Module description
The gateway receives measured values from the AP (south protocol). The station is responsible for the cyclical renewal of the measured values.
The cycling verification period is configurable (by default 30 seconds). A measured value is detected as not renewed when it has not been received during the cycling period. Following the detection of its non-renewal, it is positioned "questionable" and the "OldData" detail is positioned in the gateway and sent to the centers only once through the north protocols.
When the measured value is cycled again, its new value and its associated quality erase the non-renewal fault. The measured value is then sent with its new values.
It is the reception of the first message for a measured value that triggers the non-renewal monitoring functionality.
Configuration
A number of parameters must be configured in the module. The configuration is transmitted by PowerConf.
Parameters | Description | Default value | Value range |
Cyclic period | Period when cycling is expected. 0=cyclic check is disabled | 30 seconds | [0..3600] |
The module does not need the list of measured values, it only monitors the ones it receives. When a measured value is received for the first time the module triggers the monitoring of its non renewal. Only measured values with a TOC of "cyclic" are monitored.
