According to manufacturer Jumo, the current system version 4.0 of the scalable mTRON T measurement, control and automation system offers a range of user-friendly improvements. For example, the memory of the central unit has been expanded to 128 Mbytes at no extra cost. In addition, thyristor power controllers from the 'TYA 200' series can now be connected via a system bus. Integration of the supplier's 'Digiline' system - an intelligent sensor network for liquid analysis - is also possible via Modbus. Depending on the bus topology and power supply, up to 62 sensors can be connected to the measurement, control and automation system. By extending the external text variables, up to 90 external batch texts can be transferred. Other features include improvements to the process image editor and the option of remote maintenance of Codesys via TCP.
