Hello Everyone,
I need some of your help.
I just have a problem now with the KRC4 Controller box. Some background: we are using this KRC4 connected with an Indracontrol l25 PLC through Profinet and it works fine without any problem for already about 1.5 years. And this problem appears recently.
The error is shown in the picture. It appears when I start the KRC4. And what I found strange is, there is not such kind of problem before and it appears like nothing has been changed. More weird is after several times restart both KRC4 and PLC and uncharge the power, it turns to be normal and the error will just disappear by itself. But the next day, when I go back to work and turn the KRC4 and PLC on, this error appears again and I need to restart them several times again to hopefully get rid of it. One month before, it appears like 1 time in a week(assuming that I am using it every day), but now it appears just like an old friend and says "Hello" to us every day.
Thank you in advance.
