MSX-E3601 – Fieldbus DAQ System – Vibration measurement

The Ethernet system for noise vibration measurement MSX-E3601 is available in 2 versions: MSX-E3601 with 8 SE/diff. inputs and 8 current sources for ICP®-/IEPE-sensors or MSX-E3601-2 with 2 SE/diff. inputs and 2 current sources for ICP®-/IEPE-sensors. All analog inputs can be acquired simultaneously. The system was developed for the acquisition of dynamic signals in the harsh industrial environment and thus has a robust normed metal housing with the degree of protection IP 65 and an extended temperature range from -40°C to +85°C. The ARM®9 32-bit processor allows the calculation of the acquired values. The Development Mode allows to customise applications individually. Through synchro connection, several MSX-E systems can be cascaed and synchronised with one another in the µs range

Communication interfaces

  • Web server (configuration and monitoring)
  • Command server SOAP for transferring commands
  • Data server (TCP/IP or UDP socket) for sending acquisition data
  • Event server (TCP/IP socket) for sending system events (Diagnostics such as temperature, short-circuits …)
  • Command server Modbus TCP and Modbus (UDP) for sending commands

Synchronisation/time stamp

Time stamp

Several MSX-E systems can be synchronised with one another in the µs range through a synchro connection. This allows to start a synchronous data acquisition, to
generate trigger events and to synchronise the time on several MSX-E systems. Furthermore, the systems have a time stamp that logs the point in time at which the data was acquired by the system.

The combination of synchronisation and time stamp (TS) allows the clear allocation of signals that were captured by several systems.

Acquisition modes

Sequence mode

In sequence mode, a list of channels is acquired. Thereby, the single measurement rows are stored one after another. The client receives the acquired values asynchronously to the acquisition through a socket connection. In the sequence mode, the measurement values are read in chronological order, this means the oldest values are read first. The acquisition can be effected continuously, with or without delay or in combination with a hardware or synchro trigger

Onboard programming / stand-alone operation

Development mode

With the Development mode of the MSX-E systems you can customise your measurement, control and regulation applications to fit your requirements. The programs run directly on the MSX-E systems, which has two advantages: external PCs are relieved and you can process data freely according to your requirements. This helps you to improve the efficiency of your processes and to secure your investments.

Anti-aliasing filter

Low-pass filters are used before or during digitising in order to remove all frequency components which are higher than the Nyquist frequency. This is to make sure that the digitised value or result does not contain any unwanted frequencies (aliasing frequencies). According to the Nyquist criterion, in order to obtain the full signal information, the sampling rate must be at least 2 x the signal band width.

Firmware and software adaptation

Because MSX-E systems are very flexible, the MSX-E3601 firmware can be easily extended. Thus, calculations such as RMS or limit values etc. can be
integrated. Using the Development Mode, it is possible to create self-sufficient intelligent nodes.


The ConfigTools program allows an easy administration of the MSX-E systems. These are automatically detected in the network. ConfigTools
consists of common and specific functions. In addition, with ConfigTools, the complete configuration of a MSX-E system can be saved and transferred to another system of the same type (clone function). ConfigTools is included in the delivery

ConfigTools functions for MSX-E3011:

  • Change of IP address
  • Display of web interface
  • Firmware update
  • Save/load system configuration
  • Save/load channel configuration
  • Monitor for analog inputs
