FX Series Positioning Controllers
7.2.2

Assignment of buffer memories

Buffer memories, diversified devices and parameters in the positioning unit are assigned as
shown in the table below, and same data is stored in each pair of buffer memory and devices/
parameters.
For the details of special auxiliary relays, special data registers and parameters, refer to Sec-
tion 6.
In the FX -10GM, buffer memories corresponding to unsupported devices such as special
2N
auxiliary relays, special data registers and parameters for the Y axis are not used.
