ProcUnit::GetIoModule

Gets I/O module instance

IoModule *GetIoModule(
    TCHAR *ioIdent
)

IoModule *GetIoModule(
    int ioModuleNo
)

Parameters

*ioIdent	I/O module ident name
ioModuleNo	I/O module number

Return Value

I/O module instance.

Description

Gets I/O module instance.

I/O module ident name is as follows:

ParallelIo Parallel I/O

SerialNormal Serial normal

SerialNormal2 Serial normal2

SerialPlcLink Serial PLC link

UdpNormal Ethernet UDP normal

UdpNormal2 Ethernet UDP normal2

UdpPlcLink Ethernet UDP PLC link

I/O module number is as follows:

0:Communication related to Parallel (ParallelIo)

1:Communication related to Serial (SerialNormal/SerialNormal2/SerialPlcLink)

2:Communication related Ethernet (UdpNormal/UdpNormal2/UdpPlcLink)

Example

   void Sample::OutPutData(void *data, int size, ProcUnit *ptrProcUnit)
    {

        // Gets I/O module instance

        IoModule *ptrIoModule0 = ptrProcUnit->GetIoModule(_T("ParallelIo"));

        // Gets I/O module instance

        IoModule *ptrIoModule1 = ptrProcUnit->GetIoModule(IOMODULE_UDP_NO);

    }
