Diagnostic messages and activation of the group error LED
If an error occurs during startup, the read group LED (SF) of the TIM lights up and a
message to this effect is entered in the diagnostic buffer of the TIM.
If the TIM is installed as a CP in an S7-300 rack, a diagnostic interrupt is sent to the CPU.
The following table contains a summary of all error messages that caused the group error
LED (SF) to light up.

3.7 Messages in the diagnostic buffer of the CPU
Introduction
The SINAUT TD7onCPU software package generates a series of operating and error
messages that are entered in the diagnostic buffer of the CPU. These can be displayed in
SINAUT / TD7 CPU Diagnostics . If a PG is connected and if this is registered for CP
messages, these diagnostic messages are displayed on the PG immediately when they
arise.
