■ List of Services

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 variable type is converted to 2-byte ASCII and loaded to the frame.
The following table shows the available variable types.
Variable type
C0 Double-word data. R/O (read only) parameter for setup
area 0.
C1 Double-word data. R/W parameter for setup area 0.
C3 Double-word data. R/W parameter for setup area 1.
* 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 number of elements is expressed in 2-byte hexadecimal. Specify
the number of elements within the range "0 to 2."
For example, when the number of elements is "0002," this specifies two
items of data from the address.
