the COMMREQ function and then check for a non-zero value indicating that the Ethernet Interface is responding to the COMMREQ. A good way to do this is to use a MOVE WORD function block to zero the CRS word.

3.A status code of 1 in the low byte and 0 in the high byte indicates that the request was successful. All other non-zero values indicate errors. Refer to the tables below for a complete listing of major and minor error codes.

The following tables list the error codes that are reported in the COMMREQ Status word after the execution of a COMMREQ function. These codes also may appear in Word 1 of the Detailed Channel Status words.

Table 4-4. Major Error Codes

		Error Status	Major Error Description
		Hexadecimal
		01H	Successful Completion. (This is the expected completion value in
			the COMMREQ Status word.)
		02H	InsufficientPrivilege at server PLC. For a 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. Call GE FanucAutomationforassistance.
		05H	Service Request Error at server PLC. The minor error code contains the
			specificerror code. See table of Minor Error codes below.
		06H	IllegalMailbox Type at server PLC. Servicerequestmailbox type is ei-
			ther undefined or unexpected. Call GE FanucAutomationforassistance.
		07H	The server PLC CPUs Service Request Queue is full. The client should
			retry later. It is recommended that the client wait a minimum of 10 mil-
			liseconds before sending another servicerequest.
		0bH	IllegalService Request. The requested service is either not defined or
			not supported at the server PLC. (This value is returned in lieu of the
			actualservice request error (01h), to avoid confusion with the normal
			successfulCOMMREQcompletion.) Call GE FanucAutomation for assis-
			tance.
		11H	SRTP Error Codes at server. An error was detected at the SRTP server.
			See table of Minor Error codes below.
		82H	InsufficientPrivilege at client PLC. For Series 90-70 PLC, the minor er-
			ror code contains the privilege level required for the servicerequest.
		84H	Protocol Sequence Error. The CPU has received a message that is out
			of order. Call GE FanucAutomationforassistance.
		85H	Service Request Error at the client PLC. The minor error code contains
			the specific error code. See table of Minor Error codes below.
		86H	IllegalMailbox Type. Servicerequestmailbox type is either undefined
			or unexpected. Call GE FanucAutomationforassistance.
		87H	The client PLC CPUs Service Request Queue is full. The client should
			retry later. It is recommended that the client wait a minimum of 10 mil-
			liseconds before sending another servicerequest.
		8bH	IllegalService Request. The requested service is either not defined or
			not supported. (This value is returned in lieu of the actual service re-
