5.3 FMU_DataExchange
The FMU_DataExchange function block is used to start communication with the network. It has
to be supplied with information about the input and output size, and network-specific data.
Just leave the pins unconnected that you do not require.
PLC types: available for FP2/FP2SH and FP
Σ
.
Variables of this function block have to be of one of the following data types:
Inputs
Data type Input Function
INT iUnitSlotNumber Installation position of the FMU.
INT NetworkType Use:
•
FMU_ProfibusDP
• FMU_DeviceNet
•
FMU_CANopen
Defined in the library as VAR_GLOBAL_CONSTANT.
BOOL DataExchange_bRun If true, network communication runs.
POINTER DataExchange_pInputData Pointer to the input's process data table.
POINTER DataExchange_pOutputData Pointer to the output's process data table.
BOOL SlaveDiagnostic_bStart If rising edge, slave diagnostic starts on time.
INT SlaveDiagnostic_iNumber Node number for diagnostic.
BOOL bMasterReset If true, the unit is in reset stage.
Outputs
Data type Output Function
BOOL Unit_blsReady ON if unit is ready.
INT Unit_ErrorNumber Unit is in error.
