Diagnostics options
The following diagnostics options are available:
LEDs of the module
For information on the LED displays, refer to the section LEDs (Page 40).
If there are connection problems between the master station and station, you can, for
example see whether or not the transmission path is disturbed or whether the CPU is in
STOP status by checking the LEDs.
Diagnostics SMS / e-mail
If configurable events such as the lack of reachability of a partner or if the CPU changes to
STOP, the CP can send a diagnostics SMS message or e-mail.
The configuration is described in section Message configuration (Page 163).
STEP 7 Basic: The "Diagnostics" tab in the Inspector window
If you access the CP via Ethernet, you obtain the following information about the selected
module:
●
Entries in the diagnostics buffer of the CPU
●
Information on the online status of the module
Access via WAN networks does not provide any information.
STEP 7 Basic: Diagnostics functions via the "Online > Online and diagnostics" menu
Using the online functions, you can read diagnostics information from the CP from an
engineering station on which the project with the CP is stored.
If you want to operate online diagnostics with the station via the CP, you need to select the
type of communication "Enable online functions"; see section Communication types
(Page 67).
