14 Trouble-Shooting

14.1 Network optimization

Once the WirelessHART network is running, there are some simple measures that will help to

enhance network performance and reliability. These measures are described in the following.

NOTE!

• After installation and configuration of the network, give it a couple of hours to stabilize itself,

before taking the following steps.

14.1.1 Verify Connections

Check that each device has joined the network and is communicating properly. If you cannot

establish a connection to a device, the device is probably too far away or an obstacle blocks the radio

waves. In this case, add an additional device to bridge the gap.

14.1.2 Eliminate Bottlenecks

If the messages of several devices all have to pass through one single device to get to the gateway,

the network has a bottleneck. If the device at the bottleneck fails, whole parts of the network get

cut off from communication because there are no alternative paths to route messages.

To eliminate bottlenecks in a wireless network, add at least one device near the bottleneck to

provide redundant communication paths. There should always be at least two communication

devices in each signal path.
