Description

Use the DTL_WRITE_W function to write data to the PLC-5

programmable controller directly connected to the control coprocessor.

This function is synchronous. When this function is initiated, your

C application program stops until the function completes or fails.

C Example

unsigned status;

unsigned machine1;

unsigned short parts1;

unsigned iostat;

DTL_C_DEFINE (&machine1, “N30:0, 1, WORD, MODIFY”);

status = DTL_WRITE_W (machine1, &parts1, &iostat)

if (status == DTL_SUCCESS)

{

printf (“parts = %d\n”, parts1);

}

else

{

(printf (“error %d, %d on read of parts data\n”,

status,

iostat);

}
