Clock Pulses
Section 4-15
4-15 Clock Pulses
The Clock Pulses are flags that are turned ON and OFF at regular intervals by
the system.
The Clock Pulses are specified with symbols rather than addresses.
Note
The CX-Programmer treats condition flags as global symbols beginning with
P_.
The Clock Pulses are read-only; they cannot be overwritten from instructions
or the CX-Programmer.
The Clock Pulses are cleared at the start of operation.
Using the Clock Pulses
The following example turns CIO 100.00 ON and OFF at 0.5 s intervals.
