Product Information

Intended Use of the Product

The EchoRing Ethernet Bridge (device) enables a time-critical and reliable wireless link between Ethernet-based industrial protocol devices. It can be employed for:

• Replacing cable-based network infrastructure with a wireless connection in machinery, vehicles and devices, enabling simplified infrastructure and flexible operations.
• Replacing network cables between moving structures or components in machinery, vehicles and devices in order to reduce weight, size and use of installation space, as well as wear and tear on network infrastructure.

ATTENTION — This radio device is intended for transmitting data wirelessly. It is furthermore intended to be used for low latency and/or high reliability data communications. When using device, be mindful of the general behavior and physics of the wireless channel. Abrupt or predictable changes in the operational environment, such as movement of people or objects, and the presence of interfering devices, can result in reduced wireless signal quality and failed data transmissions. Thus, when used in critical applications, where the result of poor wireless connectivity can cause severe human injury or economic damage, intended operations cannot rely solely on this device. A comprehensive system solution, such as an integrated wired failsafe in case of poor wireless connectivity, must be installed and tested to the level of intended application’s importance.

Web-based Configuration Interface

General Information

The Web-based configuration interface is used for configuring, deploying and re configuring devices.

Set Up and Access Web User Interface

1. Arrange and connect a PC, the Config Server and the devices, intended to be in the same network cell, to the network switch according to the following diagram:

Figure 5-I: Config setup

2. Ensure all Ethernet cables are connected, and that all devices are powered on.
3. Open the PC’s network settings and configure the static IP address 10.10.100.99 and the subnet mask 255.255.0.0.
4. Open a web browser and enter the URL http://10.10.100.100

ATTENTION — The web-based user interface is designed for the web browsers Firefox (version 60 or newer) and Chrome (64 or newer). Other browsers may not support full functionality.

Configure the Device

1. Set up and access the Web User Interface (see Section 5.2).

2. In Web User Interface, take a look at ”Echoring Deployment”. Connected devices are shown in the paring view there. Click the IP address to pair all devices or click each device to include/exclude it.

3. Click the ”Configure Deployment” button underneath to continue.

4. Please determine the MAC address of the device to be connected and enter it to the right of the device’s (Node) IP address.

5. The “Capacity Factor” configures the number of available transmission slots of the device, allowing for greater data rate (throughput), asymmetric traffic, or synchronicity optimization per device – in relation to overall network capacity (which is configured later).
   TIP — To derive the required capacity factor for each device, simply analyze the traffic and corresponding data rate each device transmits, in relation to all devices in network. Then portion out capacity factors accordingly.
   EXAMPLE — 3 devices have a combined network data rate of 200 kb/s,

6. device has 2 capacity factors = 100 kb/s,

7. devices have 1 capacity factor each = 50 kb/s each

8. Apply prioritized traffic filter (if needed) in bottom field under “Priority Traffic” by entering the prioritized data’s “byte index”, counted from the start of the MAC header, and its “Byte value”
   **EXAMPLE — Profinet:

To filter for additional/other packet aspects, such as IP addresses, packet flags, QoS fields or similar, add additional entries to the prioritized traffic filter.
TIP — Filter entries work as AND function, meaning data to be prioritized must match all entries.
TIP** — Data to be transmitted is buffered in a queue and transmitted when its device’s transmission slot arrives. If the application has multiple traffic types – such as critical control/safety packets or best-effort packets – they can be prioritized via a filter. Packets matching the filter will be buffered in an alternate queue and sent prior to packets in the main queue. If no prioritized traffic is set, all data is treated as equally critical.

7. Click the EchoRing tab and set the parameters to match the application data and the wireless settings.

(A) Channel: the radio frequency to operate on.

TIP — To prevent interference, please ensure that any other radio transmitting device does not operate on the selected channel. Please see to our product portfolio for tools that can help you plan and enable coexistence of wireless products.

(B) TxPower: the power that each device shall transmit with.

TIP — Some milliwatt (mW) to decibel-milliwatts (dBm) conversions are 0dBm=1mW, 10dBm=10mW, 14dBm=25mW.

(C) Reliability: the level of reliability mechanisms activated for the EchoRing protocol.

TIP — In order to make sure network is configured to allow application traffic’s cycle time, packet length and data rate, it is recommended to start with minimum reliability first and then go back and increase reliability after all parameters been set

terms of throughput and lower latency.
8 (maximum)| Maximized reliability measures, often resulting in less performance in terms of throughput and latency.

( D ) Optimize For: by selection one of the three alternatives; Reliability (C), Packet Length (F) and Latency (G), this one selected parameter will be given best possible value automatically pending on the other parameters input value. Exact Config disable this function.

(E) Base Data Rate: is the shared data rate among all devices that can be achieved with the current setting.

TIP — A Base Data Rate value can be given as an input, helpful in cases when the network throughput requirement is more primary than for example a specific Packet Length.

(F) Packet Length: the maximum expected packet length. Packet Length must be dimensioned to include all protocol headers. Telegram example with a UDP payload:

ER Fragmentation (4B)| Ethernet (14B)| IP Header (20B)| UDP Header (8B)| Usable payload (100B)
---|---|---|---|---

TIP — Prioritized Packets (F) that are longer than the Packet Length configured will be discarded. Non-prioritized packets can exceed the configured Packet Length and will be then fragmented.

(G) Latency: The duration within a packet transmitted must be received (cycle time).

(H) Targeted Token Rotation Time: The duration it takes for a station that has transmitted a packet to deterministically be allowed to transmit once more.

EXAMPLE — If the application traffic has a cycle time of 16 ms (packets received later may cause application stop), the system should ideally be configured with a Targeted Token Rotation Time shortly below 8 ms, to allow timing jitter.

TIP — If the application’s data rate exceeds the maximum throughput set by the latency, packet length, reliability parameters or each device’s configured capacity, the system becomes overloaded and the packets risk being dropped, leading to packet loss. The prioritized traffic filter (step 6), allows a wider latency threshold to be set for specific packet types.

(I) Security: the level of security to protect traffic integrity.

Click ”Deploy configuration” to input the configuration into the devices.

Power cycle the devices and disconnect from the switch.

Connect each device to their respective, MAC-address configured, device(s)

Replace an Ethernet Bridge™

To replace a device, all devices in the pertaining network must be reconnected and then reconfigured with the replacement device, according to the procedure in Section 5.3 above.
