Plug-and-play USB

USB is the quickest way to access a drive.web device and network of drive.web devices that share the same Ethernet subnetwork.

Under the Directory menu, choose Discover via USB >

Local Device to discover just the USB-connected device.

By IP Address... to discover a single drive.web device that shares the same subnetwork as the USB-connected drive.web device.

Network to discover all drive.web devices that share the same subnetwork as the USB-connected drive.web device.

Some functions are not supported via USB:

Requires drive.web device firmware version 0x201A or newer. Please see Device Contextual Menu section of the user guide for more information.

Auto-discovery is not supported.

drive.web device IP addresses can not be changed via USB.

Windows 7 and OS/X support plug and play USB but contact us BEFORE connecting a drive.web device to a USB port on a WindowsXP computer.

drive.web Ethernet introduction

Ethernet supports drive.web distributed control and configuration and monitoring with savvy software.

Ethernet is the most common portal to the internet and the world-wide web.

Ethernet networks that enable drive.web communications may also be shared by other important elements including computers, printers and other controllers.

Understand some basic Ethernet facts to ensure reliability and avoid interference with existing systems that may be sharing the network:

The best way to ensure success is to work with with your company's IT department.

"IP Address" in this document refers to a 32-bit, internet protocol version 4 (IPv4) address.

IPv4 addresses are notated as four octets separated by dots. Each 8-bit octet may be any value from 0 to 255.

DHCP protocol is widely used and makes connecting new devices to an Ethernet network easy but it is not useful for a robust control system.

Assign a valid, static, unique IP address to each drive.web device.

Avoid duplicate IP addresses on a local area network

A valid IP address is typically within the subnetwork of all gateways, Ethernet switches and computing devices that will carry or process drive.web messages. In special cases drive.web messages may traverse gateways and the internet. Contact us for assistance with drive.web over the internet.

drive.web devices support advanced features that are outside of the scope of this document. See the savvy User Manual for details. Contact us for assistance with setting up SNTP network time server, SMTP mail server.

Discussion - subnetworks and subnet masks

Subnetworks help organize network traffic so that, in general, messages are only transferred within the same subnetwork. See the Wikipedia - Subnetwork Page for more information.

Subnet masks are applied to the most significant bits of a device's IP Address to effectively divide the address into two parts, the subnetwork prefix and the device address.

The prefix and subnet mask is often 24-bits meaning that the first 24 bits of the address of every device on the subnetwork must match and there are only 8-bits or 256 unique addresses to identify individual devices.

IP Address Subnet Mask Size Subnet Mask Notation Subnetwork Notation Valid addresses start with: Maximum number of devices:
Example 1 192.168.1.10 24 bits 255.255.255.0 192.168.1.0/24 192.168.1. 256
Example 2 192.168.1.10 16 bits 255.255.0.0 192.168.0.0/16 192.168. 65,536

The host computer can not communicate properly with drive.web devices unless they are in the same subnetwork.

drive.web devices support subnetworking but their subnet masks are generally left open with all zeros. Contact us for more information on applying subnet masks in drive.web devices.

Discussion - Local Area Network, LAN

A local area network is suitable for implementing drive.web distributed control systems. It is geographically limited, typically within one building. It is implemented with wired Ethernet and wi-fi wireless Ethernet.

drive.web devices use standard twisted-pair Ethernet to communicate at 10 or 100 million bit per second (Mbps) transfer rates. The terms 10BaseT and 100BaseTX are used to name these standards.

drive.web devices can be connected together in pairs with single cables but most typically via active Ethernet switches as part of larger networks.

A LAN may be connected to other networks via managed interface devices such as modems, gateways and firewalls.

Example 3- Choose valid, unique IP Addresses for a small, private Ethernet network

These links provide information on IP addressing for reference: RFC1918 Address Allocation for Private Internets, Wikipedia - IP Address Page

For most small, private networks requiring less than 65,000 unique addresses, use the IANA recommended 16-bit block 192.168.1.1 through 192.168.254.254.

Unless otherwise informed, plan to use the address space starting with 192.168.1.10. Assign this address to the host computer and then use subsequent addresses, 192.168.1.11 etc for the drive.web devices.

Follow these steps if no information on the network design is available from the IT department:

  1. Devices that are turned-off or in a sleep mode may cause problems when activated. Whenever possible, turn-on or activate all devices that may be connected to the network.
  2. Local area networks may have one or more DHCP server which automatically assigns IP addresses on request. Check the setup of DHCP servers. These are devices like dedicated firewalls, network servers and wireless routers. Avoid using addresses for drive.web devices that are within the ranges assigned by these DHCP servers.
  3. Use a command prompt or terminal window and the "ping" command as a final check to search the local network for other devices that may be using each chosen address:
    1. At a command line, type e.g. "ping 192.168.1.10".
    2. After several lines appear hold down the control key and press "c".
    3. The last response line should indicate the packet loss percentage. Any value other than 100% packet loss indicates that the IP address is being used. A different address must be found.
    4. Ping every address that will be used and ensure that the final response shows 100% packet loss.

Example 4 - Setting up a Windows 7 computer on a small private Ethernet network

The host computer may use DHCP to obtain its IP address automatically ONLY if there is a DHCP server on the LAN. If this is the case, stop after step 3 below and skip to the next section, back to savvy...

  1. Open the control panel and double-click the Network and Sharing Center icon.
  2. Click the Local Area Connection shortcut to see the status window -

  3. Important! - Click the Details button and make a note of addresses for future reference. Note - This information may also be obtained by typing "ipconfig" at a command line. (That is the preferred method for WindowsXP.)
    IPv4 Address. This is the current address.

    IPv4 Default Gateway and IPv4 DNS Servers. The computer uses this address to access the internet.

    Determine the computer's subnetwork. If the addresses chosen in example 3, above, are not within this subnetwork then either:

    Repeat the steps in example 3 using addresses within the computer's subnetwork or

    Multi-home the computer. Please refer to the First Time Network Administration page in the user manual for more complete information.

  4. If the computer's IP address will not be changed, skip the following steps and go to the next section.
  5. Close the details window and click on the Properties button.

  6. Click on the text, "Internet Protocol Version 4 (TCP/IPv4)" and then click the Properties button -

  7. As shown above, click the radio button, Use the following IP Address and enter the chosen address for this computer in example 3. Proceed with caution! Changing the computer's IP address can interfere with internet access and other network devices!
  8. Set the subnet mask according to example 1 or 2.
  9. Enter the Default Gateway and DNS server addresses noted in paragraph 3, above.
    Special note - leave these addresses blank or set to 0.0.0.0 when there is no connection to the internet available.
  10. Click OK in all of the windows opened in this sequence to complete setting the computer up with static IP addressing.

Now back to savvy, set up the drive.web devices' IP addresses

  1. Note - savvy must be set to the Administrate capability to change IP Addresses. Please see the Access Control page of the user manual for more information.
  2. Under the File menu, choose Administrate > Set IP Addresses for System -

    Note - this function uses link-local multicast on special IP address 224.0.0.189 to discover devices on the LAN that may be outside of the computer's subnet mask.
  3. Locate the devices in the list by their serial numbers. Note - the device serial number is also its MAC address number.
  4. Enter the new IP addresses chosen in example 3.
  5. Leave the Network Information box closed. Contact us for information on using this area.
  6. Click OK and the devices will appear in the savvy device directory.

See the savvy Directory section in the savvy User Manual for more information.

Add savvyPanel touch interface elements to the demo controller

In the next section we will go live with an actual smarty. savvyPanel will promote easiest control and monitoring of the essential parameters. savvy SFD upgrade is required to create savvyPanel tiles.

  1. Open savvyPanel in a new viewer window. Select File > New Viewer, then File > Open savvyPanel.
  2. There are two ways to create savvyPanel tiles.
    From a viewer window with SFD or function block view, drag and drop parameters over an empty area of the savvyPanel window and release.

    In the SFD or function block view, right-click on a parameter and choose Copy Parameter. Now right-click in an empty area of the savvyPanel window and choose Paste Parameter.

  3. Both actions above will open a savvyPanel tile selector. Feel free to try the different tile choices. Remember drive.web devices must have dwOption-26 to display the full set of tiles.
    Create tiles for the following parameters in the demo smarty: From Waveform Generator add Period and Amplitude.

    From PID add Proportional Gain, Integral Time, Error and Integral Term.

    From T14 Analog Output, add Monitor.

Set up a Parameter Dock and take the PID controller live

Parameter docks must be saved in the host computer. They are not stored in the drive.web device. They are often used for convenience in troubleshooting and for gathering and displaying trend data for a given set of parameters.

To illustrate dock trend features use a live smarty.

  1. Export the configuration from the phantom to a file in the host computer. Right-click on the smarty icon and choose Export Device Data.
  2. Delete the phantom from the directory. Right-click on the smarty icon and choose Delete.
  3. Connect a smarty onto the host computer's subnetwork and discover it. Choose Discover Local Devices Now under the Directory menu.
  4. Right-click on any parameter in the smarty and choose Add to Parameter Dock. We are particularly interested in the dynamic signals at the Waveform Generator and after processing in the PID, but feel free to add as many parameters as you like to the dock.
  5. Add the parameters to a dock; Waveform Generator > Output and T14 Analog Output > Monitor

A PID controller acts to minimize the error between Setpoint and Feedback. The PID reacts strongly to reduce the error from the Feedback produced by the Waveform Generator if the Setpoint at smarty's T13 Analog Input remains at a constant value.

You may find the instant, graphic feedback from a dock to be a valuable learning tool for the complexities of the smarty's standard PID function block.

Start with a small and slow waveform. Using savvyPanel, set the Waveform Generator Period to 20 seconds and the Amplitude to 10%

Choose Show Trend under the Dock menu.

Choose Timespan > 1 minute under the Dock menu.

Right-click in the trend area to get a contextual menu including access to the instaneous Trend Point Info for the point in time that you right-clicked on. The color legend is also shown.

Dock trends give instant feedback to changing parameters. Try increasing the proportional gain in the PID.

In trend mode you can find various choices for exporting the data under the Dock menu.

Multiple dock windows are possible. Just open a new viewer window and add parameters to it. Always remember to save your docks for later use. Use Save as... under the File menu.
