Each ISOnet slave checks the network for an ISOnet master. If there is no mas-
ter available, the display will show the fault message “ISOnet Master?“ after
approximately 1 hour. Additionally, the LED for device errors lights and the
Relay K3 switches. With the ISOnet function activated, the function input
F1/F2 is automatically deactivated.
In comparison to a solution with coupling switches and function input F1/F2,
the response time will be extended because the measurement is not perma-
nently carried out.
All EDS devices in the IT systems being monitored must be
operated with activated fault memory.
