Major Error Codes in the COMMREQ Status Word
Success or a Major Error Code appears in the low byte of the COMMREQ Status Word. Hexadecimal values for
the low byte are listed below. For many Major Error Codes, additional information appears as a Minor Error

following pages.
Error Status
(Hexadecimal)
Major Error Code Description
01H
Successful Completion. (This is the expected completion value in the COMMREQ Status word.)
02H
Insufficient Privilege at server PLC. For a PACSystems or Series 90-70 server PLC, the minor
error code contains the privilege level required for the service request.
04H
Protocol Sequence Error. The server CPU has received a message that is out of order. Contact
Technical Support for assistance.
05H
Service Request Error at server PLC. The minor error code contains the specific error code.
See the following table of Minor Error codes.
06H
Illegal Mailbox Type at server PLC. Service request mailbox type is either undefined or
unexpected. Contact Technical Support for assistance.
07H
The server PLC CPU’s Service Request Queue is full, usually due to heavy CPU loading. The
client should retry later. It is recommended that the client wait a minimum of 10 milliseconds
before sending another service request.
0BH
Illegal Service Request. The requested service is either not defined or not supported at the
server PLC. (This value is returned in lieu of the actual service request error (01H), to avoid
confusion with the normal successful COMMREQ completion.) Contact Technical Support for
assistance.
11H
SRTP Error Code at server. An error was detected at the SRTP server. See the following table
of Minor Error codes.
82H
Insufficient Privilege at client PLC. The minor error code contains the privilege level required
for the service request.
84H

(Some EGD command errors also use major code 90 when indicating the same error
condition as channels.)
