Input DescriptionΒΆ
EN
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
If a FALSE->TRUE edge is applied to input EN, all further inputs are read. If the input values are valid, a corresponding request message is sent to the Communication Module. While this request message is processed, output DONE is set to FALSE. If at least one input value is invalid, an error is indicated at the outputs ERR and ERNO and the termination of the request processing is indicated by DONE = TRUE.
During the processing of a request, state changes at input EN are recognized but not evaluated.
SLOT
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BYTE | - | - | - |
At input SLOT, the Communication Module slot (module number) to be used by the Function Block is selected.
The internal Communication Module always has the module number 0. All external Communication Modules are serially numbered from right to left, starting with module number 1.
TYP
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BYTE | - | - | - |
Input TYP is used to select the type of status survey to be displayed at output DEV.
TYP = 1 Configuration survey
Output DEV displays all slaves that are successfully connected to the master. Please note that the master only establishes connections to slaves which have been assigned to the master during the definition of the configuration data.
TYP = 2 Data exchange survey
Output DEV displays the slaves with which the master is exchanging I/O data. Data exchange can only be performed with slaves that have been configured by the master itself. The data exchange survey can only be requested, if the Communication Module is in OPERATE state.
TYP = 3 Diagnosis survey
Output DEV indicates which slaves report a diagnosis. The diagnosis survey can only be requested if the Communication Module is in OPERATE state.
