The Ethernet incremental counter system MSX-E1701 has 4 incremental counter inputs or 8 PWM outputs with status LEDs and 16 digital I/O, 24 V. The digital lines can be parameterised as pairs of inputs or outputs. The system was especially developed for data acquisition and calculation close to the test object in the harsh industrial environment and has  a robust normed metal housing with the degree of protection IP 65. It has 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

Asynchronous acquisition

With the asynchronous acquisition, the digital inputs can be read out via SOAP or Modbus function. For each function call, the values of one channel are transmitted.

Synchronous acquisition

With the synchronous acquisition, the inputs are first initialised and then the acquisition is parameterised. The acquisition runs automatically depending from a trigger source. Either the 24V trigger input or a synchro trigger can be used as trigger source

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.



The MSX-E1516 Ethernet system has a 16-bit watchdog which can be programmed in 3 time units (µs, ms, s). The watchdog is used for automatically resetting the digital outputs to 0 V after a defined time in order e. g. to switch off actuators if an error has occurred.


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
