review the following information to learn more about the system architecture and network architecture of litmus edge system architecture the diagram below shows the system architecture of litmus edge and the different paths that data can travel through litmus edge details \[1] you have the option of accessing litmus edge through the web ui, the terminal user interface (tui), or rest api see the following to learn more access the litmus edge web ui docid\ y hkza2pmc4iruk ebouk access the terminal user interface docid\ gsdvwb7qwhdhuqf7fkahc overview docid\ knxgkk csgypyphe1de7l \[2] to get data into litmus edge, you will need to configure a connection between plcs and devicehub drivers review the list of available drivers and the parameters that need to be configured in the industrial systems connection guide docid 8o4ksduafz6jcegj0whs4 once the data flows into devicehub, it is sent to the message broker for further processing \[3] once the data reaches the message broker, there are different paths the data can flow you can store the data in a database learn more about database options for litmus edge in datahub docid\ fy5yzjz6ooqc2tu83p3xl there are different options for the data to flow northbound for further processing \[4] you can send the data northbound to the following you can send the data through an application in litmus edge learn more about applications docid\ yabkqsucfr461 ewjgrxf and applications guides docid\ c3zfkllmdu0kttofbyx90 create flows in the flows manager docid bvxnzlgo8fsoglib4o l process the data in analytics docid\ zaowl1npjlkefhjbxhgvu integrate litmus edge with other applications for cloud and db connectivity learn more about integration docid\ sl1ujrrgcnefpgtkdlyra and integration guides docid\ novkmu18kezvhswjtbnpc configure an opc ua server docid\ wqkl83kaiecnh5ish lg2 network architecture the diagram below shows the typical network architecture for litmus edge refer to the callouts in the diagram and descriptions below to learn more options for setting up litmus edge you have the following options for setting up litmus edge on your site learn more about installation and deployments docid 8plvtu3flqlslk10khshb action details option 1 refer to callout \[1] in the diagram litmus edge in a dmz is connected to plcs through a level 2 switch only the "head" plc has a network connection in a designated vlan the litmus edge in the dmz must have access to the same vlan as the "head" plc the litmus edge in the dmz can read from registers of the "head" plc other plcs attached to the "head" plc must transfer their data to the "head" plc to be read option 2 refer to callout \[2] in the diagram litmus edge in a dmz is connected to plcs through a level 2 switch all plcs have a network connection in a designated vlan the litmus edge in the dmz must have access to the same vlan as the plcs the litmus edge in the dmz will be able to connect to all plcs to read data option 3 refer to callout \[3] in the diagram litmus edge in a dmz is connected to other data sources through a level 2 switch all data sources have a network connection in a designated vlan the litmus edge in the dmz must have access to the same vlan as the data sources the litmus edge in the dmz will be able to connect to all data sources to read data option 4 refer to callout \[4] in the diagram litmus edge in a dmz is connected to a plc through a panel switch the panel switch is connected to a level 2 switch the plc is connected to the panel switch the litmus edge in the dmz must have access to the same vlan as the plc the litmus edge in the dmz will read data from any plc connected to the panel switch option 5 refer to callout \[5] in the diagram an rs232 to ethernet converter connects to a plc through an rs232/484 physical connection litmus edge can read from the registers on the connected plc the litmus edge in the dmz will read the data from the plc through the ethernet converter option 6 refer to callout \[6] in the diagram litmus edge in a dmz connects to a remote i/o module/sensor gateway the remote i/o module/sensor gateway is connected to the plc (or in some cases to the level 2 switch) sensors are connected to the gateway through wireless or proprietary technology the litmus edge reads sensor data through the plc or through the gateway if it's connected to the level 2 switch cloud and litmus edge manager setup refer to the following options for setting up cloud storage and litmus edge manager litmus edge manager refer to callout \[7] in the diagram data collected from litmus edge is sent to litmus edge manager for consolidation cloud storage refer to callout \[8] in the diagram litmus edge manager sends data to cloud systems or other enterprise systems learn more about applications docid\ yabkqsucfr461 ewjgrxf and applications guides docid\ c3zfkllmdu0kttofbyx90 integrations refer to callout \[9] in the diagram litmus edge can also send data directly to cloud systems/other enterprise systems through integrations learn more about integration docid\ sl1ujrrgcnefpgtkdlyra and integration guides docid\ novkmu18kezvhswjtbnpc
