NOTE
 
_DMC_01_get_device_table
 
 Get the Slot ID using the PDO protocol
 
Example: gpDeviceInfo[gDMCCardNo] is a “WORD” type variable. If its value is 7, 
the binary form is expressed as “
0000 0000 0000 0111”,
 so Slave devices with Slot 
IDs “1”, “2” and “3” exist. 
_DMC_01_get_node_table
 
 Get Node ID using SDO protocol. 
 
Example: gpSlaveTable[0][gDMCCardNo] is a “DWORD” type variable. If its value is 
7, the binary form is expressed as “
0000 0000 0000 0000 0000 0000 0000 0111”,
 so 
Slave devices with Node ID “1”, “2”, and “3” exist.   
 
※You can use the following algorithm to find the Node ID for SDO.   
lMask = 0x1; 
for(i=0; i<32; i++)   
/* Condition is met when the i-th bit is 1. */ 
if((gpSlaveTable[0][gDMCCardNo]>>i) & lMask) { 
/* The derived i-th value +1 is the Node ID and corresponds to servo parameter 
“P3-00” */ 
gpNodeID[gNodeNum] = (unsigned short)(i+1);   
gNodeNum++; 
 
4) Exit procedure 
 
Figure 3.5 
 
Click on the “Exit” button to execute the following procedure: 
for(i=0; i<gDMCExistCards; i++) { 
rt = _DMC_01_reset_card(gpDMCCardNoList[i]); 
// Reset card
 

_DMC_01_close();  
// Shut down PCI-DMC-A01
