610 System Functions
You define and select SLC M1 Integers using the Tag Explorer (under
SLC M1 Integer) and the Tag Window. It is not necessary to use the
Indirect SLC M1 Integer Variable function to specify them directly.
Syntax:
Indirect_SLC_M1_Integer_variable[variable number]
Insert a value or expression equal to the desired variable number. The
argument is evaluated as an integer, and must have a value from 0 to 511.
RIO Adapter Variable
Use the RIO_adapter_variable function to specify RIO adapter formatted
data input groups directly in an expression.
You define and select RIO adapter inputs using the Tag Explorer (under
RIO Formatted Input) and the Tag Window. It is not necessary to use the
RIO Adapter Variable function to specify them directly.
Syntax:
RIO_adapter_variable[address, type, scale factor]
See Using the RIO Adapter Option chapter for more details.
Argument Description
Address The beginning address: 4, 20, 36 or 68.
Type One of the following numerical values:
0:Formatted Binary
1:Formatted BCD
Scale factor If you use the scale factor, the controller will multiply this number
against the value read from the PLC output image table.
If you do not use scale formatted data when defining this variable,
the value of the formatted data input group equals the value read
from the PLC output image table (effectively using a scale factor of
1).
