Ethernet Slave Connection
A processor has a maximum of 10
Modbus
slaves using an Ethernet connection. A controller with three processor modules supports up to 30 Modbus
slaves using Ethernet ports.Ethernet Port | The Ethernet ports used for Modbus® communications.
Possible value is one of these slices: E1-1 and E1-2, E2-1, and E2-2, or E3-1 and
E3-2. |
Name | Name of the Modbus slave. |
Protocol | When using an Ethernet connection, the controller supports Modbus RTU and TCP; the default value is RTU. |
ID | Ethernet connections require a port. The Slave ID is 255. |
Port | Possible values range from 1 to 65535. For the RTU protocol, the default value is
2000. For the TCP protocol, the default value is 502. Make sure the Port field
matches the port expected by the Modbus master.Modbus slaves having the same Modbus
master must use unique port numbers. |
