Sets a block of addresses to communicate.

Select the device first (M, Q, I, PI, C, T, DB1~255.DB) and enter the address.

In case of DB device but greater than 256, set the address type as DB_No.No and enter the address as the example below.

 

DB greater than 256.

Address type : DB_No.No

Address : DB Block number.Starting Address

Ex) DB_No.No  700.20     =>   DB700.DBW20

Count and Timer only supports writing of BCD16 or UBCD16 data type. The data range is 0 ~ 999.

Bit addresses

Enter X to the device type.( MX, QX, IX, PIX, CX, TX, DB1~65535.DBX )

Then enter the address.

 

[DB]

DB is formatted as DB[DB Number].[DBX][Byte address number].[Bit location].

Bit location ranges from 0 to 7.

 

[M]

MX [Byte address] . [Bit location]

Byte addresses

Enter B to the device type. (MB, QB, IB, PIB, CB, TB, DB1~65535.DBB )

Then enter the address in byte unit.

 

[DB]

DB is formatted as DB[DB Number].[DBB][Address].

[M]

MB [Byte address]

Word addresses

Enter W to the device type. (MW, QW, IW, PIW, CW, TW, DB1~65535.DBW )

Then enter the address in word unit. (Always the multiple of 2)

 

[DB]

DB is formatted as DB[DB Number].[DBW][Address].

[M]

MW [Word address]

DWord addresses

Enter D to the device type. (MD, QD, ID, PID, CD, TD, DB1~65535.DBD )

Then enter the address in word unit but in the multiple of 4.

 

[DB]
