Appendix A: Supported PLCs

Siemens Energy & Automation, Inc. 59

Note: The V-Memory word numbers in the above

table are shown in octal. These numbers

must be converted to decimal before they

are entered into the DTU3005 Configuration

Software. For example, if the DTU3005 is to

access register V02000, the value 2000 in

octal corresponds to the value 1024 in deci-

mal. The value 1024 is then entered into the

DTU3005 Editor Program.

Device data should be written to the data registers

starting at V02000 octal, or 1024 decimal for the

DTU3005 Editor Program.

A.6 Koyo/PLC Direct/TI 405 Series

PLCs

Registers Accessed

The DTU3005 can access all register types in the 405

Series PLC through the use of the V-Memory assign-

ments shown in the following table:

Note: The V-Memory word numbers in the above

table are shown in octal. These numbers

must be converted to decimal before they

are entered into the DTU3005 Configuration

Software. For example, if the DTU3005 is to

access register V02000, the value 2000 in

octal corresponds to the value 1024 in deci-

mal. The value 1024 is then entered into the

DTU3005 Editor Program.

Device data should be written to the data registers

starting at V01400 octal, or 768 decimal for the

DTU3005 Editor software.

A.7 Koyo/PLC Direct/TI 305 Series

PLCs

Registers Accessed

The DTU3005 will only access registers in the Data

Area of PLC memory (R400–R577 and R700–R777)

which are 8-bit registers. Because the DTU3005 will

only read and write 16-bit values, it will use two con-

secutive 8-bit registers in the 305 Series PLCs to form

a 16-bit value. The first of these consecutive registers

must be located on an even boundary (i.e. R400, R402,

etc.). The low order byte of the 16-bit value is located

in the lowest numbered register and the high order

byte is located in the highest numbered register.

When entering register numbers into the DTU3005

Configuration Software, they must be converted from

octal to decimal. For example, if the DTU3005 is to

access register R400 (and R401), the value 400 in octal

is converted to the value 256 in decimal. This value of

256 is then entered into the DTU3005 Editor Program.

A.8 Mitsubishi FX Series PLCs

Registers Accessed

The DTU3005 will only access registers in the Data

entering register numbers, only the offset into this

area (0-9999) should be entered. For example, to

access register number D1, the value 1 should be

entered. To access register number D9999, the value

9999 should be entered.

RTS Control

The Mitsubishi FX-32 and equivalent PLCs require RTS

to be active when sending to the PLC and inactive

when receiving from the PLC. The DTU3005 can be
