The following table summarizes setup areas 0 and 1.
Area
Setup area 0 This area groups together the protect, manual control, opera-
tion, and adjustment levels.
Setup area 1 This area groups together the initial setting, communications
setting, advanced function setting, and calibration levels.
The type code depends on the parameter. Refer to 3.1 Variable Area
(Setting Range) List for details.
The variable type is converted to 2-byte ASCII and loaded to the frame.
The following table shows the available variable types.
Variable type
C0/80 R/O (read only) parameter for setup area 0.
C1/81 R/W parameter for setup area 0.
C3/83 R/W parameter for setup area 1.
Note: Setup area 1 has no read-only parameters, so there is no variable
type "C2."
An address is appended to each of the variable types. Express
addresses in 2-byte hexadecimal and append them for the specified
access size. The address depends on the parameter. Refer to 3.1
Variable Area (Setting Range) List for details.
The number of elements is expressed in 2-byte hexadecimal. The range
that can be specified for the number of elements depends on the
