6.2.6.3 Diagnostics in the case of invalid ET 200S configuration states
on the PROFINET IO
Invalid configuration states
The following invalid configuration states of the ET 200S lead to failure of the
ET 200S I/O device or prevent entry into data interchange.
•
Two missing modules
•
Bus termination module missing
•
Number of modules exceeds maximum configuration
•
Faulty backplane bus (for example, terminal module is defective)
Note
If one module is missing (gap) and the ET 200S is switched on, the I/O device will
not start up.
6.2.6.4 Diagnostics in the case of interruption of the ET 200S
backplane bus
If the ET 200S does not start or data interchange is interrupted, the cause of this
behavior could be a faulty terminal module. The faulty terminal module physically
interrupts the ET 200S backplane bus.
There is a 35-byte long manufacturer-specific diagnosis for the IM151-3 PN (slot 0)
for localizing a bus interruption. The module status and the ID-related diagnosis is
shown, as know with the PROFIBUS DP.
Contents of the manufacturer-specific diagnosis:
Byte 0 to 5:
reserved
Byte 6 to 14: ID-related diagnosis (see Figure 6-22)
Byte 15 to 34: Module status (see Figure 6-24)
No interrupt is generated if the ET 200S backplane bus is interrupted. The user
must specifically read this information. The data set with the index F00B
H
is
available for this.
