Modbus address

Note: The Modbus address is applicable only when you are connecting to the service port from a tool
that uses Modbus protocol. After initial startup, service port connections are typically used only for
troubleshooting or for specific procedures such as temperature calibration. ProLink II is typically
used for service port connections, and by default ProLink II will use the standard service port address
rather than the configured Modbus address. See Section 4.4
for more information.

The set of valid Modbus addresses depends on whether or not support for Modbus ASCII is enabled
or disabled (see Section 8.10.5). Valid Modbus addresses are as follows:

Modbus ASCII enabled:

1–15

,

32–47

,

64–79

,

96–110

Modbus ASCII disabled:

0–127

To configure the Modbus address:

Using ProLink II, see Figure B-2.

Using the display menus, see Figure B-6.

Modbus ASCII support

When support for Modbus ASCII is enabled, the service port can accept connection requests that use
either Modbus ASCII or Modbus RTU. When support for Modbus ASCII is disabled, the service port
cannot accept connection requests that use Modbus ASCII. Only Modbus RTU connections are
accepted.
