10.1 Diagnostics
Reading out diagnostics information of the connected readers
Proceed as follows to read the diagnostics information of the readers connected to the
communications module using STEP 7 Basic / Professional (TIA Portal):
1. Switch to the device view of the communications module.
2. In the device overview, right-click on the desired reader module and click on the "Online
& Diagnostics" entry in the shortcut menu.
Diagnostics with enabled diagnostic interrupt messages
If diagnostic interrupt messages are enabled, the error messages are stored in the CPU
diagnostics buffer in plain text. You can further process these messages with the appropriate
function blocks, e.g. so that they are forwarded to an HMI.
Error states are displayed by a red tool symbol in the online device view when diagnostic
interrupt messages are activated. Right-click on the affected module and click on "Online &
Diagnostics" in the shortcut menu to view the error text underneath the "Channel
diagnostics" entry.
Diagnostics using the "SIMATIC Ident" technology object
Alternatively, you can also diagnose the communications modules using the "SIMATIC Ident"
technology object. You can find detailed information on this in the TIA Portal help.
