You can enter the operand absolutely or symbolically (using an
assignment list) as shown in the following example:
Absolute representation:
Symbolic representation:
For more information on absolute and symbolic programming, refer to
your STEP 5 manual.
The STEP 5 operation set enables you to do the following:
• • set or reset and combine binary values logically
• • load and transfer values
• • compare values and process them arithmetically
• • specify timer and counter values
• • convert number representations
• • call blocks and execute jumps within a block
and
• • influence program execution
The central bit for controlling the program is the result of logic
operation RLO. This is obtained as a result of binary logic operations
and is influenced by some operations.
Section 3.5 describes the whole STEP 5 operation set and explains how
the RLO is obtained. This section also includes programming examples
for individual STEP 5 operations.
