Device List Options - Obvius, LLC A7810 Installation And Operation Manual

Note: not all Modbus devices have built in driver support in the AcquiLite. If a device appears in the list with "Unknown" in
the status column, you may need to upgrade the firmware on the AcquiLite to access the device. At the bottom of the device
list page under the Type column, a link is shown that will show all the Modbus devices with built in driver support provided
in the firmware. Use the System/Firmware update page to check for newer versions of the firmware. The Obvius.com
website faq also has a list of supported Modbus devices. Modbus devices that are not supported by built-in drivers may be
configured using the Modbus Framework feature in the AcquiLite.
At the bottom of the device list, there is an option to allow you to rename all the devices listed. This is useful for initial
deployments. There is also a troubleshooting link that will look for common configuration problems and alert you to the
appropriate solution.

Device List Options

At the top of the Modbus device list page, there are several display options that control the sorting of the device list.
Tree display: Click this icon to organize the list by showing each ModHopper, and the devices attached to each one.
List display: (default) Show the list of Modbus devices sorted by the Modbus address number.
At the bottom of the Modbus device list, there are several options that may be selected to view or configure all the Modbus
devices at the same time. These options are as follows:
Add: Manually add a Modbus device to the device list. This option can be used to configure a Modbus device that is not
presently connected to the system, add a framework configured device, or add a Modbus/TCP connected device. See the
section on manually adding a device below.
Troubleshoot: The AcquiLite will review the devices connected and offer suggestions about any problems found.
Rename all devices: This option allows you to edit all the device names in one configuration page. This is useful when
initially configuring a large number of new devices. A name must be assigned to a device before the AcquiLite will log data
for it.
List all supported devices: This option will show a list of all Modbus devices with built in drivers in the installed firmware.
Show [setup]: Display links for Device configuration and Advanced configuration for each device.
Show [devinfo]: Display the communications options including baud rate, serial number and firmware version (when
available) for all devices in the Modbus device list.
Show [stats]: show packet counters for all devices in the device list. These include
Sent: Total number of packets sent to this Modbus address.
Received: Total number of valid packets received from this Modbus address.
Error: Total number of packets received that fail CRC for this device. (does not include non-response queries)
RTT: The average round trip time for the last 7-10 packets that received a valid response. This value is useful
in configuring the Modbus timeout in the Modbus Setup page. Note: if the timeout is set too short, you will
not see an accurate value because packets dropped for timeout are not counted for RTT.
XML: Display the device list data in XML format.
