Advant 450 profibus communication problem
Hi,
I have problem with profibus on one of our Advant 450 controller (profibus card is CI541V1). Below you find alarm list for this issue.

On this specific bus I have only 2 nodes (2 Pfister weightfeeders) and I loose communication with both of them. What is more I have used Profitrace analyzer and every parameters of the bus are ok (regards specification) + no problem with termination of the bus. What is more it has been working for 5 years with no problem.
Do you have any idea what mau cause the problem?

I did this procedure several times!
Yes, it is right, that you don't need to power down the AC450 Controller when you want to replace the CI541V1 Board. Unfortunatelly, this CI541V1 is one of those very rare boards, which cannot be plugged in or pulled out of the SC5x0 directly, so you have to do the procedure as described!
On the other hand you need to check, if there is another board on the same SC5x0 where the CI541V1 is located. Because when you pull out the SC5x0, then of course both boards located in that SC5x0 will not work!

Hi,
I guess Station 10 and 11 are the Pfister weightfeeders and the Profibusline has Bus Number 6, isn't it?
I would try to restart the CI541V1 board!
Maybe you can also try to use a Spare CI541V1
What are the Status LEDs on CI541V1 showing?
What is the DB Element of the CI541V1 showing (Output Terminals)

I have got one more question:
"In Advant Controller 450 you first have to unplug the submodule carrier (SC510
or SC520). After that you can insert the CI541V1 into this submodule carrier and
finally plug in the submodule carrier again. This means that you do not have to
power off the whole Advant Controller 450."
Above is quotation from 3BSE 016 040R101 Rev B.
Did anybody do it before? I mean replacement of CI541V1 wihout turning off power supply for PLC, only by unpluging submodule carrier?
