The variable area is the region of memory used to exchange data with
the E5CN/AN/EN-H through communications.
Operations such as reading the process value and reading/writing
parameters are performed on the variable area.
On the other hand, operation commands do not use the variable area.
Note:
Operation commands do not use the variable area.
When accessing the variable area, the position of a variable in the
variable area is specified with a word identifier, area number, and
address in the area.
An address is appended to each of the variable types. Express
addresses in 2-byte hexadecimal and append them for the specified
access size. Each address is composed of a word identifier, area
number, and address in the area.
