SCADAPack x70 Driver Guide - Port Function - Terminal Server (Configure a Device Configuration Item)

Port Function - Terminal Server

This allows you to connect to a TCP port on a remote TCP/IP node, such as a terminal server, or another SCADAPack x70 device port that is configured as a Server port.

It can also be used to connect to an application on a host computer, or another SCADAPack x70 device port that is configured as a Client port.

General Setup

Port Mode

Use the combo box to specify the mode in which a port is operating. The options vary, depending on the port and device type, and can comprise a combination of the following:

RS232 (RTS Off)
RS232 (RTS On)
RS232 (RTS) Keyed - this requires you to Configure Serial Multidrop Settings.
RS232
RS485 2 Wire

Baud Rate

Use the combo box to specify the baud rate used for transferring data via the port.

Serial Format

Use the combo box to specify the number of data bits used to transmit each byte of data and the parity. The options comprise:

8-bit No Parity
8-bit Even Parity
8-bit Odd Parity
7-bit Even Parity
7-bit Odd Parity
8-bit No Parity 2 Stop Bits.

Terminal Server Setup

Port Mode

Use this to define whether the port operates as a client or a server for terminal server sessions.

Client

A Client port initiates connection requests to a TCP port on a remote TCP/IP node, such as a terminal server, or another SCADAPack x70 device port that is configured as a Server port.

Server

A Server port listens on the specified TCP port for connection requests from a client, such as an application on a host computer, or another SCADAPack x70 device port that is configured as a Client port. This is the default setting.

TCP Listen Port Number

This setting identifies the TCP port that servers listen on when the Port Mode is set to Server. You can enter a value from 1 to 65535. The default value is 5000#, where # represents the port number. For example, for serial port 1, the default value is 50001.

TCP Port Number

Identifies the TCP port that clients connect to when the Port Mode is set to Client. You can enter a value from 1 to 65535. The default value is 5000#, where # represents the port number. For example, for serial port 1, the default value is 50001.

You can use any port number for the TCP port as long as it does not conflict with another port number in use on the SCADAPack x70 device. For example:

Port 502 is used for connections from Modbus/TCP Clients when the SCADAPack x70 device is operating as a Modbus/TCP Server.
Port 504 is used for SCADAPack x70 logic debugging.
Port 5001 is used for HART pass through for the 6602 HART module.

IP Address

This allows you to define the IP address for the serial port when the Port Mode is set to Client.
