Instruction Format Parameter Range ([ ] is default) Explanation
ESC .E [ESC].E None Outputs an error code related to RS-232C interface
Output RS-232C (see the table below), and clears the error simulta-
Error Code 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
size 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,
Set Each Buffer Size <P3> ;<P4>;<P5>;<P6>: buffer polygon buffer and downloadable character buffer
P2: The size of the polygon [6144 (byte)] by defining the parameters.
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
P4: Ignored exceeds 40960, the allocation of the 40 KB data
P5: Ignored 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
code
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
Buffer type Min. Max. Default
