Hello, I have an ethercat slave device which i want to restart, since in some conditions i have failure, and I would like to restablish it to normal operation. I tried the command FB_EcSetSlaveState and I get the error: "target port not found" "possible causes: ADS Server not started" How do I know about the ADS Server? Any hint would be a great help

sNetId: This is a string that contains the AMS network identifier of the EtherCAT master device.

nSlaveAddr: Fixed address of the EtherCAT slave whose state is to be set.

Both information you will find in the system manager under the EtherCAT Device.

Dear Neals, Thanks for the collaboration. Off course I checked the Infosys and tested the results prior to writing my doubt in this forum. I will give you more details on how i used this Function Block. Do you know any other way to deal with a Klemme when there's an error? maybe reseting it this way is not the best solution. on the sNetID, i just left a blank string ('') since the run-time is located in the target PLC. Just in case, i have also used the NetID obtained from the AMS Router. The PLC is a CX8090 with a EL2008 and a EL6751 connected The slave address, i obtained it in the System Manager at I/O Devices0=> Gerät 2 (EtherCAT => Klemme 1 (EK1200) => EL6751 => EtherCAT tab => EtherCAT Addr. Is this configuration the right one?

Keeping a blank NetID wouldn't work, because the EtherCAT Master has normally a NetID with *.*.*.*.2.1 and blank one meens the loopback to 127.0.0.1.1.1

Neals, it worked! I wasn't sure about the addressing, and i was using the PLC run time address instead of the EtherCAT Master Address. (under I/O Devices0=> Gerät 2 (EtherCAT)) which was actually *.*.*.*.3.1 All this is very confusing. Anyway, i managed to restart my slave. Thanks The question now goes this way: As I said before, i am using a EL6751 (CanOpen Master, which sometimes detects an error and stops receiving due to a problem in a CanOpen device, i still dont know how to solve that), but in the mean time, i am just trying to reset the Klemme as an autorecover feature. There's no a better way to react when a slave is in some error state? Thanks again

For diagnostics you can map the node state and device state into the PLC.
To reset the CANopen Master there is a device reset available.

This instruction was more useful than the other one. In this case, i used the empty for the NETID string and the DEVICEID assigned by the System Manager (an integer number) I hope this is useful for other people searching for the same
