Hi, Send the diagnostic Buffer content, further information within the diagnostic buffer can help you to solve the problem. The replaced card IM153-1 must be the same as the old one otherwise the Hardware Configuration shall be reload with the new configuration. Also you can check the switch of the profibus cable in case the switch is on the resistor position then the bus is cut off. Regards |
