Sensors with digiLine electronics
A digiLine electronics assembly that was disconnected from the bus for mainte-
nance and repair is detected again automatically upon reconnection, linked to
its original assignment table entry and resumes operation.
When replacing JUMO digiLine electronics assemblies, each electronics as-
sembly must be replaced individually before the next one is disconnected from
the bus. In this way, each new digiLine electronics assembly is linked automat-
ically with the original assignment table entry.
Digital sensors from the product groups 2026xx
A digital sensor from the product groups 2026xx that was disconnected from the
bus for maintenance and repair is detected again automatically upon reconnec-
tion, linked to its original assignment table entry and resumes operation.
When replacing digital sensors from the product groups 2026xx, it is necessary
to follow the initial startup procedure to put the new digital sensors into operation
(see Chapter 7.2.1 "Initial startup", page 68).
6 Check whether the assignment table entry has changed from "In-
stallation" to "linked". If this is not the case after a waiting period of
about 10 seconds, linking has failed. In such a case, check the cor-
rectness of the configuration and bus cabling (see Chapter 24.1
"Troubleshooting and remedies for digital sensors", page 383). For
diagnosis, it is helpful to display more information about the assign-
ment table entry. To display the information, press the "Info" but-
ton. This opens a text window in which, among other things, the
most recent bus fault is displayed.
