You can choose between
• manual clocking (default)

Manual clocking
You simulate the IP 265 clock pulse by pressing the space bar. Each depression of the space bar
simulates an IP 265 cycle (7.8 µs) (single-step mode).
Automatic clocking
You set the simulator cycle via function keys:
Select "Defaults" in the softkey menu by pressing <F6>.
Select "Sim Clock" in the next menu level with <F4>.
A selection window containing the following options is displayed on the monitor:
"Manual clocking" (default)
"Clock pulses/second"
"Seconds/clock pulse"
Move the cursor to the required text line and confirm with <1> or <INSERT>.
Enter the clocking info. Press <F7> "Info" for information on input fields and editing options.
Press <1> or <INSERT> to confirm your entry.
The control system flowchart is returned to the screen. The real time, in µs, and the current IP 265
cycle time are displayed at the upper right in the COM 265 screen form ( Figure 10-1). When
clocking is automatic, real time and cycle time are updated every second.
