Description
There is no Ethernet communication line setting
corresponding to the specified vision system
No.
The vision system dedicated function is already
being executed for the same vision system.
Trigger is issued before the vision program is
loaded.
Send command character string specified in
(S2) of the MVCOM instruction are outside the
range of 1 to 191 bytes.
The data length received by the MVCOM
exceeds 256 bytes.
Or the storage device space specified in (D) is
insufficient.
The character string length of cell/tag name
specified in (S2) of the MVIN/MVOUT
instruction is outside the range of 1 to 32 bytes.
The cell/tag specified in (S2) of the
MVIN/MVOUT instruction does not exist in the
vision system.
Or the data type of the cell/tag specified in (S2)
of the MVOUT instruction and the transfer data
type/range specified in (S3) do not match.
• Data received by the MVIN instruction cannot
be recognized as numeric data.
• At the BIN conversion mode of the MVCOM
instruction, received data cannot be
recognized as numeric data.
The transferred data specified by the MVOUT
instruction (S3) is incorrect.
Error Processing
The block processing in
execution is stopped and
the next block is executed.
Keep executing Motion

Corrective Action
Correct the program to use the vision
system No. which has the Ethernet
communication line setting.
Correct the program to execute the
following vision system dedicated function
after confirming the status storage device
of the vision system not in "In execution".
Correct the program to issue a trigger after
confirming the status storage device of the
vision program has become "1".
Correct the program to make the length of
the send command character string
specified in (S2) from 1 to 191 bytes.
• Do not use the native mode command
where the data length of the result
exceeds 256 bytes.
• When the data length of the result is
within 256 bytes, correct the device No.
of (D).
• Correct the program to make the length of
the cell/tag name specified in (S2) from 1
to 32 bytes.
• Check that the cell/tag specified in (S2) is
defined in the vision system side.
• Correct the program so that the data type
and data range of (S3) match the vision
system side at MVOUT instruction.
To acquire the data other than numerical
value (string, etc.), specify "0: ASCII" to
(S3) of the MVCOM instruction or correct
the program to use the MC protocol.
When the floating point type is specified in
the data of (S3), correct the program so
that the data is within the range of the 32-
bit floating point type.
