Delta DVP Series PLC Communication driver’s read schedule

Read schedule setting parameters are as follows:

1)     STATION - Input station ID between 0 ~ 255.

2)     Read memory type - Memory type = S, X, Y, M, T, C, D. (Refer to <Table 1>)

3)     Read Start Address – Read start address in each memory type.

4)     Save Start Address for Communication Server - Input save start address of communication server.

5)     Read Size - Set the size of the read. Read size = 1 ~ 100.

Read size of BYTE memory type(DB, Db, …) = BYTE unit(1byte),

Read size of WORD memory type(D, DW, …) = WORD unit(2byte),

Read size of double WORD memory type(DD, Dd, …) = Double WORD unit(4byte),

Read size of FLOAT memory type(DF, Df, DF2, …) = float unit(4byte),

Read size of DOUBLE memory type(DFD, DfD, …) = double unit(8byte),

 

Read schedule example

2. Writing settings

You can change the setting values of Delta DVP Series PLC by using write commands.

 

 

Bit write

Bit write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION               Input station ID between 0 ~ 255.

3)  ADDRESS            Top 3-digit (decimal): 0 ~ WORD unit address in Memory type.

last 1-digit (in hexadecimal): 0-F bit pos.

4)  Extra1                   Memory type = S, X, Y, M, T, C.

5)  Extra2                   Don’t care.

 

Write example 1)

PORT : 0   STATION : 1   ADDRESS : 0005  EXTRA1 : S  EXTRA2 : 0

The setting parameter shown above is an example of bit write(ON/OFF) in S memory 0 WORD, 5 BIT of Delta DVP Series PLC connected with 0 port, set to 1 station.

 

Write example 1)

PORT : 0   STATION : 1   ADDRESS : 001F  EXTRA1 : S  EXTRA2 : 0

The setting parameter shown above is an example of bit write(ON/OFF) in S memory 1 WORD, F BIT of Delta DVP Series PLC connected with 0 port, set to 1 station.

 

Setup example 2)

PORT : 0   STATION : 1   ADDRESS : 005A  EXTRA1 : S  EXTRA2 : 0

The setting parameter shown above is an example of bit write(ON/OFF) in S memory 5 WORD, A BIT of Delta DVP Series PLC connected with 0 port, set to 1 station.

 

 

Word write

Word write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION               Input station ID between 0 ~ 255.

3)  ADDRESS            0 ~ WORD unit address(decimal) in Memory type.

4)  Extra1                   Memory type = T, C, D.

D, DD, Dd, DF, Df, DF2, DFD, DfD, … memory type can be set(Refer to <Table 1>).

5)  Extra2                   Don’t care.

 

 

Write example 1)

PORT : 0   STATION : 1   ADDRESS : 0000  EXTRA1 : D  EXTRA2 : 0

The setting parameter shown above is an example of word write in D memory 0 WORD address of Delta DVP Series PLC connected with 0 port, set to 1 station.

The setting parameter shown above is an example of word write in D memory 123 WORD address of Delta DVP Series PLC connected with 0 port, set to 1 station.

 

 

Block write

Block write comes to be executed by ‘PlcScanWriteBlock’ script function.

Available script variables are ushort, uint, float, double.

You can write to T, C, D PLC memory such as DD, Dd, DF, Df, DF2, DFD(Refer to <Table 1>).

 

Script name and format: @PlcScanWriteBlock(int port, int station, int address, string extra1, string extra2, object array_value, int array_size);

   Scripting example 1)

If you want to set by 12, 13, 14, 15 in D memory 5, 6, 7, 8 WORD format address.

 

             ushort   writeVal[4];

 

             writeVal[0] = 12;

writeVal[1] = 13;

writeVal[2] = 14;

writeVal[3] = 15;

@PlcScanWriteBlock(0, 0, 5, “D”, “”, writeVal, 4);

 

   Scripting example 1)

If you want to set by 1.1, 1.2, 1.3, 1.4 in D memory 10, 12, 14, 16 Float LO/HI word format address.

 

             float   fWriteVal[4];

 

             fWriteVal [0] = 1.1;

fWriteVal [1] = 1.2;

fWriteVal [2] = 1.3;

fWriteVal [3] = 1.4;

@PlcScanWriteBlock(0, 0, 10, “Df”, “”, fWriteVal, 4);

 

 

Important) Block write is available only WORD/DWORD/FLOAT/DOUBLE unit.

Also Block write is supported 10.1.4.3 version or higher.
