The SmartCheck from Schaeffler is a compact, innovative, modular online measuring system for continuous monitoring of machinery and process parameters on a decentralized basis. It can be used on assemblies where such monitoring was previously too costly.

The SmartCheck is suitable for early detection of rolling bearing damage, imbalances and misalignments on:

• Electric and geared motors
• Vacuum and fluid pumps
• Ventilators and fans
• Gearboxes and compressors
• Spindles and machine tools

The communication with the FAG SmartCheck device has been tested on a device with the following parameters:

...

The protocol for communication with the FAG SmartCheck vibrometer is implemented as a Java server event in D2000.

If the FAG SmartCheck is connected to the local network, by the appropriate IP address it is possible to connect to join it using its IP address. java Java event communicates with the device by using XML Soap (Simple Object Access Protocol) via http requests. Several types of requests can be sent to the device, but the D2000 implementation of FAG SmartCheck protocol uses two types of requests:

• authenticate - user User's login to the device. The Valid username and password are required to execute this request. Only one user can be signed in at one time, so if configuration of the device is to be modified via web interface, communication with D2000 must be stopped.
• liveCharacteristicValue - querying "live" data from the device. These data are collected by device in real-time, such as vibration, temperature, voltage, load, but also the digital rotational speed of the device.

Communication with the FAG SmartCheck is established using the device's IP address , and works as followsof device, by following procedure:

• An authenticate request is sent to device. This request is generated by uses username and password which are used to connect to valid for the device. 
• The device will send sends a response, which will indicate, if whether the login to the device was successful.
• Assuming that the user is successfully logged in to the device, If the login was successful, D2000 sends a liveChararacteristicValue request is sent to the device. This request is also generated by username and password which are used to connect to the device.
• The device sends measured values a response Assuming that the username and password are correct, measured values are sent as a response from device. (vibration, temperature, voltage, load, digital speed).

Communication configurationConfiguration of communication:

The structured variable SV.FAG.SmartCheck.Parameters is used to configure communication.  This structure has to be dimensioned to as many rows as there are devices. The meaning of each column is as follows:

• DeviceName - Device name defined by user (not used in communication).
• IP - Device IP address of the device. Example: http://172.16.1.128
• User - Username to login to the device.
• Password - Password to login to the device.
• Period - The period (in seconds) at which data is read from the device. It is given in seconds.
• Active - The active  If this column is True, communication is represented by this parameter. It can be True or False. This parameter determines whether we want to communication to run or not.active. The False value disables communication (e.g. if it is necessary to access the device's web interface for configuration).

Output from the communication is written to the structured variable Communication output is continuously written to the SV.FAG.SmartCheck.Values structure, which has as many rows, as there are devices. The meaning of each column is as follows:

• Vibration - Device vibrations .(g)
• Temperature - Device temperature .(°C or °F depending on configuration of the device)
• Voltage - Device voltage .(V)
• Load - Device load .(%)
• DigitalInput - Device RPM.rotational speed (rpm)
• Status - State of communication. It can take on the following values:
  • 0 - Connected (communication is ok)
  • 1 - Disconnected
  • Login error - Username or password is incorrect.
  • (communication is stopped)
  • 2 - Connection error - Could not connect to device . Possible causes: The (e.g. the device is not connected to the network, or the machine's IP address is invalid.)
  • 3- Login error - Username or password is incorrect
