In the computer link connection, the bit specification writing
of the word device to the ER29-0 (block 29 of the extension
file register) or later of A3ACPU, A3UCPU, or A4UCPU is
not available.
When the bit specification writing of the word device is
required, use the range of block No. 0 to 28.
*2
In the computer link connection, writing to the index register
(e.g., the touch switch function, numerical input function) is
not available.
*3
Only the intelligent function module on the station connected
to GOT can be specified.
Set within the address range of the buffer memory existing in
the target intelligent function module.
*4
The device No. must be set in multiples of 16.
*5
If the special internal relay (M) is converted to the word
device, treat 9000 of the device No. as 0 and set in multiples
of 16.
Example: M9000, M9016, M9240

In the computer link connection, writing to the index register
(e.g., the touch switch function, numerical input function) is
not available.
With the computer link connection, the GOT cannot read/
write data from/to the accumulator.
This is not supported by GT10.
The device No. must be set in multiples of 16.
If the special internal relay (M) is converted to the word
device, treat 9000 of the device No. as 0 and set in multiples
of 16.
Example: M9000, M9016, M9240
