12.4 Specifying the AutoMax PC3000 CPU
Tick Rate
AutoMax programs can be executed at a fixed scan rate. The scan
rate is specified in terms of ticks."
The AutoMax PC3000 has a programmable tick rate, meaning you
can change the definition of a tick. By changing the tick, you change
the time base for program execution and, therefore, the program's
scan rate. The default setting for a tick is 5.5 ms. You can set the tick
rate in increments of 0.5 ms.
You define the tick rate for a Processor offline. It is not set until you
load the configuration to the Processor.
To set the tick rate for an AutoMax PC3000 Processor, do the
following:
Step 1.

tick rate you want to change.

Step 5. Generate a configuration.
Step 6. Load the configuration to the PC3000.
