Output Description

BUSY

Data_Type	Default_Value	Range	Unit
BOOL	FALSE	-	-

Block Process bit. This output always has to be considered together with output ERR. If ERR is TRUE, an error occurred. In this case, the error number can be read at output RUNTIME_ERROR / CONFIG_ERROR.

ERR

Data_Type	Default_Value	Range	Unit
BOOL	FALSE	-	-

Error occurred during execution when output ERR = TRUE.

CFG_ERROR

Data_Type	Default_Value	Range	Unit
WORD	0	-	-

Each bit of the WORD represents different configuration errors:

Bit0 - CI module configuration mis-match,

Bit1 - SYNC_SLOT invalid,

Bit2 - SEC_SLOT invalid,

Bit3 - IP_ADR_CPU_A1 invalid,

Bit4 - IP_ADR_CPU_B1 invalid,

Bit5 - IP_ADR_CPU_A2 invalid,

Bit6 - IP_ADR_CPU_B2 invalid,

Bit7 - IP_ADR_CPU_A1=IP_ADR_CPU_B1 or IP_ADR_CPU_A2=IP_ADR_CPU_B2.

CFG_ERROR is valid only when ERR = TRUE

RUNTIME_ERROR

Data_Type	Default_Value	Range	Unit
WORD	0	-	-

Each bit of the WORD represents different Runtime errors:

Bit0 - CI module lost,

Bit1 - Other CPU not active,

Bit2 - Lifecom1 is lost (part of Sync),

Bit3 - Lifecom2 is lost,

Bit4 - Sync lost,

Bit5 - Error in Sync,

Bit6 - Ethernet status,

Bit7- Other PLC Lost communication to CI52x,

Bit8- Not used,

Bit9- Not used,

Bit10- GetOwnIP function block has error.

Note

RUNTIME Errors may occur during operation, but they will not generate ERR output = TRUE. This allows the system to run and revert to an error free state.

Note

Bit3 - Lifecom2 is lost RUNTIME ERROR will not be TRUE if the PLC is in STOP status. This is because Modbus is still responding even when PLC is in STOP.

CFG

Data_Type	Default_Value	Range	Unit
WORD	0	-	-

Bit0 - Not used,

Bit1 - Sync via UDP enabled,

Bit2 - Not used,

Bit3 - Not used,

Bit4 - LifeCom2 via Modbus TCP is enabled,

Bit5 - Initialization for Ethernet configuration.
