ESC .E
[ESC].E
None
Outputs an error code related to RS-232C interface
Output RS-232C

neously. At the same time, the error being displayed
is canceled.
ESC .L
[ESC].L
None
Outputs the current logic size of the I/O buffer
Output I/O buffer
Note that the output is done only when the I/O

buffer is empty.
ESC .T
[ESC].T<P1>;<P2>;
P1: The size of the physical I/O [1024 (byte)]
Allocates the 40 KB data buffer to the I/O buffer,

A [ESC].T instruction without parameters allocates
P3: The size of the download- [6144 (byte)]
each buffer size to the default value, and then clears
able character buffer
data in the buffers. If the sum of the four parameters

exceeds 40960, the allocation of the 40 KB data

buffer is readjusted.
P6: Ignore
The maximum vale, minimum value and default
value of each buffer are shown in the table below. If
specifying a value more than the maximum, the
maximum value is set. If specifying a value other
than 0 and less than the minimum, the minimum
value is set. If 0 is specified, 2 is set to the I/O
buffer, 4 to the polygon buffer, and 0 to the down-
loadable character buffer.
ESC .S
[ESC].Sn:
n : Buffer type
0—6 [0]
Outputs the currently set capacity of a User-
Output Each Buffer
definable buffer. The each buffer capacity
Size
corresponding to the parameters 0 to 6 are as
follows.
0: Whole data buffer capacity
1: Physical I/O buffer capacity
2: Polygon buffer capacity
3: Downloadable character capacity
4, 5: Outputs 0 always
Error
Meaning
c o d e
0
No I/O errors
10
During an output instruction being executed,
another output instruction is sent (only the
current instruction is effective)
11
An error occurs in a device control instruction.
12
Incorrect parameters are set to a device control
instruction (the default value is set to the erro-
neous parameter)
13
Parameters are overflowing
14
The number of the parameters set is more than
specified or a colon ':' was not used to terminate
15
Framing error, parity error or over-run error at
the time of data receipt
16
The I/O buffer overflows (In this case, the
PNC-1910 cannot cut properly.)
17
Baudrate is set incorrectly
18
Other I/O errors occur
