Return Values

Note
Before executing any functions on the I-8026W, the i8026W_Init function needs be called once
for each I-8026W module inserted in the controller unit. For example, if there are two or more
I-8026W modules inserted in the controller, the i8026W_Init function must be individually
called for each I-8026W module by including the number of the slot where the I-8026W
module is inserted.
Example
[C]
int slotIndex ,err;
Open_Slot(slotIndex);
err=i8026W_Init(slotIndex);
if(err==0)
printf("There is an I-8026W module in slot %d\n",slotIndex);
else
printf("There is no I-8026W module in slot %d\n",slotIndex);
