Input DescriptionΒΆ
EN
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
The Function Block is activated (EN = TRUE) or deactivated (EN = FALSE) via input EN. If the Function Block is active, the current values are available at the outputs. If the Function Block detects a CAN Communication Module with a configured CAN 2.0A protocol at the specified SLOT, this is indicated by DONE = TRUE and ERR = FALSE. The corresponding status information is then available at the Function Block outputs.
SLOT
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BYTE | - | - | - |
At input SLOT, the Communication Module slot (module number) is selected to used by the Function Block.
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 | - | - | - |
The input TYP is used to select the type of status survey displayed at output NODE.
TYP = 1 Configuration survey
Output NODE displays which slaves are successfully connected to the master (TRUE). Please note that the master only establishes connections to slaves that have been announced to the master during the definition of the configuration data.
TYP = 2 Operational survey
Output NODE displays which slaves are error-free and in operation. A slave can only be announced as operational if it has been configured in the master. The operational survey can only be requested if the Communication Module is in OPERATE state.
TYP = 3 Diagnosis survey
Output NODE indicates which slaves report a diagnosis. The diagnosis survey can only be requested if the Communication Module is in OPERATE state.
