Configuration
Step 3. Port configuration
1. Verify that the correct modem
(1)
(TRL2, RS485, Enraf, Digital Current Loop (DCL)) is installed, and
communication ports are properly configured. In most cases there is no need to change any
communication parameters. Standard configuration is automatically set for each modem type.
However, the
Advanced button allows you to change communication parameters in case the
standard settings do not match specific requirements.
a. Modem . The Rosemount 2460 supports a large number of modem types. Verify that correct
modem is installed on each port to be used. See Appendix A: Specifications and Reference Data
for details on available modems and protocols.
b. Port Type . The Rosemount 2460 has eight communication ports. They are normally configured
as six Field ports and two Host ports. Host ports can be connected to TankMaster work stations
as well as other hosts.
The Field
ports are connected to Rosemount 2410 Tank Hubs and other supported field devices.
See also “Connecting to a Rosemount 2460 System Hub” on page 30 .
c. Protocol . The Modbus protocol is the standard option in Rosemount Tank Gauging systems.
However, other protocols are supported as well. See Appendix A: Specifications and Reference
Data . For protocols which are not automatically detected by the system hub, you may configure
communication protocol and parameters manually by clicking the Advanced button (see step 2
below).
d. Settings . Verify the communication parameters. Default communication parameters for
Rosemount 2460 Host and Field ports are shown in Table 4-1 and Table 4-2 on page 60 .
