Understanding the Features
3--13
Let’s examine the different address conventions for
Direct
LOGIC and
Allen-Bradley. For example, the
Direct
LOGIC address references are
octal
, and
the
Allen-Bradley
is
decimal
.
The
Direct
LOGIC
DL05/DL105/
DL205/D3--350/DL405 OP-panel address uses V-memory registers which are
16-bit registers. The DL305 family uses reference assignments with 8-bit registers.
This means that the DL305 will require twenty-four 8 bit registers for data handling.
The Allen-Bradley memory is defined with a reference
(Nx)
which represents the
memory area and
(:n)
which defines the word within the memory area. Please refer
to the appropriate CPU User manual for the PLC product you are using.
