Error
Possible cause
code
and action
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-
900 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.
12
Cause: incorrect parameter are set to a
device control instruction (the default
value is set to the erroneous parameter)
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-
900 (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-
900 and send less data than the
remaining buffer capacity.
