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 FPΣ.
Variables of this function block have to be of one of the following data types:
Inputs
Data type Input
INT iUnitSlotNumber
INT NetworkType
BOOL DataExchange_bRun
POINTER DataExchange_pInputData
POINTER DataExchange_pOutputData
BOOL SlaveDiagnostic_bStart
INT SlaveDiagnostic_iNumber
BOOL bMasterReset
Outputs
Data type Output
BOOL Unit_blsReady
INT Unit_ErrorNumber
DUT dutNetworkStatus
BOOL[128] Slaves_abIsConfigured
BOOL[128] Slaves_abIsConnected
BOOL[128] Slaves_abHasDiagnostic
36
Function
Installation position of the FMU.
Use:
• FMU_ProfibusDP
• FMU_DeviceNet
• FMU_CANopen
Defined in the library as VAR_GLOBAL_CONSTANT.
If true, network communication runs.
Pointer to the input's process data table.
Pointer to the output's process data table.
If rising edge, slave diagnostic starts on time.
Node number for diagnostic.
If true, the unit is in reset stage.
Function
ON if unit is ready.
Unit is in error.
