3.2.2.7 MUX
Various constants or variables can be selected by means of an index which is located in front of the
command in the accumulator. The first value is accessed via Index 0. The selected value is loaded into the
accumulator. The number of values is only limited by the program memory.
BOOL BYTE INT DINT
Possible data types X X X
Commands Explanation
LD 1 Select the required element
MUX 10,20,30,40,Value1 MUX command with 4 constants and one variable
ST Value2 Save the value 20 in Value2
Table 17 MUX
3.2.2.8 MOD and MOD(
The accumulator is divided by one or more variables or constants. The remainder from the division stands in
the accumulator as the result.
For bracket Modulus, the accumulator is divided by the result of the expression in the brackets and the
modulus is formed from this. Up to 6 bracket levels are possible.
BOOL BYTE INT DINT
Possible data types X X X
Commands Explanation
LD 25 Load the dividends
MOD 20 Division 25/20

Modulus = 5
ST Var1 Save the result 5 in Var1
LD 25 Load the dividends
MOD( Var1 Result = 25/(Var1 + 10)

Modulus in the accumulator
ADD 10
)
ST Var3 Save the result 10 in Var3
