MSX-E7511 – Fieldbus DAQ System – Serial communication

The Ethernet system with protocol interpreter function MSX-E7511 has 4 serial interface ports for RS232, RS422, RS485 or TTY (20 mA Current Loop). It allows to filter the actual user data from the protocol and to transmit only this data or to store it in a database. The acquired data of all interfaces can be calculated onboard with the ARM®9 32-bit processor. Furthermore, the system can send commands to output systems of the MSX-E series and can thus be used as a self-sufficient unit in the harsh industrial environment. It 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 Development Mode allows to customise applications individually. Through synchro connection, several MSX-E systems can be daisy-chained and synchronised with one another in the µs range

  • 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

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.

Flexibility through firmware and software adaptation

Thanks to the flexibility of the MSX-E product range, the MSX-E7511 system can be easily extended via firmware, e. g. to install additional protocols on the serial interfaces.

Fields of application

The MSX-E7511 Ethernet system features 4 serial interfaces. Depending on the version, the interface standards are RS232, RS422, RS485 and TTY (20 mA Current Loop). Any application can be programmed either through a firmware adaptation or using the Development mode.

Data collector

Via the RS485 interface, the Modbus RTU protocol can be used. For example, temperature sensors featuring an integrated Modbus RTU interface can be read and the complete protocol interpretation can be made on the MSX-E7511 system. It is thus possible to filter the actual user data – in this case temperature data – and to transmit only this data or to store it in a database

Onboard calculation

As the system can be programmed, it is possible to effect calculations with the different ports.
Example: Using a radar sensor, the position of an object is to be displayed. The sensors indicate the distance via RS422. Three sensors are used:
• Sensor 1 as a reference to control whether there is an object or not.
• Sensor 2 and 3 for establishing the position of the object.
On the MSX-E7511 system, the interface data is read and interpreted. The position of the object is obtained through calculation of the values of sensor 2 and 3 (e.g. as x/y value). Sensor 1 is used to validate the result. The MSX-E7511 system transmits then only the position data to the Client.

Selft-sufficient unit

Using further systems from the MSX-E product range, the ­MSX-E7511 system can also be used as a self-sufficient unit.
Example: Components are acquired via a scanner (RS232). The MSX-E7511 system reads the barcode and sends the corresponding commands for the processing of the components to a MSX-E1516 Ethernet digital I/O system (handling) and a printer (marking). There is thus no need for an additional PLC or PC.



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-E7511:

  • Change of IP address
  • Display of web interface
  • Firmware update
  • Save/load system configuration
