Modbus

Path: Administration > Network > Modbus > serial (or TCP)

Enable or disable access to the Modbus serial or TCP interface by selecting or clearing the Enable check

box.

Set the connection parameters for the Modbus connection - a port number for the TCP connection, or the

parameters for the serial connection. The default serial connection settings are 19200 baud, 1 start bit, 8

data bits, even parity, and 1 stop bit.

Note: If you select None, the Modbus master should be set to use 2 stop bits. For Even or

Odd, use 1 stop bit.

Set the unique ID for the device by providing a value in the Target Unique ID field. The value must be

between 1 and 247 (inclusive).

When you are finished making your selections, click Apply to save your changes.

access

control

You can configure up to four access control entries to specify which NMSs have access to this device.

The opening page for access control, by default, assigns one entry to each of the four user profiles, but

you can edit these settings to apply more than one entry to any user profile to grant access by several

specific IP addresses, host names, or IP address masks.

• If you leave the default access control entry unchanged for a user profile, all NMSs that use that profile

have access to this device.

• If you configure multiple access entries for one user profile, the limit of four entries requires that one or

more of the other user profiles must have no access control entry. If no access control entry is listed for

a user profile, no NMS that uses that profile has any access to this device.

To edit the access control settings for a user profile, click its user name.

Access: Mark the Enable check box to activate the access control specified by the parameters in this

access control entry.

User Name: From the drop-down list, select the user profile to which this access control entry will apply.

The choices available are the four user names that you configure through the user profiles option on the

left navigation menu.

NMS IP/Host Name: The IP address, IP address mask, or host name that controls access by the NMS. A

host name or a specific IP address (such as 149.225.12.1) allows access only by the NMS at that location.

An IP address mask that contain 255 restricts access as follows:

• 149.225.12.255: Access only by an NMS on the 149.225.12 segment.

• 149.225.255.255: Access only by an NMS on the 149.225 segment.

• 149.255.255.255: Access only by an NMS on the 149 segment.

• 0.0.0.0 (the default setting) which can also be expressed as 255.255.255.255: Access by any NMS on

any segment.
