eBus device memory
KBR eBus devices feature a buffered memory for recording historical information. This memory is configured as a ring buffer, meaning that if the memory is full, the oldest entries are overwritten. You can configure this device memory as either read-only or read and transfer to an SQL database on the computer. The following memories are available for eBus devices:
|Memory type||Device types||Device memory depth|
|Lad profile memory||
|Switching operations memory||
Read device memory and save in SQL database
The function described below can only be configured for either a channel, a device, a bus segment or for an entire location. This way, you can read all device memories in one action if you want to. Automated reading is only supported in visual energy 4 but not in the Starter edition.
Select the 'Database' tab or either the location, segment or device. Then, select the desired memory type. To start reading the data and saving it in the SQL database, click the 'Update' button
