System diagnostics
with the network, via
the
I/O diagnostics interface
Internal diagnostics data can be read via the
I/O diagnostics interface. In this way, detailed
diagnostic information can be accessed, even
if the network used does not offer any exten-
sive network-specific diagnostic functions.
The I/O diagnostics interface offers:
–
Access to the current error message
–
Access to the diagnostic memory
–
Read access to internal parameters and
data

Error numbers
Possible errors of the energy efficiency module are divided into three error classes with different
priorities depending on the seriousness of the error. If an error occurs, the system error SF LED will
flash depending on the error class.

Tab. 80: SF LED, system error
If several errors occur simultaneously, the error with the highest priority will have precedence. This
means that:
–
the system error LED flashes according to the higher priority
–
the number of the error with the higher priority will be entered in the system diagnostic data under
function number 1938, error number.
