Control.com - Nerds in Control

Hi,

Can any one help me?

We are using curtis make 1310 controllers in master/slave configuration. there is one master and 19 salve on CANopen network but only 4 slaves are communicating with master.

The baud rate is 125KBPS, Cable is unitronics BUS FD CAN cable and distance is 370 mtr.

thanks,

RLT

certainly not enough information to help you. Please first locate if the error is on the physical or the logical side. Are the four nodes located near the master? Is the cabling OK? ...

For the logical problem much more information is needed, for example how are devices configured, e.g. by providing DCF files.

The errors are on physical side. yes, four nodes located near the master, physically. we have checked cabling and found ok.

by disconnecting these four nodes, next four nodes comes in picture and start communicating with master.

these all are happning physically not logically.

Thanks,

Ramesh

Please check all points there:

I have no other idea. if it's really a physical problem at the cabling,
the answer should be there.
