10.1.3 Generating Simulator Settings

Prior to off-line simulation of the IP 265 user program, you must specify the simulator settings.
COM 265 simulator options include:
Looping IP 265 outputs back to IP 265 inputs
Isolating part of the control system flowchart
Specifying actual values via function keys
Specifying signal states
Triggering timer and counter functions
Note
Simulator settings do not immediately affect the control system flowchart. The new signal
states and actual values do not take effect until the next IP 265 clock pulse
( Section 10.1.6).
Looping IP 265 outputs back to IP 265 inputs (<F1> "Loopback")
An IP 265 output can be looped back with a delay to an IP 265 input, e.g. to simulate the function of
a limit switch.
Two delay times, each of which may differ from the other, must be specified for each loopback:
• Delay time for a rising edge at the IP 265 output (signal state change from "0" to "1")
• Delay time for a falling edge at the IP 265 output (signal state change from "1" to "0")
The simulator then loops the edge change back to the IP 265 input after the programmed delay time
has expired.
Note
A looped IP 265 input can be affected interactively via function key <F4> in the
"Simulator" form's softkey menu (
