  • Page 29: Parameters Of The Channels

    Parameters/address space 5.2 Description of parameters Function: You can specify the discrepancy time for each channel pair. Behavior while discrepancy time is running: While the configured discrepancy time is running inside the module, the affected input channels supply either the last valid value or "0" to the safety program in the F-CPU, depending on the configured discrepancy behavior.
  • Page 30 Due to physical properties, crosstalk of signals can occur on longer unshielded signal wires (see section "Electromagnetic compatibility" in system manual Distributed I/O System ET 200SP HA (https://support.industry.siemens.com/cs/ww/en/view/109761547)).
