For example, E1 represents the first Ethernet port, C1 represents COM1, and C2 represents COM2. The ports of an AH10SCM series module are marked with TR1 and TR2, and the ports of an AH10EN series module are marked with X1 and X2. Besides, if the IP address assigned to an Ethernet port is a dynamic IP address, or a port of an AH10SCM series module is not a Modbus port, the Ethernet port or the port of the AH10SCN series module will be gray, and cannot connect to any network.
There are several ways to connect the nodes in the working area to networks. Connecting a port to a network by means of dragging the port The users press the left mouse button while the mouse cursor hovers over a port. A dotted line is under the existing network.
