
Error code list
In the case of format 5 (Digital Electronics Corporation's memory link method), the details (error code) of the error are
appended to the response message during faulty communication.
The following shows error code, error contents, cause, and measures.

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.
