KDX-202 장비의 경우 물리적으로 이더넷포트가 달려 있었으며, 

실제 통신 방식은 MODBUS 방식이였기 때문에 통신을 하기위해 공부를 많이 했습니다

제일 먼저 광성계측기 장비의 데이터 맵을 확인하였습니다

테스트를 하기 위해 특정 데이터 코드를 광성계측기 쪽으로 날려줘야 하는데 어떤 것을 날려줄까 

확인을 하다보니 제일 간편한 몇개의 데이터를 요청했습니다

요청 코드 예제 (Data Map 참조)

4. 1 WORD – FF.04.00.00.00.01.24.14

5. 8 WORD – FF.04.00.00.00.08.E4.12

6. 10 WORD – FF.04.00.00.00.0A.65.D3

CRC LO, CRC HI 부분은 각 BYTE 끝에 들어가는 부분인데 구글에서 CRC 계산하는 사이트에서 검색하여 사용 (아래 사이트 참조)

PLC PROGRAM

Parameters

 

Parameter	Declaration	Data Type	Memory Area	Description
REQ	INPUT	BOOL	I, Q, M, D, L	Control parameter REQUEST starts the job for establishing the connection specified by ID. The job starts on the rising edge.
ID	INPUT	WORD	M, D, constant	Reference to the connection to be established to the remote partner or between the user program and the communications level of the operating system. ID must be identical to the associated parameter ID in the local connection description. Range of values: W#16#0001 to W#16#0FFF
DONE	OUTPUT	BOOL	I, Q, M, D, L	DONE status parameter: 0: Job not yet started or still running. 1: Job executed without error.
BUSY	OUTPUT	BOOL	I, Q, M, D, L	BUSY = 1: Job is not yet completed. BUSY = 0: Job is completed.
ERROR	OUTPUT	BOOL	I, Q, M, D, L	ERROR status parameter: ERROR=1: An error occurred in job processing. STATUS returns detailed information on the type of error
STATUS	OUTPUT	WORD	M, D	STATUS status parameter: Error information
CONNECT	IN_OUT	ANY	D	Pointer to the associated connection description (UDT 65), see Assigning Parameters for Open Communications Connections with TCP and ISO on TCP and Assigning Parameters for the Local Communications Access Point with UDP Note: For S7-300 CPUs, please note that the CONNECT parameter always requires the complete specifications of the DB parameter (e.g. P#DB13.DBX0.0 Byte 100). For S7-300 CPUs, leaving out an explicit DB no. is not permitted and causes an error message in the user program.

 

Error Information

 

ERROR	STATUS (W#16#...)	Explanation
0	0000	Connection was established successfully
0	7000	No job processing active
0	7001	Start job processing, establishing connection
0	7002	Follow-on call (REQ irrelevant), connection being established
1	8086	The ID parameter is outside the permitted range.
1	8087	Maximal number of connections reached; no additional connection possible
1	8089	The parameter CONNECT parameter does not point to a data block.
1	809A	The parameter CONNECT parameter points to a field that does not match the length of the connection description (UDT65).
1	809B	The local_device_id in the connection description does not match the CPU or the associated interface is locked.
1	80A0	Group error for error codes W#16#80A1 and W#16#80A2
1	80A1	Connection or port is already occupied by user
1	80A2	Local or remote port is occupied by the system
1	80A3	Attempt being made to re-establish an existing connection
1	80A4	IP address of the remote connection end point is invalid, it may match the local IP address
1	80A7	Communications error: you have called TDISCON before TCON was complete. TDISCON must first complexly terminate the connection referenced by the ID.
1	80B2	The parameter CONNECT parameter points to a data block that was generated with the keyword UNLINKED.
1	80B3	Inconsistent parameter assignment: Group error for the error codes W#16#80A0 to W#16#80A2, W#16#80A4, W#16#80B4 to W#16#80B9
1	80B4	When using the protocol variant ISO on TCP (connection_type = B#16#12) for passive establishment of a connection (active_est = FALSE), you violated one or both of the following conditions: local_tsap_id_len >= B#16#02 local_tsap_id[1] = B#16#E0 With local_tsap_id_len >= B#16#03, local_tsap_id[1] is an ASCII character local_tsap_id[1] is an ASCII character and local_tsap_id_len >= B#16#03
1	80B5	Error in active_est parameter (UDT 65) in the UDP protocol variant
1	80B6	Parameter assignment error relating to the connection_type parameter (UDT 65)
1	80B7	Error in one of the following parameters of UDT 65: block_length, local_tsap_id_len, rem_subnet_id_len, rem_staddr_len, rem_tsap_id_len, next_staddr_len
1	80B8	Parameter ID in the local connection description (UDT 65) and parameter ID are different
1	80C3	All connection resources are in use.
1	80C4	Temporary communications error: The connection cannot be established at this time. The interface is receiving new parameters. The configured connection is currently being removed by a TDISCON. The H system is connecting and updating.
1	8xyy	General error information, see Error Evaluation with the Output Parameter RET_VAL
