Use the following definitions for the transducer block details tables:
#
Name
Description
Msg type
Data type
(size in bytes)
Store
Access
128
Index of the FOUNDATION Fieldbus parameter in the object dictionary
Name of the fieldbus parameter used in the code
Provides a description of the parameter.
VAR
ENUM
METHOD
STR
ARR
REC
The FOUNDATION Fieldbus data type. The size of the data in bytes is in
parenthesis. For example, FLOAT (4) would mean the variable is a float
of size 4 bytes.
The class of memory required, and the update rate in Hz if applicable.
Dynamic
Dynamic/20
Nonvolatile
Static
The type of access allowed for the parameter.
Table A-2: Access
Read only
RW in any mode
RW (OOS)
Micro Motion Model 2700 Transmitters with FOUNDATION Fieldbus
Variable — a variable value
Enumeration — a value from a discrete list
Method — initiates an action within the device
String — a length of ASCII characters (letters, nu-
merals, symbols, and punctuation marks)
Array — data structure that contains an organized
group of elements
Record — a record defined by the FOUNDATION
Fieldbus organization — see section 5.13 of
FF-890-1.3

Cyclic data, parameter updated periodically in 20
Hz
Nonvolatile parameter that must be saved on the
Model 2700 transmitter.
Acyclic data, parameter changed on a deliberate
write
Read only access is allowed for the parameter
Read/write, with the transducer block in any mode
Read/write, with the transducer block in Out of
Service (OOS) mode
