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.

INDEX   BYTE \    (index \ of connection)

Index of the standard UDP/IP connection corresponding to the PLC configuration, starting with 0. The Function Block only works on the connection that was selected by this input, and with the parameters set in the PLC configuration, e.g. port, buffer size, behaviour in case of buffer overflow etc.

DATA   DWORD \    (data)

Input DATA is used to specify the address of the variable to which the user data shall be copied. The address specified at DATA has to belong to a variable of the type ARRAY or STRUCT.
