  • Page 7: Introduction

    The System 7000 data acquisition instrument (scanner) may be remotely programmed via an Ethernet (TCP/IP) interface. Any high-speed, modern personal computer supporting this interface may be used to program the System 7000 and, as a result, the scanner can be a part of an automated instrumentation system.

  • Page 8: Definition Of Terms

    The System 7000 is said to be scanning after it has completed an “arm/start” sequence and it is actively acquiring data. A scan in the System 7000 refers to a single group of data that is acquired Scan simultaneously. For example, if you have 2 cards in your scanner (with 8 active channels per card), a single scan consists of all 16 readings made at the same point in time.

    3.3 Establishing a Connection to the Scanner The first step in programming the System 7000 scanner is connecting to one or more of its TCP and UDP ports. TCP Command Port You must connect to the command port in order to send commands to and receive responses from the scanner.

  • Page 18: System Validation

    3.4 System Validation After you have successfully connected with the System 7000 you may wish to confirm the connection by validating that you are, in fact, connected to a System 7000. LabVIEW Use the ID Query parameter to the Initialize VI to automatically perform a check.

    Card-level configuration commands are performed on an individual I/O card. Any settings are applied to all channels on the card. Instructions on how to determine the appropriate values for the settings is beyond the scope of this manual, see the “System 7000 Instruction Manual”, the StrainSmart help system, or contact the Vishay Micro-Measurements application engineering department for assistance.

    (those whose inputs change rapidly). You should always attempt to match your scan rate with the highest rate of change of your inputs. The System 7000 has a base-10 and a base-2 master clock and you are provided with a selection of scan rates for both clocks.

  • Page 22: Recording

    Continuous Time-based Recording To set up the System 7000 scanner for continuous time-based recording perform the following steps. 1. Assign all channels to a single recording group (group A). 2. Configure the time-based recording mode to be “Continuous”.

  • Page 23: Advanced Recording Options

    3.9.2 Advanced Recording Options 3.9.2.1Recording Groups The System 7000 is capable of assigning every channel on a card to one of four recording groups (A-D). This may be used as a means to assign different recording rates and configurations to channels. In other words, even though all channel data is being acquired at the same rate you are capable of storing the data with a variety of different rates and methods.

  • Page 27 Manual Recording “Pre-Record” Buffer Size The System 7000 buffers a defined number of scans. You may specify that when you send the “Start Manual Recording” command to the scanner you would also like to record some number of scans that occurred just previously.
  • Page 28 Figure 5 shows 'trip scans' as yellow dots. Defining Limits In the System 7000 scanner defining limits is a four-step process. First define the limit conditions, next define how you want the card to respond to a limits condition, then assign a limit condition to a channel, and, lastly, configure how you want recording to occur based on that limit.
  • Page 29 Table 6 Number of “Pre-Limit” Scans The System 7000 buffers a defined number of scans. You may specify that when a limit is tripped you would also like to record some number of scans that occurred just previously. You must specify the number of “pre-limit” scans that you would like to have recorded. If you'd like to think of acquiring N number of seconds of "pre-limit"...

    3.14.1 Identifying and Reading the Data File When a card on the System 7000 is configured to record data, the recorded data is stored into a data file on the card’s compact flash. This file has the extension “.7KD”. You must download the file from the card and then decode the data in the file.
  • Page 39 Your application must be able to keep up with reading the TCP packets as they are sent from the System 7000. If during the debug stage, the data port quits transmitting you will likely find it necessary to restart your PC and the System 7000.

  • Page 41: Scan Id

    3.14.2 Decoding the Data File In order to maximize data transfer speed and to minimize disk space requirements, the System 7000 employs a proprietary real-time data compression algorithm on its recorded data. This data structure provides the ability to store data using multiple recording rates. This format also reduces the size of the raw data file by 50% or more.

  • Page 42: Status Information

    Programming note: Though data compression has many advantages, it also means that all raw data files have to be read sequentially. It is impossible to jump to scan number 10,000 without first starting at scan number 1. Vishay Micro-Measurements System 7000 Programmer’s Reference Manual Page 42 of 142...

    This Microsoft Visual Studio C# code snippet shows a basic technique for decoding the data found in a System 7000 data file from a single card.

In this sample, the decoded values are written to a console window.

    3.14.4 What is a Header File? The System 7000 stores a header file (extension “.7KH”) along with the data file. This is a legacy feature that is required by Vishay’s StrainSmart application. You do not have to download or use this file, but is recommended that you delete this file when the corresponding data file is deleted.

    The exception is the command to set the Box Number (ID). 3.15 Acquiring Real-time (Online) Data The System 7000 has the ability to broadcast real-time (online) data via the UDP data port. This data is broadcast while the System 7000 is actively scanning.
  • Page 49 0.00, many applications remove this zero offset from all subsequent readings (both scanned and single-point readings). The zero reading is not stored on the System 7000 scanner, so you must programmatically read and store this value for each channel.
  • Page 50 Typically the channel is also zeroed before calibration. If you have a remote sense circuit attached, you should leave the calibration factor at the default value of 1. Please refer to the “System 7000 Instruction Manual” for more detailed information. The steps in performing a shunt calibration are: 1.
