The following table summarizes setup areas 0 and 1.
The variable type is converted to 2-byte ASCII and loaded to the frame.
The following table shows the available variable types.
* Setup area 1 has no read-only parameters, so there is no variable
type “C2.”
■ Addresses An address is appended to each of the variable types. Express
addresses in 2-byte hexadecimal and append them for the specified
access size.
■ Number of Elements
The number of elements is expressed in 2-byte hexadecimal. Specify
the number of elements within the range “0 to 2.”
