6.8.4.4 Input Syntax
The following figure illustrates the structure of the input syntax for vari-
ables in the programming software.
Fig. 6-173: Syntax diagram
Variable addresses written with a comma are decoded as follows:
Variable address = Figure 1 (high-byte) x 25610 + figure 2 (low-byte)
You can enter figure 1 and figure 2 as a decimal or hexadecimal, but
you must use each to the same base (for example, DW16,16 or
DWh10,h10).
Variable Number
The MMICOM profile is used to assign the data on a controller-inde-
pendent basis, based on a variable number. A fixed controller address
is only assigned to a variable number in the controller (for example, the
variable number 50 will be assigned to the flag 32.0). The variable
number can either be entered as a decimal (without an ID) or as a
hexadecimal (with a leading h).

Number
A linear, ascending variable number area must be reserved for data
structures greater than 4 bytes (for example, alphanumeric texts, tables,
polling area, status messages). This number area must be determined
by the size of the data structure and the access used in each case.
When you start up the operating device, a one-byte read access is car-
ried out on the variable with the number zero. In this context, the data
read is not interpreted, and the read function block does not have to de-
code this variable number.
