Thanks Leg
Motherboard is V7 - all capacitors look good.
No problem
have you any bus cables you can swap over its a strange fault !

The multi tap doesn't need any drivers or configuration, it's just a way of connecting several devicenet plugs, it's got a 24v power connection and if you look all the of the CAN lines are joined. One of the leads should go up to the MFC.
Hi Eusty, quick question: is it possible to connect multiple devicenet nodes on each multi-tap A30 connector in a daisy chain config? or should I connect only 1 node per output?
In my case, I have a beckoff IO module in X943.3, a FESTO pneumatic valve isle in X943.2 working fine. And I want to add a WAGO IO module in X943.2.
Is taht possible? I´m having an "error reading DevNet driver", or smth like that. Is it possible that a 20m drop line to the FESTO isle is causing some troubles?
Thanks again!!
X941 - 24vdc
X942 - Diagnostic connector
X943.1 - MFC or LPDN
X943.2 - Branch 1
X943.3 - Branch 2
You can connect multiple nodes to any branch.
Although there are rules about the branch and drop lines I've never had an issue, although 20m for a drop is a bit extreme. Remember the terminating resistor needs on the branch needs to be longer than the length of the drop, if you understand what I mean. I would doubt if that's the issue though, more likely a configuration problem?
As a general rule of thumb, find the two points furthest apart (in cable length) on the DeviceNet bus and place your terminating resistors there. It's a bit strange to get used to, but the "trunk" is defined by the placement of the resistors, not by the physical branches of the cable.
imho that is just chasing your own tail - trying to get DeviceNet working before you got robot to boot up without error messages.
But if you insist here you go:
what is the total length of all devicenet cables in a network, and if you are using drops what is the cumulative length of all drops? what is the baud rate?
there are limits:
125kbps: total bus length max 500m, total drop length max 125m
250kbps: total bus length max 200m, total drop length max 78m
500kbps: total bus length max 100m, total drop length max 38m
max drop length is only 6m, and this is IF you are using proper thick DeviceNet cable for a trunk (drop may be thin DeviceNet cable).
Hi Everyone. Just to assist future members of this forum, our original problem is now fixed and the robot is operational. In the end I had to change the hard drive and reload KSS. Somehow the original owner had a 320GB drive in the unit(and I assume operational) but I could only get the unit to accept a 80GB then 120GB drive to get around the XP limit on drive size. Then with this smaller drive and a reload of KSS (from new disks) all is good.
Thank you for everyone's advise to solve this problem.
thank you for posting feedback, that is the best way to close a topic...
