PLC Errors for GE SNPX Protocol (Minor-Major) (cont’d)
Panel Error Code
P499 Hex Value
Description
0x080C
Unable to read or write master device memory locations specified in COMMREQ. Usually caused by invalid
memory address for this PLC. SNP message exchange may have taken place.
0x080E
Modem responded with NO DIALTONE. Modem is unable to complete the requested connection. Check the
modem connections and the telephone line.
0x080F
Service Request Processor response exceeds 1000 bytes;
the SNP-X slave device cannot return the data in an X-Response message.
(This error applies to CMM module only.)
0x090C
Master device memory data length exceeds maximum data size of CMM module (2048 bytes). Must use a
smaller data length. Use multiple COMMREQs if total data length exceeds this maximum value.
0x090E
Modem responded with ERROR. Modem is unable to complete the requested command. Check the modem
command string and modem.
0x0A0C
Slave device memory type is missing or not valid.
0x0A0E
Modem responded with RING, indicating that the modem is being called by another modem. Modem is
unable to complete the requested command. Retry the modem command at a later time.
0x0B0C
Slave device memory address is missing or zero.
0x0B0E
An unknown response was received from the modem. Modem is unable to complete the requested
command. Check the modem command string and modem. The modem response is expected to be either
CONNECT or OK.
0x0C0C
COMMREQ Data Block Length is too small.
(When expected COMMREQ length is 6 words or less. An improper length may cause other minor error
codes 6-11.)
0x0D0C
Invalid Diagnostic Status Word (DSW) starting word or length.
0x0E0C
Invalid maximum SNP message data size.
Must be an even value from 42 to 2048.
0x0F0C
Invalid Privilege Level. Must be 0 through 4 or -1.
0x100C
Invalid Fault Table selector.
Must be 1 for I/O Fault Table, or 2 for PLC Fault Table.
0x100F
Unexpected Service Request Processor error.
(This error applies to CMM module only; the unexpected SRP error code is saved in the Diagnostic Status
Words in the CMM module.)
0x110C
Invalid Fault Table starting index.
Must be 1-32 for I/O Fault Table, or 1-16 for PLC.
0x120C
Invalid fault count. Must be 1-32 for I/O Fault Table, or 1-16 for PLC Fault Table.
0x130C
Invalid Set PLC Date/Time mode. Must be 1-4.
0x140C
Invalid Set PLC Date/Time date, time, or day-of-week value.
0x150C
Unable to retrieve master device PLC time/date from PLC CPU.
0x150F
Requested service is not permitted in a Broadcast request. The master must direct the X-Request message
to a specific SNP-X slave device.
0x160C
Invalid slave PLC type.
Must be 0 for Series 90-70, or 1 for Series 90-30 or Series 90-20.
0x170C
Invalid datagram type.
Must be 01h for normal datagram, or 81h (129) for permanent datagram.
0x180C
Missing or too many datagram point formats. Must be 1-32.
0x190C
Invalid datagram point format data.
