The NEMS is a new value/first value and process indicator system consisting of individual NEMS16 devices, each with 16 indicator inputs. By networking via a LAMTEC system bus, it is possible to create an indicator system with a maximum of 1024 signals (64 individual devices). Each indicator input (DC18-30V) can be converted to fault or process status signal as well as normal open or closed contacts and is displayed by means of a luminous, three-colour LED on the front panel.
When an indicator input is switched to the active state, the relevant LED changes over to a flashing light or a continuous light.
It is also possible to print out the signals in chronological order via a serial logging printer or a display and operating terminal connected at the LAMTEC SYSTEM BUS.
The device contains a real-time clock, which is synchronised with another NEMS16 in the system.
Applications
- Process monitoring
- Monitoring of safety interlock chains in combustion engineering
- Chronological recording and processing of fault values and operating data
- Coupling to standard field bus systems (e.g. Profibus) is possible as an option
- Logging and further processing in conjunction with higher-level computer systems
- Decentralised recording of locally distributed signals
