• To disable the interrupt output, turn ON SM52 (interrupt code output disable flag). (
• To enable the interrupt output, set 8 bits to the data length at "Communication Detail Settings".

Error code list
In the case of format 2 (GOT-A900 series microcomputer connection (format 2)), the error contents (error code) are
appended to the response message during faulty communication.
The following shows error code, error contents, cause, and measures.
Error code
Sum check error
06
The sum check code created from received data differs
H
from the sum check code in the receive data.
Command error
10
H
An unsupported command was used.
Message length error
11
The upper limit of the data length that can be received by
H
the GOT has been exceeded.
Communication message error
12
EXT was not found within the upper limit of the receive
H
buffer.
Clock data setting error
15
H
The setting value of the clock data has error.
Address error
7A
H
The start address of the read/write device is out of range.
Exceeded number of points error
7B
H
The read/write range exceeded the device range.
Precautions
(1) Batch reading/writing crossing over different devices
When using the batch read (RD) or batch write (WD) 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 GOT-A900 series 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.
