Configuration
Table 4-2. Modbus communication parameters for 2460 Field Ports
d. (Optional). Communication parameters for Host and Field ports can be configured in
the Advanced Port Configuration window (click the Advanced button):
The Advanced Port Configuration window lets you change from standard Port
Configuration to a non-standard configuration. This may be a useful option if, for
example, the 2460 is connected to a host that requires a lower Baud Rate than the
default setting for the 2460. Non-standard settings may also be required in case the
2460 is located far away from the host since maximum communication speed for
RS232 and RS485 depends on the cable length.
For Field Ports the Reply timeout and Number of retries parameters can be adjusted in
case a connected field device responds slowly to queries from the Rosemount 2460.
The default setting is sufficient in most cases.
For Host Ports the Min response time and Max response time define the time slot in which
a response from the Rosemount 2460 will be sent to a Host system. If needed, you may
change these parameters to match the requirements for a particular host system.
Configure the desired parameters and click the OK button in the Advanced Port
Configuration window to return to the 2460 System Hub Configuration window.
2. In the 2460 System Hub Configuration window click the Next button to continue the
installation procedure of the 2460 System Hub.
