Additional Information
CAN bus
The CAN bus can be used to connect two or more controllers with each other or with the data logger to exchange data.
1. The controllers are connected in series with the CAN bus cable.
2. The first and last controllers in this connection in series must be fitted with terminating
resistance.
The wiring of the two CAN sockets is arbitrary.
3. Optionally, the data logger can also be connected to the CAN bus.
Tips
The service values include not only current measurement values and operating states, but also all of the settings for the
controller. Write the service values down just once after commissioning has been successfully completed.
In the event of uncertainty as to the control response or malfunctions the service values are a proven and successful
method for remote diagnosis. Write the service values down at the time that the suspected malfunction occurs. Send the
service value table by fax or e-mail with a brief description of the error to the specialist or manufacturer.
To protect against loss of data, record any statistics and data of particular importance at regular intervals.
