Device part of <Figure 1> input Com Port(COM1), Baud Rate(fixed to 9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.
Also you can input 'received data saving AI tag' by using option part.
DY-500 RTU communication driver’s read schedule
Read schedule setting parameters are as follows:
1) Station – Don't care.
2) Read Memory Type – Don't care.
3) Read Data Type – Read data type. ( Refer to <Table 1> )
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Read data size. ( Fixed, Refer to <Table 1> )

You can write the setting value by using write settings.
Bit Write
Bit write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Write data type.
0001 = Reset of RTU,
0002 = RTU time Synchronization(PC current time),
0008 = Receive start command of RTU saved data. Received data for this command, will save at 'received data saving AI tag'. ( inputed option part tag )
Before using this command, you should set start and end time by using '0008 Word write' command.
0019 = Loging Start/Stop,
0062 = Send EOT data to RTU.
4) Extra1 Don't care.
5) Extra2 Don't care.
Write example 1)
Port:0, Station:0, Address:0001, Extra1: , EXTRA2 :
The setting parameter shown above is Reset of RTU.
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Write data type.
0007 = Setting of AI channel constant value, (Extra2 = setting type)
0008 = Start/End time setting for receiving data, (Extra2 = time sort)
0010 = Setting water level, (above sea level)
0017 = Setting of AI channel,
0018 = Setting of loging period.
4) Extra1 Don't care.
5) Extra2 Setting type or time sort when 'ADDRESS' = 0007 or 0008.
ADDRESS = 0007 : 0 = AD_LOW, 1 = AD_HIGH, 2 = VIEW_LOW, 3 = VIEW_HIGH,
ADDRESS = 0008 : 0 = Data start year, 1 = Data start month, 2 = Data start day, 3 = Data start hour, 4 = Data start minute
10 = Data end year, 11 = Data end month, 12 = Data end day, 13 = Data end hour, 14 = Data end minute,
ADDRESS = Others : Don't care.
Write example 1)
PORT : 0, STATION : 0, ADDRESS : 0010, EXTRA1 : , EXTRA2 :
The setting parameter shown above is a setting example of water level.
