Diagnostics Via Io-Link - Siemens 3RS2 Manual

Digital devices with IO-Link
6.10 Diagnostics via IO‑Link
The block supports you in the following tasks:
• Parameter assignment of the monitoring relay for IO-Link during operation
• Executing IO‑Link port functions
• Backing up/restoring IO-Link device parameters
• Backing up/restoring IO-Link master parameters
Use of the IO-Link Call function block FB1
• Install the demo project "IOL-CALL". You can obtain the demo project on the Internet
support.automation.siemens.com/WW/view/en/33102519/133100).
• Copy the IO-Link Call function block FB1 (including data block DB10) to a STEP 7 project.
• Use the IO-Link Call function block FB1 as described in the demo project.
6.10 Diagnostics via IO‑Link
Temperature monitoring relays for IO‑Link also support diagnostics via IO‑Link in addition to
diagnostics via LEDs and via the display.
The manufacturer-specific diagnostics listed in the table are reported via the diagnostic
mechanism of IO‑Link. The table below provides information on possible causes and remedial
measures:
Table 6-1 Diagnostics via IO‑Link - possible causes and remedial measures
Diagnostics and messages
Invalid parameter
Self-test error / internal error
Limit for overshoot exceeded
Limit for undershoot violated
Temperature sensor 1, 2, or 3 - meas‐
uring range overshoot
Temperature sensor 1, 2, or 3 - wire
break
Temperature sensor 1, 2, or 3 - short-
circuit
60
Possible cause
The set parameter is invalid.
Fault in internal test.
The temperature set is higher than the lim‐
it value set for overshoot.
The temperature set is lower than the limit
value set for undershoot.
The temperature is outside the permissible
temperature range of the temperature sen‐
sor used.
• The cable to the temperature sensor
has a short-circuit.
• The temperature sensor is defective.
• The connection to the temperature
sensor has been interrupted.
• The temperature sensor is defective.
Possible remedial measure
Specify a parameter in accordance with
the parameter table in Chapter ... .
Return the device to the manufacturer.
• Reduce the temperature.
• Set a higher limit.
• Increase the temperature.
• Set a lower limit.
Install and configure a suitable tempera‐
ture sensor.
• Check the connection to the temper‐
ature sensor.
• Use a new temperature sensor.
• Check the connection to the temper‐
ature sensor.
• Use a new temperature sensor.
