3.3.2 IN Data Format (Produced Connection)
IN data occupies 8 bits. The status and data are determined by the command and data bit content.
7 6 5 4 3 2 1 0
Status 2 / I/O Address (LSB)
Status 3 / I/O Address (MSB)
Status 7 / Data 3 (MSB) / Error code
Reply bits
00: Indicates a 0 to 7 status (error) at the VS-212DN. Indicates an "end in error" condition during data
reading/writing, and the error code is written to address 7.
01: Indicates an error-free completion of data reading.
10: Indicates an error-free completion of data writing.
11: Indicates an error-free completion of the command simultaneously with data writing.
(1) Status bits
Status bits are enabled when the reply bit (see above) is "00", "10", or "11", and the VS-212DN writes
the following signals to the PLC.
However, when the command bit is "01", "10", or "11", and the reply bit is "00", this indicates that data
reading/writing ended in error, and the error code is written to address 7.

(2) Data reading request (command/data: 01)
When the reply bit is "01", the I/O address (Hex, Word) is enabled at addresses 2 and 3, and the I/O
address data is enabled at addresses 4 to 7.
(3) Data writing request (command/data: 10, 11)
When the reply bit is "10" or "11", an "error-free completion of data writing" status is enabled.
