SYSTEM DESIGN The BA614DF Indicator is powered and communicates via the fieldbus which is connected to non-polarised terminals 1 and 2. As shown in Fig 1 the instrument may be connected to any fieldbus segment which can supply the additional It is available in different variants. In the standard variant, CC-Link is a fieldbus system enabling a data transfer rate of up to 10 Mbit/s over a total cable length of 100 m, as well as real-time communication with up to 64 devices in the network.

Look at page 212, extract as attachment below. This seems to indicate that the Profinet interface card on the drive is not installed or parameterized properly. After a couple of minutes without communications, you will get "Fieldbus Fault W34", a comm failure on the card. It has no effect on the operation of the VFD, but if you want it to go away you can do one of 3 things: 1. Connect your bacnet comm (with some bacnet traffic). 2.

Important User Information Solid-state equipment has operational characteristics differing from those of electromechanical equipment. Fieldbus is simply a means of communicating with input devices (sensors, switches, etc.) and output devices (valves, drives, indication lamps etc.) without the need to connect each individual device back to the controller (PLC, Industrial PC etc.). Therefore, overall, Fieldbus can reduce costs.
