Intelligent Power Supply KNX PS640-IP 2U
• Version: 21.09.2021 • Technical changes and errors excepted.
load, load disconnection, device startup and KNX bus reset are easily accessible. The
data can be read out via the KNX bus. It can be sent on demand, periodically and after
a certain change in value. It can also be sent after an error event and on crossing a pre-
set threshold value. Number and duration of such over-threshold events are also avail-
able information. When the device returns to normal working condition (after KNX bus
reset, device startup, short circuit) info telegrams are sent automatically. Additionally,
extensive alarm and maximum tracking functionalities are available.
In this document, physically addressed telegrams are named Physical Telegrams.
In this document, group oriented telegrams are named Group Telegrams.
