PLC Errors for GE SNPX Protocol (Minor-Major) (cont’d)
Panel Error Code
P499 Hex Value
Description
0x410C
A framing or overrun error has occurred on an X-Attach Response message when establishing a new SNP-
X communication session.
Communications have not been established.
0x410D
SNP slave on CMM module requires PLC CPU privilege level 2 to operate. The SNP slave has rejected a
request to change to a higher or lower privilege level.
0x410F
An SNP-X request was aborted prior to completion due to reception of a Break.
0x420C
A BCC (Block Check Code) error has occurred on an X-Attach Response message when establishing a new
SNP-X communication session.
Communications have not been established.
0x420D
SNP Request or Response message exceeds maximum data length of the CMM module. (Total data length
for Mailbox and all following Buffer messages is 2048 bytes.) The master must use a smaller data length.
Use multiple requests if total data length exceeds the maximum value.
0x420F
An X-Buffer message was received containing greater than 1000 bytes of data. The data is ignored.
0x430C
An invalid message type was received when an X-Attach Response was required when establishing a new
SNP-X communication session.
Communications have not been established.
0x430D
Improper Write Datagram message format. Series 90-70 slave devices use a different format for this
message than Series 90-30 or Series 90-20 slave devices. The master must use the proper message
format for this SNP slave device. (The SNP master in the CMMmodule sends this message as part of the
Establish Datagram COMMREQ command. The datagram has been partially established, but is not usable;
the datagram should be cancelled by using the Datagram ID returned by the COMMREQ.)
0x430F
The SNP-X slave did not receive a response from the Service Request Processor in the PLC CPU.
0x440C
An invalid next message type value was detected in an X-Attach Response message when establishing a
new SNP-X communication session.
Communications have not been established.
0x440D
A datagram error occurred in a Series 90-70 slave device (dual-port error).
0x440F
PLC backplane communications error.
0x450C
An invalid response code was detected in an X-Attach Response message when establishing a new SNP-X
communication session.
Communications have not been established.
0x460C
An expected X-Attach Response message was not received within the response timeout interval when
establishing a new SNP-X communication session. The master has retried the X-Attach message twice
without receiving a response.
Communications have not been established.
0x500C
A parity error has occurred on an X-Attach Response message when re-establishing an existing SNP-X
communication session.
Communications have not been established.
0x500F
A parity error has occurred in a received X-Attach message.
0x510C
A framing or overrun error has occurred on an X-Attach Response message when re-establishing an
existing SNP-X communication session.
Communications have not been established.
0x510F
A framing or overrun error has occurred in a received X-Attach message.
0x520C
A BCC (Block Check Code) error has occurred on an X-Attach Response message when re-establishing an
existing SNP-X communication session.
Communications have not been established.
0x520F
A BCC (Block Check Code) error has occurred in a received X-Attach message.
