Preparations for prototype

This page contains preparations for prototyping parts of an alarm system.

Frontend testdevice

To make possible tests that

• are predictable
• are available independently of the frontend group
• are available independently of machine operation
• are realistic

a test device (FE project) was implemented that

• runs on the frontend (it is a DeviceAccess device and can be installed on the GuP KP1CG01)
• can be configured at runtime (through properties)
• to expose in its properties
• well defined data.

Until now the device can be configured

• to loop different weather data from start of 2009 to end of 2009
  • 18 such data sets are available (compare spreadsheet & doc)
  • an example is temperature which can be used to simulate a device with jittering values that raise and lower
    
  • another example is visibility distance which can be used to simulate oscillating alarms (using a threshold rule)
    
• to loop a custom sequence of integer data elements
• to choose the speed of cycling

This allows for predictable property data.

To add if required later:

• status bit masks
• random simulation of data
