems.
With this change, TCP connections remain open indefinitely. This also applies to SRTP Client Channels that have infrequent traffic and can be resolved by using the same technique. If more than the maximum 16 supported Modbus Server Connections are attempted, the TCP connection may succeed, but no data may be subsequently transferred. Be sure to observe any additional ratings that are provided with the modules.
