Data Send from Master Communication Driver

Data Send from Master Communication Driver is the driver in order to transmit the specific data to electronic display board.

1. Read settings

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to master equipment.

Data Send from Master communication driver’s read schedule 

Data Send from Master communication driver's read schedule input 'READ' one line.

Read schedule example) 

READ,     ,    ,     0,     0,   1, 

2. Writing settings

You can transmit the specific data to DPM by using write settings.

Bit Write

Bit write and word write have the same setting parameters except output value.( 0 or 1 )

Word Write

Word write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Writing item of DATA or E3 command. 1 = water level(cm unit),  2 = current output(W unit), 3 = annul accumulate power(W unit), 4 = total accumulate power(W unit),

Other command = don't care.

3)  ADDRESS           Data saving address(WORD, DWORD, FLOAT memory) of writed value.

4)  Extra1                   Write command.

ONOFF or 16 : electronic display board On/Off command, ( writing value = 0 or 1 )

LED or 1A : electronic display board 'bright' setting command, ( writing value = 0 ~ 255 )

DATA or E3 : electronic display board 'data' setting command, ( writing value = double word data )

5)  Extra2                   Writing color of DATA or E3 command. 1 = G(green),  2 = Y(yellow), 0, 3, ... = R(red),

Other command = don't care.

Write example 1)

PORT : 0   STATION : 0   ADDRESS : 0000  EXTRA1 : ONOFF  EXTRA2 : 

The setting parameter shown above is an example of 'On/Off' control at current connected electronic display board.

After write, the writed data save '0 WORD, DWORD, FLOAT' memory.

Write example 2)

PORT : 0   STATION : 0   ADDRESS : 0001  EXTRA1 : LED  EXTRA2 : 

The setting parameter shown above is an example of 'bright' setting at current connected electronic display board.

After write, the writed data save '1 WORD, DWORD, FLOAT' memory.

Write example 3)

PORT : 0   STATION : 1   ADDRESS : 0002  EXTRA1 : DATA  EXTRA2 : 0 

The setting parameter shown above is an example of water level 'data' setting with 'red' color.

After write, the writed data save '2 WORD, DWORD, FLOAT' memory.

Write example 4)

PORT : 0   STATION : 2   ADDRESS : 0003  EXTRA1 : DATA  EXTRA2 : 0 

The setting parameter shown above is an example of current output 'data' setting with 'red' color.

After write, the writed data save '3 WORD, DWORD, FLOAT' memory.

Write example 5)

PORT : 0   STATION : 3   ADDRESS : 0004  EXTRA1 : DATA  EXTRA2 : 1 

The setting parameter shown above is an example of annul accumulate power 'data' setting with 'green' color.

After write, the writed data save '4 WORD, DWORD, FLOAT' memory.

Write example 6)

PORT : 0   STATION : 4   ADDRESS : 0005  EXTRA1 : DATA  EXTRA2 : 2 

The setting parameter shown above is an example of total accumulate power 'data' setting with 'yellow' color.

After write, the writed data save '5 WORD, DWORD, FLOAT' memory.
