Input DescriptionΒΆ
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.
ETH BYTE \ (ETHERNET index number)
At input ETH, the ETHERNET index number is specified. The assignment is as follows:
| 1 | ETHERNET interface at Onboard ETHERNET 1 |
| 2 | ETHERNET interface at Onboard ETHERNET 2 |
| 11 | ETHERNET interface at Communication Module slot 1 *) |
| 21 | ETHERNET interface at Communication Module slot 2 *) |
| 31 | ETHERNET interface at Communication Module slot 3 *) |
| 41 | ETHERNET interface at Communication Module slot 4 *) |
| 51 | ETHERNET interface at Communication Module slot 5 *) |
| 61 | ETHERNET interface at Communication Module slot 6 *) |
*) The Communication Modules are serially numbered from right to left, starting with module number 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.
CAUTION: Set the variable size to the maximum expected amount of data in order to avoid overlapping of memory areas.
