10 Troubleshooting and diagnosis options

Since no differentiated error causes can be indicated via the LED displays, the diagnostic options in
the two possible configurations should be used:
● PNO Encoder Profile: chapter "Warnings, errors, diagnosis" on page 144
● TR Encoder Profile: chapter "TR-Module Status and Control" on page 159 and
chapter "PROFINET diagnosis alarm" on page 161

10.1 Optical displays

The position and assignment of the LEDs can be found in the accompanying pin assignment, for
display states and flashing frequency, see chapter Bus status display on page 105.
