Panel Error Code
P499 Hex Value
Unable to read or write master device memory locations specified in COMMREQ. Usually caused by invalid
0x080C
memory address for this PLC. SNP message exchange may have taken place.
Modem responded with NO DIALTONE. Modem is unable to complete the requested connection. Check the
0x080E
modem connections and the telephone line.
Service Request Processor response exceeds 1000 bytes;
0x080F the SNP-X slave device cannot return the data in an X-Response message.
(This error applies to CMM module only.)
Master device memory data length exceeds maximum data size of CMM module (2048 bytes). Must use a
0x090C
smaller data length. Use multiple COMMREQs if total data length exceeds this maximum value.
Modem responded with ERROR. Modem is unable to complete the requested command. Check the modem
0x090E
command string and modem.
0x0A0C Slave device memory type is missing or not valid.
Modem responded with RING, indicating that the modem is being called by another modem. Modem is
0x0A0E
unable to complete the requested command. Retry the modem command at a later time.
0x0B0C Slave device memory address is missing or zero.
An unknown response was received from the modem. Modem is unable to complete the requested
0x0B0E command. Check the modem command string and modem. The modem response is expected to be either
CONNECT or OK.
COMMREQ Data Block Length is too small.
0x0C0C (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.
Invalid maximum SNP message data size.
0x0E0C
Must be an even value from 42 to 2048.
0x0F0C Invalid Privilege Level. Must be 0 through 4 or -1.
Invalid Fault Table selector.
0x100C
Must be 1 for I/O Fault Table, or 2 for PLC Fault Table.
Unexpected Service Request Processor error.
0x100F (This error applies to CMM module only; the unexpected SRP error code is saved in the Diagnostic Status
Words in the CMM module.)
Invalid Fault Table starting index.
0x110C
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.
Requested service is not permitted in a Broadcast request. The master must direct the X-Request message
0x150F
to a specific SNP-X slave device.
Invalid slave PLC type.
0x160C
Must be 0 for Series 90-70, or 1 for Series 90-30 or Series 90-20.
Invalid datagram type.
0x170C
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.
