Key Features

  • Vibration Visualization: The EDM Vibration Visualization feature is available in EDM VCS software all test types, including MIMO VCS. This option provides fast and efficient structural model generation and full 3D visualization of the online vibration pattern on the structure under test.
  • Multiple instances of EDM VCS can run simultaneously on the same computer. Each instance connects a Spider system to run the vibration controller software. All instances must run different tests. This feature provides a central place to control multiple Spider systems and perform vibration tests separately.
  • Black Box Mode: Operating Without a PC
    A supported front-end can operate in Black Box mode which allows it to perform a test without a connected PC. In this mode, a PC is used only to configure the system before the test and then to download the data after the test is complete.
  • Multi-shaker control (MSC) is a unique feature offered enables users to view and monitor multiple shaker tests from one PC station. Up to 12 controllers can be accessed simultaneously.
  • Continuous Data Recording
    During vibration control, all measurement input and drive signals can continuously record to a Spider-NAS or the internal storage residing in each front-end. Users can view and analyze data files with Crystal Instruments Post Analyzer. The variable sampling rate can be enabled to simultaneously record slow-change signals together with high speed vibration data.

A Spider system can consist of one or more Spider hardware front-ends. The user constructs the system by combining Spider front-ends detected on the same LAN. The software validates and displays hardware attributes of each Spider front-end. The following hardware is supported by EDM VCS software for vibration control, monitoring, and data acquisition.

  • Spider-81 Premium Vibration Controller
  • Spider-81B Basic Vibration Controller
  • Spider-80X High Channel Vibration Controller – Scale up to 512 Channels
  • Spider-80Xi High Channel Vibration Controller – Compact, handheld high channel system
  • Spider-80M MIMO Vibration Control System
  • Spider-80SG General Data Acquisition Device with Strain Measurement


Monitoring Through EDM Cloud

All tests in EDM-VCS support status checks through EDM Cloud. With EDM Cloud support, users can set up any VCS test to upload live data or run logs for completed tests to a cloud storage space provided by Crystal Instruments, where data is securely stored in the user’s account.

The EDM Cloud website is located at Users can access EDM Cloud from anywhere in the world to check the status of past and current tests. A secure login flow ensures the status can only be checked by authorized personnel with proper credentials. Multiple logins for accessing the same Cloud account is available.
