Windmill Alarm Logger

Whenever Alarm Logger finds a channel that is in alarm, it pops into the foreground of the computer screen and beeps. It can also play an audio file through a sound card, switch on a buzzer or light (for example) and telephone an engineer.

The engineer who was telephoned could use a modem link to dial-up and examine the list of unacknowledged alarms, and view a copy of a logged data file to determine the appropriate action.

You can tell Alarm Logger that you're aware of the alarm and not to report it again until a set time has passed, so acknowledging the alarm. Alarm Logger will record alarms, and the action taken, in a file.

Alarm Logger software also allows delays to be inserted between an alarm being registered and an output being switched - useful in reducing the instances of false alarms. If, say, the temperature of a freezer was to momentarily rise when the freezer lid was opened; the alarm would not activate unless the temperature remained over the limit for a certain time.

It is easy to run Alarm Logger over an Ethernet network, as it actually consists of three programs: a Setup, a Monitor and a Viewer. The Alarm Setup configures the system, letting you set such things as the time between alarm checks or an advisory message to be displayed when a specific alarm occurs. The Alarm Monitor watches the hardware for alarms. When the Monitor flags an alarm, the Alarm Viewer tells engineers about it.

Note: Alarm Logger is an add on to Windmill and will not work without it. Windmill comprises logging, charting, display and control software, and comes free when you buy any of our USB data acquisition units. Alternatively you can buy Windmill with a serial (COMIML for RS232, RS485, RS422 and Modbus devices) or DDE (Harvester) driver.
