In ETS Test Setup, the PROFIsafe tests are sometimes successful, sometimes failed (if repeated without changing anything). The failure is due to PROFIsafe watchdog expiration. What could be the reason for this instable behavior? Without having further details, it might be due to an F_WD_Time settin...

Hello, we created a device that implements several PROFIsafe submodules. These submodules are combined in one PROFIsafe module using the attributes "PhysicalSubslots" and "FixedInSubslots" Example: <ModuleList> <ModuleItem ID="IDM_1" ModuleIdentNumber="0x00000001&...

Hello, We have a drive connected to a PC equipped with CP1616 and Spirta. We bought the CP1616 to test the drive before going to a PROFINET lab and try the certification (RT and IRT). I was expecting Spirta to establish a synchronous communication with the drive (for example in test Syncslave01_WFU...

Hello everyone, in which cases are the tests with P2P-Setup mandatory? Are these testcases required for certification with 2 or more port devices? (Especially "Different Access Ways P2P" because in list of test specification these test is not listed (Pn-Spec 2021)) Thanks for your answers...

Hello everyone, if have a simple question. Did the test fail in Faulty and Normal mode if one of the two output bits "Qx_Error.." is set? I ran the test with a new device and after the test the device works fine, but the error bits were set in Faulty Mode. (Test was executed with specific...

Hello, I need a helping hand concerning above mentioned test. My device is failing when I run AR-ASE S2 test, in the beginning of Scenario 1-4. Behavior 8, 9, 10 and 11, right in the sequence, are failing as well. AR-ASE and other behavior tests are ok. Log shows the following messages: 14:40:11 - ...

Hey Daniel, thank you for your answer! How are the wd_min and wd_max values measured in detail? Is the watchdog started and then monitored cyclically to determine whether it has been triggered? (wd_max) And how is the wd_min value measured? Thank you very much in advance for your answer! Hi Booster...

Hi Booster, no these are two different Times. The Device-Cycle-Time is the cycle time the time the device communicates with the F-Host e.g. 1ms. The Device-Acknowledgment-Time is the time the device needs to react on a changed MonitoringNumber (MNR). There is no other time included such as transmis...

The PROFIsafe Tests include tests with the Safetylayer-Tester. In documentation of Safetylayer-Tester, the watchdog test is required for certification. It should be checked whether the measured times are within tolerance. Maximum value = ((watchdog value + 10%) + device cycle time + inaccuracy of m...

Hi Forum, My task: I am supposed to filter incoming/outgoing Profinet and Profisafe messages from a safety PLC (probably SIEMENS 15xx series) in a so-called "APL module" and incorporate them into a new frame. The black channel comes to the APL module via Ethernet APL and should now be for...

In general a PROFINET Certificate is valid for three years.

What modifications to an already certified Profinet device are permitted without necessitating the recertification process again ? If the modifications have no influence to the communication a recertification is not necessary. But you need extend your certificate to the new Software Version via a v...
