DNP KEPCO10 Communication Driver is the driver to communicate with DNP3.0 protocol.
Note) DNP KEPCO10 communication driver can use only one driver at one device.
If you want to use twor or more driver at multi device, you can use DNP KEPCO10 Add 01 ~ DNP KEPCO10 Add 16 driver. ( max = 17 driver)
<Figure 1> is read setting example of DNP KEPCO10 communication driver.

Device Setting of <Figure 1> are input, device type( UDP/IP ), IP address of DNP controller( 210.180.41.20 ), service port address( 13000 )respectively, according to setting of controller.
Read Cycle of DNP KEPCO10 communication driver should alway be set to 0.
Read/Write TimeOut can be set to more than 5,000 mSec( 5 second ).
Also DNP source address(0 ~ 65534, default = 2), alarm number when accur SOE ( Class 1 ) Data(0 ~ 999, default = 100), alarm number when accur COS ( Class 2 ) Data(0 ~ 999, default = 101), alarm number when accur Class 3 Data(0 ~ 999, default = 102), whether to save the alarm data of Class(0 = do not save, 1 = save, default = 0), memory saving type of accurred SOE(WORD, DWORD, FLOAT, default = DWORD), memory saving start address of accurred SOE(0 ~ 9999, defalut = 0), memory saving type of accurred COS(WORD, DWORD, FLOAT, default = DWORD), memory saving start address of accurred COS(0 ~ 9999, defalut = 0), memory saving type of accurred Class 3(WORD, DWORD, FLOAT, default = DWORD), memory saving start address of accurred Class 3(0 ~ 9999, defalut = 0) are set by using option part (separated by commas each parameter).
DNP KEPCO10 communication driver¡¯s read schedule
Read schedule setting parameters are as follows:
