for given top and bottom limits
An independent designed alarm administration (self-maintaining;
self-erasing etc.) for each channel
Free configurable printout of the alarm events via a directly
connected printer
Visualisation on a graphical LCD display
Configuration of the whole system via an optional connected PC
Solution
Development of a specific serial bus system for sensor
connection by our partner company TIGRIS Elektronik GmbH. Interrupt-driven
micro controller programming of an 8051 derivate in C. Menu controlled
LCD display with five buttons and two key switches. Optional connection of a PC via RS232.
