Thank you for your response!
I misspelled and meant "read or write request".
For example, the IO Device sees the following sequence and reacts as expected:
1. Connect request from host
2. Connect response from device (CMI timer starts)
3. Write request from host (CMI timer stops)
4. Write ...

The IEC CD 61158-6-10 (PN-AL-protocol) defines a CMInitiatorActivityTimeout handled by the IO device.
I'm curious when this timer is started and stopped. I can find a description with state machine in chapter 5.6.3.8 for the CMSM.

The CMSM switches from state IDLE to state RUN when CMDEV is ...

"Object lldpXPnoLocPortOperMauTypeExtension of invalid type. Expected Gauge32, received Integer32."


On first look it appears your implementation is correct and the test is wrong.
I suggest to contact your vendor (? stack supplier), they should have the possibility to solve or address the ...

Hello,
Having Windows User interface capable in reading TCP/IP, UDP, serial etc messages but now customer say "having data string using profinet protocol". Do you need some Profinet interface card installed in PC for this? And/or some dll to read data string as TCP/IP?


I find it difficult to ...

Is the implementation of the I&M4 data record optional? The signatures/CRC in I&M4 are usable only for the safety parameterization or also for the complete device parameter set (also non safety parametersets)?


Supporting of IuM4 is optional by a device. If a device supports PROFIsafe profile it ...

Hello. This is my first post.
I have some experience with PROFINET testing. I have a problem. We have two X005 SCALANCES, the part number recommended for the Netload test.
One of the switches works as expected. But the other does not work as expected. I explain myself: The standard setup for ...

We have in field unexpected alarms with different devices. Some devices send in case of using FSU very often after a power cycle an alarm "Port data change notification - line delay mismatch". After few milliseconds the alarm disappers. We see this only by some devices and we think it differs in ...

The application classes 1, 2 and 3 (out of the 6) can be realized with RT.

Thank you. One additional question:
What are the drawbacks or constraints of using a software-based Profinet solution ?​


You are welcome.
Drawbacks are:
- no IRT communication is possible
- additional switch/PHY is required


In general software based solutions do not support some of the ...

What hardware-based Profinet solutions are currently available in the market ?​



There is plenty of hardware supporting the PROFINET, which one fits for you depends on your requirements (desired features, integration needs..). The range spanns from standard ethernet controller up to full ...
