Function Explanation
1.
EQ is used for an equal comparison of two or more variables and constants. If
In1
=
In2
=
…
=
InN, Out
is TRUE
.
Otherwise,
Out
is FALSE.
2.
The input parameters
In1~InN
are allowed to be the variables of different data types in this
instruction when the data types of input variables are not BOOL, TIME, DATE, TOD and STRING.
When the data type of one input variable is one of BOOL, TIME, DATE, TOD and STRING, input
parameters In1~InN are all required to be of the data type. For example, if the data type of In1 is
TIME, the data type of In2~InN must be TIME. Otherwise, an error will occur in the compiling of the
software.
