I am using KRC 4 2014. Version KSS 8.3.7. The robot Kuka KR 6-2 was already in production, it was bought, brought and of course
everything broke. The password was changed by Kuka, lost, and so on. I had to reinstall KSS, then write a project on WorkVisual 5.0, etc.
After these manipulations, the robot started working and there were no errors. The next step was to connect the welding machine using DeviceNet(pinout shown in the photo, terminator 108 ohms)
Kemppi 450 Pulse.(to understand the situation in the old project, the welding machine was a slave). For communication, I use the BeckHoff EK1100 + EL6752 modules. The EK1100 module is powered by a security board (which was still allowed in the 2014 versions, pinout in the photo (brown wires do not look they are not used))
A project was written with these modules, the ArcTechBasic 1.2.1 cop files and the ArcPulse EN welding machine settings, macids were set (Kuka Master ID=1, Kemppi Slave MacID=3), mapping was made (also specified in the attachment).
Installed in the controller Asteca 1.2.1, loaded the project. And I got errors that can be seen from the photo of the control panel. I checked the voltage at the input to the board
installed in the welding machine, got 0V. The EL6752 module itself hangs in an error (incorrect MacID or voltage error), but I rechecked everything correctly
(the switch in the welding machine is set to MacID=3, speed=500). Hence, only the tension remains.
(I tried to re-upload the projects from the source one, downloaded them from the controller again, and rebuilt the project in WorkVisual, too, did not help)
I tried to replace the wire itself from DeviceNet (I rang it) just in case, it also did not give results. The EK1100 module itself signals that it has received 24V and transmitted 24V
over the connection bus. But after EL6752, the signal is processed.
Tell me what else I can check, maybe you will see my errors and so on? Maybe i can reset this module, or reset EL6752 connection with BeckHoff EK110
