Input Description

EN

Data_Type	Default_Value	Range	Unit
BOOL	FALSE	TRUE/FALSE	-

The input EN has to be driven in level triggered mode.

In order to enable the execution of the Function Block the input EN has to be set to value TRUE. It keeps on executing until the input EN is set back to value FALSE.

While it is executed its inputs are continuously evaluated.

SLOT

Data_Type	Default_Value	Range	Unit
BYTE	0	0 … 4 (6)	-

At input SLOT, the Communication Module slot is specified which should be used by the Function Block.

The internal Communication Module always has the index 0. All external Communication Modules are serially numbered from right to left, starting with 1.

DEV_NAME

Data_Type	Default_Value	Range	Unit
STRING	-	-	-

Input DEV_NAME describes the PROFINET IO Device to be queried. The string has a maximum length of 240 characters, including the zero terminating char. In conjunction with the SLOT value this string selects the target IO device of this request.

Valid values are (examples for the ABB devices, the hash marks # are place holders for the address selected by the rotary switch at the front of the device):

ci506-pn-##

TYP

Data_Type	Default_Value	Range	Unit
BYTE	-	-	-

Input TYP selects the type of CANOPEN system diagnosis displayed at output NODE.

TYP = 1 Configured slaves

Output NODE displays which slaves are configured for the CANOPEN master in CI506 (TRUE).

TYP = 2 Operational slaves

Output NODE displays which slaves are error-free and in operation. A slave can only be operational if it has been configured in the master. The type of system diagnosis can only be requested if the CANOPEN master is in OPERATE state.

TYP = 3 Slaves with diagnosis

Output NODE indicates which slaves report a diagnosis. The diagnosis survey can only be requested if the CANOPEN master is in OPERATE state.

MASTER_NODE

Data_Type	Default_Value	Range	Unit
BYTE	-	1 - 127	-

Input MASTER_NODE describes the CANOPEN master node ID in CI506.
