The invention relates to a method for remotely diagnosing process conditions in systems such as tablet presses, using computer software. The aim of the invention is to develop a method, which overcomes the disadvantages of methods in prior art and ensures that no modifications, which lead to unintentional effects on the systems, can be made to the software. To achieve this, a programmable control system (PCS) and/or a computer, such as a personal computer (PC), is/are connected to an Internet server, such as a browser, in such a way that--the process image of all conditions and the entire parameterisation of the system (actual condition) is stored on the Internet on a protected home page and/or--the PCS and/or the PC is operated as a subscriber of an e-mail system and issues protected status messages via said system--and the installation and parameterisation of the components and the software are stored either in e-mail form or as a protected Internet page.
