Customer-Specific Io-Link; Settings; Configuring A Customer-Specific Switch Point With Configuration Of A Switching Delay And Switchback Delay - Endress+Hauser Liquiphant FTL31 IO-Link Operating Instructions Manual

Customer-specific IO-Link settings
IO-Link communication
• Commissioning with factory settings: The device is configured for use with water-based
media. The device can be commissioned directly when used with water-based media.
Factory setting: Output 1 and output 2 are configured for XOR operation.
• Commissioning with customer-specific settings: The device can be configured differently to
the factory settings via IO-Link. Select "User" in the Active switchpoints parameter.
• Each change must be confirmed with Enter to ensure that the value is accepted.
• Incorrect switching is suppressed by adjusting the settings in the switching delay/
switchback delay (Switching delay time/Switchback delay time parameters).
11 Customer-specific IO-Link settings
11.1 Configuring a customer-specific switch point with configuration
of a switching delay and switchback delay:
11.1.1 Switch point
1. Completely immerse sensor (tuning fork) in the medium.
2. Under "Process Data" --> "Forkfrequency", observe the oscillation frequency (as %). (Make
a note of the value if necessary.)
3. Parameter --> Active switchpoints (OU1/OU2) --> "User"
4. Parameter --> Switch point value, Output 1/2 (SP1/2/FH1/2) and Switchback point
value (rP1/2/FL1/2) to configure the switch point hysteresis.
11.1.2 Switching delay and switchback delay
1. Parameter --> Switching delay time, Out 1/2 (dS1/2), parameter for switching delay.
Enter value in seconds.
2. Parameter --> Switchback delay time, Out 1/2 (dR1/2), enter parameter for switchback
delay.
All entries must be confirmed with Enter.
• Block write mode: All modified parameters are written into the device using the
Download function.
• Direct write mode: After confirming a parameter with the Enter key, the parameter is
written directly into the device
