Influence on
PC Scan Time
Mounting one Position Control Unit on a PC extends the PC’s scan time by
about 3 ms. In addition, when transferring data, the scan time during which
data is transferred increases by another 5 ms. For example, to transfer all 20
positioning actions, TRANSFER DATA only needs to be executed once, but
both the PC and Position Control Unit require 3 scans. Each of these 3 scan
times will be 5 ms longer than the normal scan time.
