Note

After deleting a DeviceHub device, we recommend re-booting the LoopEdge IPC (Industrial PC) before adding another PLC to DeviceHub. It takes some time before the device will actually delete in the back-end.

Manage a Device

If the PLC is not physically connected to the the network as loopedge, user can manage the device driver and stop the calls to the PLC. Devicehub has a manage topic which can be used to start stop the driver instance using flows. 

To Stop a driver communication

Send the string payload shown below to the devicehub.manage.deviceid topic. 

Code Block
{"command": "pause"}

To Start a driver communication

Send the string payload shown below to the devicehub.manage.deviceid topic.
