¡El modular process control is suitable for controlling and regulating cooking, smoking, and air conditioning systems as well as all associated devices such as smoke generators, catalysts, etc. It is available in portrait and landscape format. ¡El device has a 5" color display with 27 colors. ¡El user interface masks can be designed and adapted according to individual requirements. For this purpose it is possible to place texts, process values, background images, and icons wherever the user wishes to do so. A status line shows the last alarm.

In 99 process steps all processes required in the system are defined and only need to be invoked when entering the program. A Plug and Play memory is available as an option. This stores all data contained in the device, thereby allowing easy hardware exchange without data loss. ¡El "Teleservice" software allows configuration settings to be made via modem and the telephone network so that an on-site service assignment is not necessary. A communication interface with Modbus or PROFIBUS-DP allows integration into a network.
