SiloTrack Inventory Management Software

SiloTrack™ Inventory Management Software Version 3.5 is the next evolution of Monitor’s popular PC-based application software that provides users with an unsurpassed, flexible graphical interface for our industry-standard SiloPatrol® SE Model SMU inventory monitoring sensors and our Flexar® guided wave radar continuous level measurement sensors. Refer to bulletins 343P (SMU) and 353P (Flexar) for more information.

SiloTrack software includes a Server and Client version. Together SiloTrack Server and Client provide inventory monitoring and management capability to a virtually unlimited number of users. Users can be internal and external to your facility, allowing you to easily implement remote inventory monitoring and vendor managed inventory.

The SiloTrack Server software is the master operator interface for our SiloPatrol SE and Flexar “smart” sensors. This software is installed on the PC in which the RS-485 communication sensor network(s) will be connected. All application setup and configuration is done with the Server software.

The SiloTrack Client software provides remote users access to the inventory monitoring system and can be installed on PC’s that can interface with the SiloTrack Server PC via LAN, WAN/Internet or Dial-up modem. Security is established in the SiloTrack Server software. The type and method of connection is established in the SiloTrack Client software. The SiloTrack Server software allows you to establish security for access by any Client user.

Auxiliary Output Enclosures (AOE) and Remote Display Units (RDU) can be added to make any SiloTrack system a true management and control system (RDU’s can not be used with Flexar level sensors). Relay action and analog outputs are easily setup in the SiloTrack Server software.

Software Displays & Capability

SiloTrack™ software, like other Windows® based programs, offers simple and intuitive operation. There are multiple ways to access and change setup parameters, or perform system functions. You can activate functions from the drop down lists of the Menu Bar topics, or by left-clicking the mouse on the Tool Bar icons.

Setup Wizard

It is very easy to build vessel graphics using the unique Setup Wizard in the Server software. SiloTrack also includes a self-explanatory tab structure system, which makes it simple to configure alarms and relays, select sensors, select units of measurement, etc. The Setup Wizard in the Client software makes it simple to connect to the Server PC, subscribe to silos, and receive measurement updates.

With no prior experience, and with minimal help from the Installation & Operation manual that comes with the software, you should become comfortable with the operation of SiloTrack within 30 to 60 minutes – its that simple.

SiloTrack Server and Client software incorporate both English and Spanish languages. The primary display and configuration text is English. Conversion to Spanish is easily accomplished. All Help files are only in English.

The main display screen for the SiloTrack Server and Client software allows the operator or user to graphically view the last status condition of each silo and its material contents. Using your PC’s mouse you can highlight a silo (left click on the image) and display the detailed information for the selected silo in the Silo Details screen (left panel in main display as shown below).

Silo Inventory Main Display

SiloTrack has the ability to have up to five sensors per vessel. Very large vessels, or vessels that may have multiple inlet and/or discharge points may require more than one sensor for higher precision in the distance measurement. The total distance measured by all sensors is divided by the number of sensors to derive the average distance to the material in the silo. The distance measurement can then be used to calculate the level, volume and weight of material. Measurement units can be selected from a wide variety of English or Metric units. Sensor status condition and diagnostic messages are displayed for each silo ("Ready"; or a specific error message will be shown in red).

Up to four alarms can be established for each silo and can be individually named and set to activate as a high or low level alarm, sensor error or material reorder alarm. Changing alarm or relay set points is easy. Just "click and drag" alarm and relay indicators to change their respective set points. It's that simple.

Each alarm can be set so that specific actions are taken when alarm conditions exist. Alarm notifications can be sent to: up to two e-mail addresses(or Text messages to cell phones), up to two fax numbers, and up to two pager numbers.

The material reorder alarm is a low level alarm that can provide notification to a selected vendor that this specific silo is in a reorder condition, thereby informing your vendor to take action based upon your pre-arranged instructions.

The number of silos that can be setup and displayed on a single page is limited by the size of each silo and the arrangement that you create. You can size and locate vessel graphics using the “click and drag” function with your mouse. Multiple pages can be used to organize your graphics by material type, location or any other logical method you might want to use.

The easy-to-use Menu Bar at the top of the main display allows you to quickly setup the software for your specific application. In addition, the "Tech Support" menu button can be used to link to the Monitor website, view Installation & Operation documents or to chat with a technical support specialist if the PC is connected to the Internet.

Convenient Tool Bar buttons (including the button for the Set-Up Wizard) are provided just below the Menu Bar. These buttons will allow you to quickly initiate common Windows® commands plus make a manual measurement for a single silo or all silos. You can also view the selected silo history graph and silo properties. SiloTrack Inventory Management Software is truly the easiest to use and the most flexible and capable operator-interface of its kind.

While you can use our unique SiloTrack Setup Wizard as previously mentioned, silo graphics can also be established by left-clicking on the "Add Silo" Tool Bar button or by entering the "Silo" menu and clicking on the menu item "Add" (shown at right). This will automatically place a silo graphic on the main display screen. All the information about the silo can then be easily entered in the "Properties" window, which is accessed under the "Silo" menu or via the convenient silo properties button.

The silo setup in the properties window includes Sensor Selection and Address, Silo Name and Material Contents, Display Default, Measurement Method (manual, auto or auto/manual),, Automatic Measrement Settings, Measurement Units (English and Metric), Silo Type, Dimensions and Material Bulk Density, Curve-Fit Weight Data Table Setup (if used), Alarm 1, 2, 3 and 4 Setup, %Display, Analog (one per sensor) and/or Relay outputs (up to four per silo), Material and Empty Space Colors, and External Silo Colors for 3D image.

Material volume and weight can be calculated and displayed if desired. SiloTrack Inventory Management Software offers you the ability to display volume/weight calculations based upon either geometric calculation using the silo type, dimensions and bulk density information you have entered, or based upon the data you enter in the Curve Fit Weight Table. The weight table allows you to enter up to 100 data pairs, each consisting of a distance measurement and a corresponding weight value. Actual distance measurements between data points will result in a weight value displayed based upon a standard curve fitting equation. The Curve Fit Weight Table is a tool you can utilize if you wish to improve the precision of the weight calculation.

SiloTrack Inventory Management Software can generate standard reports for Measurements (silo history, silo last measurement, page summary and all summary) and Sensor Diagnostics (Server software only), which can be scheduled for transmission via email or fax automatically. This feature can be used to notify material suppliers of a replenishment need or to provide management with necessary information reports automatically at scheduled times or intervals.

Each user can export silo history data or alarm data into any one of several available formats. This allows you to save data files for further manipulation and analysis.

In addition, the silo history or alarm data can be viewed in chart form. A selected date range is entered and the silo measurement data (display default) is charted. The history data chart can be printed and the data tabulated in a report and exported and printed.

The SiloTrack Inventory Monitoring Client Software can be setup to access silo data from one or multiple SiloTrack Server locations via direct dial-up, LAN or Internet/WAN connections. This allows remote location applications to be implemented including vendor managed inventory, remote corporate access, and bulk transport monitoring and scheduling. This improves communication and can eliminate downtime and out-of-material conditions. The Set-Up Wizard in the Client software can be used to create new pages, set-up communications with the Server PC, set-up password security, determine how to receive measurement updates, and select the desired silos to monitor.

In addition, alarm alerts can automatically notify remote users or suppliers of material level via email and fax. Reports can also be automatically generated and sent.


Remote Access System Security

Access to the SiloTrack™ Server software database is controlled by establishing a unique user name and password for each Client. A virtually unlimited number of individual Client/users can be established. User groups can also be setup.

Each client can be restricted to have access to a limited subset of the total number of silos connected to the SiloTrack Server system. Each Client can also be restricted to “read-only” or can be allowed to manually initiate measurements.

For LAN/Internet/WAN applications, when requesting an update or adding silos to the Client software, the Client can be required to identify the name or IP address of the PC which contains the SiloTrack Client software and transmit that address along with the client’s unique user name and password.

For dial-up remote monitoring connections additional security can be enabled by selecting the dial-back option. This selection in the Server software requires entry of a phone number that the SiloTrack Server software PC will call in response to the dial-up request. This provides added security to ensure that only the target remote user will receive the update.

Communication between Client and Server software is further protected by a 56-bit encryption algorithm.


Use of Volume/Weight Calculations

The SiloPatrol® SE Model SMU and Flexar® guided wave radar sensors make a direct measurement of the distance between the sensor and the material surface. This equipment does not measure the volume or weight of the material within the vessel. The SiloTrack™ software can perform calculations to display the volume and weight of the material. Volume calculations are based upon the distance measurement and the vessel dimensions entered by the user during set-up. Weight calculations can be based upon the distance measurement, the vessel dimensions and material bulk density. Alternatively, weight calculations can be based upon the distance measurement and a Curve Fit Weight Table described previously.

The distance measurement when material level is in the cone of the silo, is limited by the cable travel being stopped by contact with the material, contact with the empty cone section or the mechanical limit as determined by the length of cable supplied with the Model SMU sensor. SiloTrack™ Server software will provide the user notice of this condition when a distance measurement is made into the cone as determined by the vessel dimensions as entered by the user during setup.

NOTE: The calculated volume and weight values should be considered "estimates". Monitor Technologies LLC accepts no responsibility for the accuracy of the calculated and displayed volume and weight values. The accuracy (not stated or warranted) of the volume/weight calculations are effected by the fluctuation and accuracy of various factors. These factors include, but may not be limited to, actual vessel dimensions, sensor mounting location, angle of repose (negative and positive), material bulk density, material flow properties (ratholes, bridging, etc.), material inlet/discharge locations, and material packing. Please consult the factory to discuss applications where volume/weight is of critical importance.
