Ethernet indicators
RJ-45 connection sockets on instruments with a EtherCAT® or PROFINET interface have two integrated LED indicators, with
standard Ethernet functionality:
Amber: Ethernet speed
Green: Ethernet link/activity
The tables below list the different LED indications:
•
Green

continuous
Power-off or program not running
on
continuous
Normal operation mode
short flash
0.1 sec on,
2 sec off
Valve Safe State mode; there is no bus communication (PROFIBUS DP, DeviceNet™,
EtherCAT® and PROFINET). Valves are in safe state. This LED indication is also active
when the instrument is in ‘Initialization Mode' (parameter
Init Reset
= 73)
blink
0.2 sec on,
0.2 sec off
Special function mode; the instrument is busy performing a special function (e.g.
auto-zero or self-test)
