7.1Fieldbus communication error diagnostics

Connections for fieldbus mode If the product cannot be addressed via the fieldbus, first check the connections. The product manual contains the technical data of the device and information on network and device installation. Check the following:

•24Vdc power supply

•Power connections to the device

•Fieldbus cable and fieldbus wiring

You can also use the commissioning software for troubleshooting.

Fieldbus function test If the connections are correct, check the settings for the fieldbus addresses. After correct configuration of the transmission data, test fieldbus mode.

▶In addition to the master, activate a bus monitor that, as a passive device, displays messages.

▶Switch the supply voltage off and on.

▶Observe the network messages that are generated briefly after the supply voltage is switched on. A bus monitor can be used to record the elapsed time between messages and the relevant information in the messages.

Addressing, parameterization If it is impossible to connect to a device, check the following:

▶Addressing

Each network device must have a unique IP address.
