  To troubleshoot a lack of communication with your Lenze Network Hardware controller, begin by ensuring the controller is receiving power, consulting the operating instructions for the basic unit. Confirm the fieldbus module's voltage supply: check the connection if supplied by the basic unit, or verify 24 V voltage (plus 10%) at terminals 39 and 59 if externally supplied. Also, check the connection to the controller and make sure that the addresses are identical. Ensure the controller address is unique for all connected devices. Check the wiring to your host. If the controller does not receive telegrams, check whether the connection corresponds to the instructions given in chapter 'CAN bus wiring', page. 4-1. Check whether host sends telegrams and uses the appropriate interface.
