■5. Precautions
(1) Batch reading/writing crossing over different devices
When using the batch read (R) or batch write (W) command, do not batch read/write crossing over the different
devices.
This will cause an error response.
(2) Storage order for 32-bit data
To use the program of Digital Electronics Corporation's memory link method with [32bit Order] setting to GOT1000
series, set [HL Order] to [32bit Order] for [Communication Detail Settings] when 32-bit data is set for GOT-A900
series.
With setting [LH Order], the order of upper bits and lower bits are reversed when the GOT displays and writes 32-bit
data.
