Description

Use the CC_PLC_BTW function to put block-transfer information to an

analog I/O module. This function may take a long period of real time

to complete.

C Example

unsigned char rack = 0;

unsigned char group = 5;

unsigned char module = 0;

unsigned char size = 1;

unsigned iostat;

unsigned short buff;

buff = 0x23;

status = CC_PLC_BTW (rack,group,module,size,1,&buff,&iostat);

if (!(status))printf (“data sent to module\n”);
