DeviceHub

overview the devicehub module allows you to connect devices to litmus edge, as well as add register values as tags for data polling devicehub can work with devices by most major manufacturers, such as siemens, allen bradley, hitachi, and so on it includes device specific drivers (serial, ethernet, socketcan, and file based) for complete information about the supported devices/drivers, see the industrial systems connection guide docid 8o4ksduafz6jcegj0whs4 devicehub high level architecture the above diagram represents an example of the devicehub feature in litmus edge by offering drivers that form a two way connection with plc hardware devices drivers collect register information from plc devices (and other industrial assets) the specific register of each unique plc is recognized as litmus edge tags register information is stored in tags, and these tags are published as topics to the internal message broker you have the option of saving data in the internal datastore by selecting the enable data store option with a specific retention time once you have added a tag to a connected device, litmus edge polls that tag for data with the frequency you selected the system normalizes the polled data and posts it to the internal message broker you can then subscribe to the data available from the message broker for processing, visualization, and analysis you can access the devicehub module by selecting devicehub from the navigation panel refer to the following resources devices docid 0omx72vihuqpaqmpal7tm add/connect devices to litmus edge manage the connected devices with actions such as edit, refresh, and stop/start optionally, add custom metadata to devices in the form of key/value pairs tags docid\ ckw1ut 55yl7prdysfxjw add tags individually, in bulk, or by browsing a connected device manage tags with actions such as modify, view, and copy asset discovery docid\ ahuec5w2p8 zlogcxhsgp enable/disable the discovery mode when discovery mode is enabled, litmus edge allows you to view devices on the network it is connected to utilities docid\ ijgdjv64iwgalnyxlb2k8 test connectivity of ip addresses and accessibility of specific ports devicehub guides docid\ wxnaso93a33kf0 oxslf2 review how to guides to leverage different functionalities within devicehub devicehub troubleshooting docid\ oy8lh0 pclnoklnm 6jaj
