Outputs the status codes of PNC-1050 shown in
the table below.
Code
0 Data remaining in buffer.
8 Buffer empty.
16 Data remaining in buffer. PNC-1050
being paused (Pause On being displayed).
24 Buffer empty. PNC-1050 being paused
(Pause On being displayed).
Outputs an error code related to RS-232C interface
(see the table below), and clears the error
simultaneously. At the same time, the error being
displayed is canceled.
Error
code
0 No I/O errors
10 Cause: after execution of an output
command, other output instructions are
sent before the output was not completed.
Action: let the computer to read the PNC-
1050 output by the output instruction
and then send another output instruction.
11 Cause: an error occurs in a device
control instruction.
Action: correct your program.
13 Cause: parameters are overflowing.
Action: correct your program.
14 Cause: the number of the parameters set
is more than specified or a colon ':' was
not used to terminate.
Action: correct your program.
15 Cause: framing error, parity error or over-
run error at the time of data receipt .
Action: match the communication
protocols of both computer and PNC-
1050(baud rate, data bit length, stop bit
length).
16 Cause: the I/O buffer overflows.
Action: This error does not occur when
hardware handshake is performed, but
may occur when software handshake is
performed. If this error occurs, check the
remaining buffer capacity of the PNC-
1050 and send less data than the
remaining buffer capacity.
PNC-1050 outputs the size of the I/O buffer to the
computer when receiving this instruction. It usually
outputs 1024 (bytes).
Aborts both the currently executed device control
instruction and output.
Continues to execute the CAMM-GL III instruction
in operation, aborts other incoming CAMM-GL III
instructions and clears the data buffer.
Initializes all settings established by the device
control instructions. Execution of [ESC].R brings
the same states as the following device control
instructions are executed.
[ESC].J, [ESC].M:, [ESC].N:, [ESC].H:,
[ESC].I: and [ESC].@:
