Process Messages functions
- Reading data out of the machine controls and storing them in a database
- Graphic and tabular presentation for an easy and fast analysis
- Filtering according to different criteria, for example the duration of an event
- Printing and sending evaluations and logbooks
- Export to Excel
The benefits you derive from Process Messages
- Long-term recording of PLC messages
- Documentation available in graphic and tabular form
- Detailed evaluation and analysis of the data according to different filter criteria to reveal optimisation potential
- Early detection of problems in the production process to prevent the production of reject parts right from the start
Profitable evaluations with Process Messages
Machine controls (PLC) generate a multitude of messages and alarms. Those supply information about frequency and duration of aggregate disturbances and can be called up through the operating panel of the machine control. Because of the limited memory capacity in older machine controls, the messages available there are only retrievable for a limited time and are usually lost when the machine is switched off.
Furthermore, the lack of sensible filter and sorting possibilities prevent effective on-site evaluations at the machine. In addition, background noise in the production environment, also handicaps concentrated work.
Clearly structured presentation of all process messages
The MES module Process Messages reads out the process messages directly from the machine controls via data interfaces (e. g. Siemens S7). The information gathered here is permanently stored in a database. Using an office client, the maintenance technician can now receive information about the current messages of the respective machines right from the PC in his office and react accordingly.
Clearly structured, conveniently operated evaluations display the frequency and duration of occurring messages in graphs or tables within the defined time range and selected machine(s) and plant(s). Information classified by frequency or duration delivers e.g. most important reasons for downtimes etc.
Optimisation strategies can be derived from the analyses of those downtimes in order to minimise future machine failures and to maximise production. You receive graphic and tabular evaluations and filtered according to various criteria. Even micro-stops are visible with this approach.
