Port properties for a Honeywell Universal Modbus channel

The Port tab defines the communication-related properties for a channel The communications port used by the server to connect to a controller. Channels are one slot, point, or screw terminal of an I/O device for a single I/O value, and are defined using the Quick Builder tool.. The Port Type for Universal Modbus can be:

Serial. A serial communications interface, such as RS-485.
TerminalServer. A communications link that enables controllers with a serial interface to be connected to a LAN.
LANVendor. A communications interface using TCP/IP Transmission control protocol/internet protocol. A standard network protocol. to controllers connected to a LAN.

Serial port properties

ATTENTION: The Serial Port settings must match the settings on your communication devices.

Property	Description
Serial Port Name	The device name of the serial port.
Baud rate	The number of data bits per second. The default is 9600.
Number of Data Bits	The number of data bits used for transmission. The default is 8.
Stop Bits	The number of stop bits used for transmission The default is 1.
Parity	Defines parity verification of each character and must match configuration on the end device. The default is NONE.
Checksum	The type of checksum error detection used for the port. Not applicable for this channel. Select NONE.
XON/XOFF	The type of XON/XOFF software flow control used to stop a receiver from being overrun with messages from a sender. The types are: Input (use XON/XOFF to control the flow of data on the receive line) None (default) Output (use XON/XOFF to control the flow of data on the transmit line)
Handshaking Options	RS-232 RS-422 No handshaking options are available for RS-422. RS-485

Terminal Server port properties

Property	Description
Terminal Server A terminal server allows you to connect several controllers and Stations to a LAN even though they only have serial or parallel ports. Most terminal servers also provide a range of serial connection options, such as RS-232, RS-422, and RS-485. See also: controller, LAN, Station. TCP Transmission Control Protocol. Host Name Terminal Server The computer on which the Experion database software and server utilities run. See also: Experion server TPS. TCP Port No	The name and port number of terminal server to which the channel is connected. You can specify either a TCP host name or an IP address, but it must match the TCP host name used when you installed and internally configured the terminal server.
Idle Timeout	The time, in seconds, the channel waits for a successful connection to the server before closing the connection. A value of 0 indicates that the connection is never closed.
Checksum	The type of checksum error detection used for the port. Not applicable for this channel. Select NONE.

Terminal Server A terminal server allows you to connect several controllers and Stations to a LAN even though they only have serial or parallel ports. Most terminal servers also provide a range of serial connection options, such as RS-232, RS-422, and RS-485. See also: controller, LAN, Station. TCP Transmission Control Protocol. Host Name

Terminal Server The computer on which the Experion database software and server utilities run. See also: Experion server TPS. TCP Port No

The name and port number of terminal server to which the channel is connected.

You can specify either a TCP host name or an IP address, but it must match the TCP host name used when you installed and internally configured the terminal server.

Idle Timeout

The time, in seconds, the channel waits for a successful connection to the server before closing the connection.

A value of 0 indicates that the connection is never closed.

Checksum

The type of checksum error detection used for the port.

Not applicable for this channel. Select NONE.
