Re: Anybody using modtcp and Wago?

[Ivan So <so@bnl.gov>]

We (NSLS Beamline Controls) are using modtcp and Wago under Linux and 
VxWorks.

The original code was from Triumf, Canada.

I need to change the offset with BO_OFFSET in drvModtcp.c:

#define WAGO

#if defined(WAGO)
unsigned short BO_OFFSET=0x200;
#else
unsigned short BO_OFFSET=0x0;
#endif

===============================================

int modtcpWrite(int index, int addr, unsigned short mask, unsigned short 
*pData)
{
       PLC_ID pPlc;
       SOCKET_ID pSock;
       int i, error, ok;
       unsigned short outval, *pOut;

       pPlc = Plcs[index];
       if (!pPlc->pSock2->tcpsFd) return -1;

       pOut = pPlc->memStart + addr + BO_OFFSET - 1;

==================================================

                       /* set pFrom pointer to begin of EPICS local 
buffer or to VME slave memory (SDLC) */
                       if (pGr->readAddr < pPlc->memLength) pFrom  = 
pPlc->memStart + pGr->readAddr + BO_OFFSET - 1;

===================================================

Just to give you some ideas.

I am going to clean this up after  other higher priority  jobs.  May  be 
then we could generate some useful diff's for you.

Good luck.
