CiModCi52x (FB)

FUNCTION_BLOCK CiModCi52x EXTENDS AbbLConCA

CiModCi52x Function block is used to establish the communciation between AC500 PLC and Fieldbus Modbus module CI521 or CI522 Using this function block, status of the CI52x module configured in the network can be known. The diagnosis info (CiModCi52x Function block outputs) from CI module can be read out only once. e.g. If secondary CPU has read CI module and afterwards change happens in CI52x diagnosis, then it is not reflected in secondary CPU, leading to different diagnosis information in Primary and Secondary CPU. Hence it is recommended to the user that the diagnosis info should be handled in application program e.g. should be synchronized in a separate structure OR handled on SCADA side.

Note: CiModCi52x function block disabling (Enable = FALSE) will not set output “RuntimeError Bit 0” (Bit 0 - CI module lost error) on HaModControl function block

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Enable	BOOL	FALSE	A rising edge (Enable = TRUE) starts the operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. A falling edge (Enable = FALSE) aborts the operation. During Aborting the Busy is still TRUE. Afterward all outputs are reset.	AbbLConCA
Output	Busy	BOOL	FALSE	Operation is running (while output Error is FALSE)	AbbLConCA
	Error	BOOL	FALSE	Operation is stopped with error (while output Busy is FALSE). This output is TRUE for at least one cycle or until Enable is set to FALSE. The output ErrorID gives more details about the error.	AbbLConCA
Input	ConfigIP	STRING(15)		2: IP Address of the IO Module
	ConfigEth	BYTE	0	3: Ethernet Slot used for communication on the PLC. Input is ignored, existing only for compatibility reason
	Para0	DWORD	0	4: Busmodule Configuration Address
	Data0	DWORD	0	5: Bus module IO Structure address
	Para1	DWORD	0	6: IO module 1 configuration address
	Data1	DWORD	0	7: IO module 1 IO Structure address
	Para2	DWORD	0	8: IO module 2 configuration address
	Data2	DWORD	0	9: IO module 2 IO Structure address
	Para3	DWORD	0	10: IO module 3 configuration address
	Data3	DWORD	0	11: IO module 3 IO Structure address
	Para4	DWORD	0	12: IO module 4 configuration address
	Data4	DWORD	0	13: IO module 4 IO Structure address
	Para5	DWORD	0	14: IO module 5 configuration address
	Data5	DWORD	0	15: IO module 5 IO Structure address
	Para6	DWORD	0	16: IO module 6 configuration address
	Data6	DWORD	0	17: IO module 6 IO Structure address
	Para7	DWORD	0	18: IO module 7 configuration address
	Data7	DWORD	0	19: IO module 7 IO Structure address
	Para8	DWORD	0	20: IO module 8 configuration address
	Data8	DWORD	0	21: IO module 8 IO Structure address
	Para9	DWORD	0	22: IO module 9 configuration address
	Data9	DWORD	0	23: IO module 9 IO Structure address
	Para10	DWORD	0	24: IO module 10 configuration address
	Data10	DWORD	0	25: IO module 10 IO Structure address
	Ack	BOOL	FALSE	26: Acknowledge
Output	Run	BOOL	FALSE	3: If TRUE - CI52x module is running
	CfgError	BYTE	0	4: Each bit of the byte represents different configuration errors: Bit0 - reserved, Bit1 - ConfigEth invalid, Bit2 - ConfigIP invalid
	RuntimeError	BYTE	0	5: Each bit of the byte represents different Runtime errors: Bit0 - communication error, Bit1 - IO bus error i.e. parameter state is wrong , Bit2 - cluster error i.e. Diagnostic buffer has error, Bit3 - HW configuration error, Mismatch between configuration and actual hardware detected Bit4 - HW configuration error, too much IO Data-> reduce IO modul to new Cluster
