Communications

The Ethernet ports are listed as

TCP/IP 0

and

TCP/IP 1

but are described on the front panel as Ethernet 1 and 2. Each port has an IP address and a subnet mask. The subnet mask defines the network address portion of the whole IP address. Devices on one network address cannot communicate with devices on other networks without a gateway.

Set the Ethernet port IP addresses for both ports on a communication interface to separate networks. For example, the IP addresses covered by the subnet mask should be different. If port 1 and 2 are on the same network, only one port can communicate.

Examples

The address of a device that allows access to other networks. Since both ports must be on different networks, only one of the ports can be on the same network as the gateway, and only this port can use the gateway. The gateway allows the port to communicate with IP addresses outside its own network, for example, across a site local area network (LAN) or even onto the Internet, perhaps to allow remote diagnostics.

Example

A communications interface Ethernet port is connected to network 192.200.11.x.

Trusted

Communication Interface.

Define the four serial ports for baud rate, data bits, parity, stop bits, and line type. The front panel serial port is port 0 and cannot be defined.

The normal pattern uses two bits after each data byte. This pattern is either odd/even parity and one stop bit or no parity and two stop bits.
