Conventions Used in the Menu Pages
To better understand the menu pages that follow
review the naming conventions used. When encoun-
tered throughout this document, the word "default"
implies as shipped from the factory. Each page (Op-
erations, Setup, Profile and Factory) and their associ-
ated menus have identical headers defined below:
Header Name
Definition
Display
Visually displayed infor-
mation from the control.
Parameter Name
Describes the function of
the given parameter.
Range
Defines options available
for this prompt, i.e., min/
max values (numerical),
yes/no, etc... (further ex-
planation below).
Default
Values as delivered from
the factory.
Modbus Relative Ad-
dress
Identifies unique address-
es when using either the
Modbus RTU or Modbus
TCP protocols (further ex-
planation below).
CIP (Common Indus-
trial Protocol)
Identifies unique param-
eters using either the
DeviceNet or EtherNet/IP
protocol (further explana-
tion below).
Header Name
Definition
Profibus Index
Identifies unique param-
eters using Profibus DP
protocol (further explana-
tion below).
Parameter ID
Identifies unique param-
eters used with other soft-
ware such as, LabVIEW.
RUI/GTW Modbus
Identifies unique relative
Modbus (RTU or TCP) ad-
dresses when using the
Remote User Interface /
Gateway.

Range
Within this column notice that on occasion there will
be numbers found within parenthesis. This number
represents the enumerated value for that particular
selection. Range selections can be made simply by
writing the enumerated value of choice using any of
the available communications protocols. As an ex-
ample, turn to the Setup Page and look at the Analog
Input
[`Ai]
menu and then the Sensor Type
[Sen]
prompt (instance 1). To turn the sensor off using
Modbus simply write the value of 62 (off) to register
400043 (Map 1) or register 400369 (Map 2) and send
