1. Read settings

 

<Figure 1> is read setting example of Combinet-Network Wireless PLC communication driver.

<Figure 1>  Read setting example of Combinet-Network Wireless PLC communication driver

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

Combinet contrller can set baud rate, etc by using 'setting button',

 

Combinet-Network Wireless PLC communication driver¡¯s read schedule 

Read schedule setting parameters are as follows:

1) STATION – Unit address and computer number = 0 ~ 255 or 0 ~ 65535(high byte = computer number).

2) Read command – Read memory type = X, Y, M, K, F, A, B, W, L, D, G. ( Refer to <Table 1> )

3) Read Start Address Read start address of memory type. ( X, Y, M, K, F, A = word unit address, 1 = 10h )

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – Word unit read data size.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.

 

2. Writing settings

You can write Combinet-Network Wireless PLC by using write settings.

 

Bit Write

Bit write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Unit address and computer number = 0 ~ 255 or 0 ~ 65535(high byte = computer number).

3)  ADDRESS           Bit write address of memory.

Upper 3 ~ 7 digit : X, Y, M, K, F, A memory = hexadecimal nunber( x 16 ), else memory = decimal number(  x 10 ),

Lower 1 digit : 0 ~ F bit position of 'X, Y, M, K, F, A' memory type.

4)  Extra1                   Write command = X, Y, M, K, F, A, B, W, L, D, G. ( Refer to <Table 1> )

5)  Extra2                   Don't care.

 

Write example 1)

PORT : 0   STATION : 1   ADDRESS : 000A  EXTRA1 : M  EXTRA2 : 0

The setting parameter shown above is an example of bit write for 'A'(11th) bit of M memory of Combinet-Network Wireless PLC.

 

Write example 2)

PORT : 0   STATION : 1   ADDRESS : 003A  EXTRA1 : M  EXTRA2 : 0

The setting parameter shown above is an example of bit write for '3A'(59th) bit of M memory of Combinet-Network Wireless PLC.

 

Word Write

Word write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Unit address and computer number = 0 ~ 255 or 0 ~ 65535(high byte = computer number).

3)  ADDRESS           Decimal uint word write address of memory.

 X, Y, M, K, F, A memory = address x 16, else memory = decimal address,

4)  Extra1                   Write command = X, Y, M, K, F, A, B, W, L, D, G. ( Refer to <Table 1> )

5)  Extra2                   Don't care.

 

Write example 1)

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

The setting parameter shown above is an example of word write for '0' word of M memory of Combinet-Network Wireless PLC.

 

Write example 2)

PORT : 0   STATION : 1   ADDRESS : 0015  EXTRA1 : W  EXTRA2 : 0

The setting parameter shown above is an example of word write for '15' word of W memory of Combinet-Network Wireless PLC.

 

Write example 3)

PORT : 0   STATION : 1   ADDRESS : 0021  EXTRA1 : L  EXTRA2 : 0

The setting parameter shown above is an example of double word write for '21' double word of L memory of Combinet-Network Wireless PLC.

 

Write example 4)

PORT : 0   STATION : 1   ADDRESS : 0032  EXTRA1 : D  EXTRA2 : 0

The setting parameter shown above is an example of float write for '32' double word of D memory of Combinet-Network Wireless PLC.
