A-3 Overhead Sweep Impact Times
This section contains overhead timing information for the PACSystems CPUs. This information can be
used in conjunction with the estimated logic execution time to predict sweep times for the CPUs. The
information in this section is made up of a base sweep time plus sweep impact times for each of the CPU
models. The predicted sweep time is computed by adding the sweep impact time(s), the base sweep, and
the estimated logic execution time.
See sample calculation for estimating sweep times at Sweep Calculations (in µS).
The following components make up the total sweep time:
â–ª Programmer communications sweep impact
â–ª I/O Scan and fault sweep impact
â–ª Ethernet Global Data sweep impact
â–ª Intelligent Option Module (LAN modules) sweep impact
â–ª I/O interrupt performance and sweep impact
â–ª Timed interrupt performance and sweep impact
