PLCs
A PLC node represents a physical programmable logic controller on your network. It holds the connection details that Monitor Points use to read tag data.
Accessing PLC configuration
Section titled “Accessing PLC configuration”Open the Hierarchy Editor via Settings → Line Setup → Hierarchy. Select an existing PLC node, or create a new one by clicking the + button and selecting PLC as the node type.
Fields
Section titled “Fields”A human-readable label for this PLC (e.g., Line 1 AB PLC). Used for display in the hierarchy tree and when assigning a Monitor Point.
Communication Path
Section titled “Communication Path”The network address used to reach the PLC. For Ethernet/IP this is the IP address of the PLC, optionally followed by a slot number:
192.168.1.10192.168.1.10,1,0The ClientService on the edge device uses this path when connecting. The format is IP[,slot[,port]].
Communication Protocol
Section titled “Communication Protocol”The protocol used to communicate with the PLC. Currently the only supported value is Ethernet/IP.
PLC state
Section titled “PLC state”The hierarchy editor shows a status indicator next to each PLC node. The edge client reports ok or error back to the platform depending on whether the last connection attempt succeeded. This is useful for quickly identifying communication issues without opening the node.
