Hello,

i am having problem with DP/DP copuler. I can not cofigured that I wont have any errors (look pictures).

Do anyone have any idea what I am doing wrong?

Thank you.

Hrello dado;

All ypur LEDs are active for connection side #2, SF  is active on connection side #1. There are probably many errors you have to check in your configuration.

- first, check whether the addresses you set on the DIPswitches are valid, they must match your Profibus slave configuration. Right now, slave 1 is at adderss 12, slave 2 is at address 3.

- second, your DIA switch is set on each side, do you really want the complete diagnostics fr the module? Read the notice in the attachment below.

- third, explaon how you have setup the data exchange zones on each side of the slave. Note that they have to be inverted but in the same order and size:

on side 1, for example, 8 Bytes OUT, 16 Bytes IN

on side 2, (reversed), 8 Bytes IN, 16 Bytes OUT

You will find all required details in the DP/DP coupler manual:

I kind of sort problem out... now I have problem that  comunication si falling down (for a few seconds and then after few second came back)- BF1 lights red and BF2 (my side) is flashing very fast .
I am conected to DP2 and if I disconect DP conector on DP1 then comunication is OK.

Anyone had that problem? How to soved?

Thanks in advance,

Hello;

The flashing LEDs indicate you have no connection from the DP masters (on both sides) with the DP/DP coupler. See the attachment from the manual suggested earlier (you could have at least opened the diagnostics chapter...).

In any case, there are a few suggestions in the LED description, I would add that you should open the diagnostic buffer of both DP-masters and see what they detect as the source of the fault.

Hope this helps,
