@zesoo C:\Windows\System32\icsneo40.dll is the typical location. You can right click on it and go to properties to grab the version information.

@zesoo Thank you, I'm looking at it now to see if I can reproduce it.

@zesoo I can't reproduce this here but it looks like its crashing due to use of ExtraDataPtr (It shouldn't). Whatever Message #416 is, is creating the crash.

Can you change line 115 that reads this:

data = m.Data if not m.ExtraDataPtr else m.ExtraDataPtr

to this:

data = m.Data if not m.ExtraDataPtrEnabled else m.ExtraDataPtr

please and report back?

@drebbe-intrepid Thanks a lot,it worked,I wondering how to get the exact timestamp of the message.

 timeHw=m.TimeHardware|m.TimeHardware2<<32
 timeSys=m.TimeSystem|m.TimeSystem2<<32

HI:
I use the API get_timestamp_for_msg to get timestamp,

ts=ics.get_timestamp_for_msg(device,m)

but the result was 37 years off from the actual value.

@zesoo sorry for the late reply, ValueCAN4-2 doesn't have a battery for the RTC so you need to set the RTC when you open. See https://python-ics.readthedocs.io/en/master/index.html#ics.ics.set_rtc
