GE SNPX Protocol – PLC Error Code Tables
A
The following table lists the errors that can be generated by the GE 90-30, 90-70 and VersaMax
PLC when using the SNPX protocol.
Note: The following errors can be generated from the designated PLC, are monitored by the C-more Micro-
Graphic panel, and displayed on the panel's screen as a hexadecimal value in panel error code P499, if active.
Please refer to the PLC users manual for additional information.

A–12
PLC Errors for GE SNPX Protocol (Major)
Successful completion. (This is the expected completion value in the COMMREQ Status Word.)
Insufficient Privilege. For Series 90-70 PLC, the minor error code contains the privilege level required for
the service request.
Protocol Sequence Error. The CPU has received a message that is out of order.
Service Request Error, the minor error code contains the specific error code.
Illegal Mailbox Type. Service request mailbox type is either undefined or unexpected.
The PLC CPU's Service Request Queue is full. The master should retry later. It is recommended that the
master wait a minimum of 10 msec before sending another service request.
SNP DOS Driver Error. The minor error code contains the specific error code.
Illegal Service Request. The requested service is either not defined or not supported. (This value is returned
in lieu of the actual 01h value passed in the SNP error message, to avoid confusion with the normal
successful COMMREQ completion.)
Local SNP/SNP-X Error. An error occurred within the SNP task in the CMM module in this PLC.
This error may occur in either an SNP master or an SNP slave. The minor error code contains the specific
error code.
Remote SNP Error. An error occurred within the SNP slave task in the CMM module in the remote PLC.
The minor error code contains the specific error code.
Autodial Error. An error occurred while attempting to send a command string to an attached external
modem. The minor error code contains the specific error code.
SNP-X slave error. An error occurred within the SNPX task in the remote slave device. The minor error
code contains the specific error code.
Port configurator error.
Problem with sending mail to the slave Service Request task.
(Series 90-70 PLC CPUs only)
Problem with getting mail from the slave Service Request task.
(Series 90-70 PLC CPUs only)
Slave SNP task timed out before receiving an SRP response.
(Series 90-70 PLC CPUs only)
Slave SNP task could not find the requested datagram connection.
(Series 90-70 PLC CPUs only)
Slave SNP task encountered an error in trying to write the datagram.
(Series 90-70 PLC CPUs only)
Slave SNP task encountered an error in trying to update the datagram.
(Series 90-70 PLC CPUs only)
