Procedure for accessing the module diagnostics
The functions of the module or channel diagnostics display the current errors in which are classed according to their category: l internal errors (internal software errors, communication error with the processor, configuration, parametering or command error), l l external errors(slave device failed, AS-i supply switched off, terminal error, difference between physical configuration and PL7 configuration), other errors (module absent or switched off).
A faulty module becomes apparent when certain lights change to red, such as: l in the configuration editor at rack level: l the module position light, l in the configuration editor at module level: l the lights RUN , ERR and I/O , l the light DIAG .
A faulty channel becomes apparent when certain lights change to red, such as: l in the configuration editor at rack level: l l the module position light, in the configuration editor at channel level: l the light DIAG .
