6.4 Variable areas
The area used for data exchange when communicating with the E5AR/ER is called the "variable area".
The PV is read and various setting data are read and written using the variable area of the E5AR/ER.
Operation commands and reading of machine attributes do not use the variable area.
A variable area is accessed by specifying the position of a variable
within the variable area using the variable type and address.
● Variable types Variable types in variable areas are as follows:
● Addresses
(Communication/
CompoWay/F)
Each variable type has an address. Addresses are 2 bytes long and
written in hexadecimal. Addresses are assigned according to units of
access size. Each address consists of a "channel identifier" and an "in-
area address".
