The Clock Pulses are specified with labels (or symbols) rather than
addresses.
Specify the flags as shown above using the CX-Programmer or Programming
Console.
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 Programming Devices.
The Clock Pulses are cleared at the start of operation.
The following example turns CIO 000000 ON and OFF at 0.5 s intervals.

Note The clock pulses cannot be designated directly in programming or allocations
inside C200H Special I/O Units.
Clock pulses are updated during program execution, so the ON and OFF sta-
tus may differ at the beginning and end of the program.
