1.9 Computer Link Errors
Details
Communication ends with timeout.
CNC has a 248-byte receive buffer.
The time during which CNC receives
248 bytes exceeds the "TIME-OUT"
value set in the I/O device parameter.
HOST ER (CNC DR) signal is not turned
ON.
Communication ends with parity H.
Communication ends with parity V.
Although CNC transmits DC3 (request to
stop data transfer) to the HOST, it
receives data of 10 bytes or more from
the HOST, thus terminates
communication.
When CNC is transmitting data to the
HOST, it receives data of 10 bytes or
more from the HOST.
1) Set a greater timeout value in the
input/output device parameter.
2) Recheck the HOST software as to
whether or not the HOST transmits
data in response to DC1 from CNC
(data request).
3) Check whether or not start code of
computer link parameter is set to 0.
1) Check whether or not the cable is
disconnected from the connector.
2) Check whether or not the cable is
broken.
3) Check whether or not the HOST power
is turned ON.
1) Recheck the HOST software as to
whether or not the data to be
transmitted to CNC is ISO code.
1) Recheck the data to be transmitted to
CNC.
1) Recheck the software as to whether or
not the HOST stops transmitting data
within 10 bytes after receiving DC3.
2) Recheck the HOST software as to
whether or not the HOST transmits
data such as a command or header to
CNC during receiving a work program.
