Abstract [sv]

This thesis covers the construction of a combined alarm- and logging-system in co-operation with Unneforssågen. Two operator terminals, two micro-PLCs (Programmable Logic Controller) and a main PLC are connected. Sensors are connected to the PLC. The task of the two micro-PLCs is to log the flow of water passing in and out of the system. They also collect and pass on the alarms that are incoming to the main PLC, whose task is to register triggered alarms and send sms. The micro-PLCs are connected to an E300 operator terminal that sends e-mail with logged values of the flow once every twenty-four hours to the person in charge of the environment at the company. The main-PLC is connected to an E600, in which alarms can be seen and acknowledged. At the same time that an alarm goes off, an sms is sent to the person on duty. A number of sensors are brought up and discussed regarding their suitability to the criteria of the company. Also a short discussion about the intelligence in the alarm system is included.
