Note on ID and node/line

Each device is inserted in a communication line and each line has an ID number within the line. Of course, devices on different lines can have identical node numbers. To positively identify each device (including from PLC), the ID lets you point at each slave uniquely as it was configured by GF_Net (manually or automatically).A line is a communication channel shared by multiple devices. For a Modbus RTU, each port (COM) is a line; for a Modbus TCP, each IP address is a line.If there are errors on multiple devices on the same line, the errors may be caused by the line status (for example, cable disconnected).Using the cursor keys, go to the list and press Enter to scroll the list with the Up and Down keys. Press Enter again to select an item on the list; press Esc to resume navigating on the page. You can scroll the list using the touch screen and select an item by double-clicking.Selecting an item on the list lets you go to dedicated diagnostics for the device in question. The top section of the panel shows the same information as on the list:Type Communication typeDescr DescriptionNode Modbus nodeId Unique IDDevice nameTwo status LEDS:Act status of last communicationSts presence of at least one communication errorThe middle section is divided into two parts: the top refers to the analysed device and the bottom refers to the line on which the device is positioned.
