The example shows a successful log of a loop with 18 devices addressed as 21 to 38. The letter ‘L’ only
appears when a device is first logged. Once the loop as been logged and the new devices saved,
subsequent logging has the prefix ‘R’.
The following example demonstrates the usefulness of this display:
In the example addresses 21 to 28 are connected to Line 2 and 29 to 38 are connected to Line 1.
Addresses 32 and 33 have been added since the last log.
This information shows a line break, but the break is not necessarily between addresses 28 and 29
unless it can be confirmed that the devices are wired sequentially around the loop.
X - at address 35 could also indicate a double address or the device has gone missing since the last
log.
