5. PROFINET operation

5.1. Controller

After having connected the encoder and started the controller (PLC) there is an automated PROFINET boot

up implicating a comprehensive initialising procedure. The device is assigned an IP and the communication

and application structure is built up.

5.2. Operating status indicator (multi-color LED)

The bus cover provides an integrated multi-color LED indicating the encoder's operating status. The LED will

always signal one of the following operating statuses as long as the encoder is live:

Color

LED yellow continuous

LED green continuous

LED red continuous for 2,5 s

LED red flashing slowly (1 Hz)

LED red flashing fast (5 Hz)

At encoder power-on the LED is lit continuously yellow until the PROFINET controller (PLC) has established

the link to the device (encoder). Usually this state is pretty short if the master is already running. However,

this state persists in case communication cannot be established, maybe due to a malfunction in the

PROFINET cable.

Provided encoder configuration and parameterization was successful (automated process) the cyclic data

communication will commence. The LED green continuous signals cyclic data exchange with the controller.

Upon occurrence of a position leap („code consistency error") or excess speed of more than 6200 rpm the

LED will change to red continuous for at least 2.5 s. If the signalized error remains or occurs repeatedly within

this time, red continuous will be extended correspondingly.

If the encoder receives a preset value outside the limits the LED will change to red flashing fast (5 Hz). This

alarm remains until the encoder is receiving an admissible preset value.

In case of incorrect parameterization by the master the LED is flashing red slowly (1 Hz). This may be due to

incorrect parameter input in the engineering tool. Most of incorrect inputs are prevented by the GSDML file,

but eliminating every error is not possible.

5.3. Activity indicator (green LEDs)

The bus cover provides two additional green Link / Activity LEDs to signal data communication status on

ports P1 and P2. During non-permanent data communication (e.g. during bootup) the LEDs flash irregularly.

In cyclic data exchange they are lit continuously.
