[...] Hello, thank you very much for your answer. I 'm sorry, but I don't know what is the SFRT :( I mean, I just know that if the connection is good between the remote control and the PLC, and that en emergency stop is pushed, i need to stop immediatly. But, also, I don't have to stop the machine ...

[...] Hello Christian, Thank you for your answer ,but I didn't see it, sorry. I understand in your message that it could be possile for your understanding. I am just setting up a moke up to test it, but it seems that I am limited to 1,92s with the PROFINET layer. I mean, in the Real Time settings o...

Hello PROFINET experts :) , I am working on an architecture on which i need to send an Emergency Stop Signal throught a Black Chanel communication system (trought antenna). On the machine side, I have a SIEMENS PLC (S71500 family), which activate the power of the machine. On the other side, I have ...

Can someone provide a comprehensive list of all of the vendors providing PROFIsafe master/controller software stacks? Please :) . Unfortunately, such a "comprehensive" list does not exist and would be rather small, and you will need to invest your own time to investigate whether the provi...

Could you please provide guidance on if the following feature --- PROFIsafe Parameterization in Run (PiR) --- is a mandatory feature for a device certification according to the PROFIsafe V2.6 MU1 / PROFIsafe V2.6 MU2? No, PiR is not a mandatory, but an optional feature. All new features described i...

The PROFIsafe Profile states in section 'Adjustment of watchdog times for FSCP 3/1': It is highly recommended that the difference between the assigned parameter value F_WD_Time and the sum (DAT, HAT, and bus transmission delays) does not exceed 30 %. Why is this the case? In section 'Calculation an...

The PROFIsafe Profile states in section 'Adjustment of watchdog times for FSCP 3/1':

It is highly recommended that the difference between the assigned parameter value F_WD_Time and the sum (DAT, HAT, and bus transmission delays) does not exceed 30 %.

Why is this the case?

The "FSCP Test Mode" is mentioned several times in the PROFIsafe specification, but it is not defined explicitly.

(from PSDW 2023) Is there any license condition on the PROFIsafe Layer Tester? E.g. can it be distributed freely internally in a company ,once it has been purchased by this company or is this restricted to this department/division, which order the Layer Tester? The layer tester may be used freely w...

Question from the PROFIsafe Designer Workshop in October 2023: Does there exist a "safe router" which can bundle and redistribute safety data? This could be used to, e.g., distribute safety data from one safety function (consisting of senor/logic/actuator) to additionally affected actuato...

Questions from the PROFIsafe Designer Workshop in October 2023: As long as there is no security in the safe fieldbus protocol, the only solution security-wise is to isolate the devices in the network.
