Setting Up Communications
This procedure provides for the selection of the specific instrument on which diagnostic data
is required, and defines the required communication parameters. Perform the setup
procedure using the step-by-step instructions in the next Table.

Step
Procedure
Comments
1
On the Instrument Status display, Figure 3.3 or
3.4, click on Setup. The communication setup
menu, Figure 3.5, appears.
2
Select the Communications Type field and scroll
to select either Link (ICN) or Extended Modbus or
Modbus.
Communications module and wiring
connections must be compatible with
this selection.
3
If link communication was selected, proceed as
follows:
•
Select the ICN Number field and enter the
applicable ICN number: 0 - 7 for standard
link (depends on board position) or 0-1 for a
Mini-link (depends on labeled connection
port).
•
Select the Instrument Number field and
enter the number (0-15) of the target
instrument.
The ICN and Instrument Number fields
are not used if Modbus was selected in
Step 2.
If an ICN communications module is
used, the target instrument number is
determined by the setting of the
address switch on the module. This
switch is read only at power up; cycle
the power if the setting is changed.
If the MOD 30ML built-in ICN
communications circuit is used, the
communications jumper must be set on
the ICN position, and the target
instrument number is determined by
configuring the ICN address and
enabling the ICN on the front panel
device setup display.
4
If Modbus communication was selected, select
the Modbus Address field and enter the address
(1 - 247) of the target instrument.
If a Modbus Communication module is
used, the address of the target
instrument is determined by the settings
of the two address switches on the
module. These switches are read only
at power up; cycle the power if the
settings are changed.
If the MOD 30ML built-in Modbus
communications circuit is used, the
communications jumper must be set on
the RS-232 or RS-485 position, and the
target instrument number is determined
by configuring the Modbus address and
enabling Modbus communication on the
front panel device setup display. Default
is 247.
5
Select the Serial Port field and scroll to select your
computer communication port (Com 1 - Com 4)
