Device part of <Figure 1> input Device Type(TCP/IP), IP address of PLC(192.168.1.48), service port number(5078) respectively, according to setting of server.
In protocol option part, you can set the following: user ID ( 0 ~ 65535, defalut = 110), sending interval for status monitoring data ( 0 ~ 65535 mSec, default = 2000 ), status monitoring data start address of DWORD memory ( 0 ~ 65535, default = 0 ), DC setting data start address of WORD memory ( 0 ~ 65535, default = 100 ), readed command and status data saving start address of WORD memory ( 0 ~ 65535, default = 0 ), main folder for report file( default = \Data ), weather to use auto-setting when DC setting Write command( 0 : use, 1 : don't use, default = 1 ). Each argument is a comma-delimited.
BAMS DC System communication driver read schedule
Read schedule setting parameters are as follows:
1) Station address – don't care.
2) Read command – command = fixed to STS.
3) Read start address – don't care.
4) Save start address for Communication Server – don't care.
5) Read Size – fixed to 1.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> will be shown.
You can send ACK confirm, time syncronization command to Server by using write settings.
Digital write
Digital write and analog write have the same setting parameters except output value(0 or 1).
Analog write
Analog write setting parameters are as follows:
1) PORT port no. (0 ~ 255)
2) STATION data saving year when DAY, MON, RMU command.
3) ADDRESS data saving month or day when DAY, MON, RMU command.
DAY, RMU write command : higher 2 digit = month, lower 2 digit = day, ( 0527 : month = 05, day = 27 )
MON write command : data saving month.
4) EXTRA 1 write command = ACY, SYNC, DAY, MON, EVENT, RMU.
ACK : ACK confirm sending command to BAMS Server,
SYNC : time syncronization request command to BAMS Server.
DAY, MON, EVENT, RMU write command : data saving command for day, month, event, RMU day report request command from BAMS Server. ( data saving folder is 'main folder for report file' )
5) EXTRA 2 data saving contents when DAY, MON, EVENT, RMU command.
DAY : 0 ~ 95 = 15 minutes demand power, 100 = target power of the day,
MON : 1 ~ 31 = amount of power for each day( KWh ),
EVENT : 1 ~ 6 event code ( 1 = system error, 2 = BAMS server communication error, 3 = RMU RS-485 communication error, 4 = RMU control, 5 = RMU return(release control), 6 = RMU Fail ),
RMU : 0 ~ 95 = RMU accumulated power ( KWh, 24hour x 4 )
6) Output Value data saving contents when DAY, MON, EVENT, RMU write command.
DAY : 15 minutes demand power value or target power value of the day ( Extra2 = 100 ),
MON : amount of power value for each day( KWh ),
EVENT : event code data ( normally RMU ID ),
RMU : RMU accumulated power value ( KWh ).
Write example 1)
PORT:0, station:0, ADDRESS:0000, Extra1:ACK, Extra2 : 0
The setting parameter shown above is ACK confirm sending command to Server.
Write example 2)
PORT:0, station:0, ADDRESS:0000, Extra1:SYNC, Extra2 : 0

Write example 3)
PORT:0, station:2014, ADDRESS:0527, Extra1:DAY, Extra2 : 0
The setting parameter shown above is Day report data saving example for 1st 15 minutes demand power at 'main folder for report file'.
Write example 4)
PORT:0, station:2014, ADDRESS:0527, Extra1:DAY, Extra2 : 100
The setting parameter shown above is Day report data saving example for target power value of the day at 'main folder for report file'.
Write example 5)
PORT:0, station:2014, ADDRESS:005, Extra1:MON, Extra2 : 27
The setting parameter shown above is Month report data saving example. The saving data is amount of power value for 2014-05-27.
