according to bit error
rate
Interference display
Number of busy lines
in the 2.4 GHz fre-
quency range
Status: Function
green Operating status OK (independent of radio
communication)
red Disruption of the local internal data bus
connection, the field voltage or the internal
communication (circuit board)
green Connection to master established
green flashing Data transfer
off No master is configured for this slot.
yellow flash- Connection to the master is being estab-
ing lished (in communication mode only)
yellow System is being configured (in configura-
tion mode only) or connection to the mas-
ter could not be established (in communi-
cation mode only)
red Connection interrupted by error (in com-
munication mode only)
green Signal strength of the received signal good
yellow Signal strength of the received signal very
strong (solution: increase distance of the
device)
Red Signal strength of the received signal weak
(solution: reduce distance of the device).
off There is still no information on the signal
strength of the received signal (there is no
connection or there is a connection only
after a few seconds)
green low bit error rate <10
yellow bit error rate 10
red high bit error rate > 10
(bad transmission line)
off no active connection (similar RSSI)
green > 53 lines free (no or negligible third-party
activity in the frequency range)
yellow 39...53 free lines
red < 39 marked as free (massive third-party
activity in the frequency range)
off no active connection (similar RSSI)
