Description
Set the number of steps of the cam switch. A step
indicates the point in which the Low state is switched
to the High state or the High state is switched to the
Low state. The valid Step No. is determined
according to the set value of "Number of Step".
The value set with "Lower Limit" in the counter timer
block is applied.
Change the setting value in the counter timer block.
Set the initial state of output. When "Count Value" of
the counter timer block is less than the input value of
"Step No.0", the output status turns to the initial state.
The output status of "Step No.0" or later inverts to the
High state or the Low state for every step No.
Compares the values of step numbers with "Count
Value" in the counter timer block. When "Count
Value" is equal to or larger than the input value, the
previous status is inverted.
The value set with "Upper Limit" in the counter timer
block is applied.
Change the setting value in the counter timer block.
Description
Only even addresses can be assigned to the
parameters of two words (32 bits).
