The value is 1 if a safety controller has not been found on FC_IN.
The value is 2 if a safety controller has been found on FC_IN and the compatibility test
is in progress.
The value is 3 if a compatible safety controller has been found on FC_IN and the safe
sensor cascade is operational.

Diagnostics information on the individual Flexi Loop nodes
The indices 285 (11Dh) to 288 (120h) contain diagnostics information on the individ‐
ual Flexi Loop nodes.
Each index is 4 bytes long. The 32 bits are each allocated to one of the Flexi Loop
nodes:
•
bit 0 = Flexi Loop node 32
•
bit 31 = Flexi Loop node 1
Shutdown information
The value in index 285 (11Dh) indicates the output state of the safety sensors or safety
switches connected to the Flexi Loop nodes. Bit 0 to 31 correspond to the Flexi Loop
nodes 32 to 1.
•
The bit is 1 if there is no shutdown on the Flexi Loop node.
•
The bit is 0 if there is a shutdown.
Static testing
The value in index 286 (11Eh) indicates static errors (cross-circuit or short-circuit) on
the safety sensors or safety switches connected to the Flexi Loop nodes. Bit 0 to 31
correspond to the Flexi Loop nodes 32 to 1.
•
The bit is 1 if no error occurred.
•
The bit is 0 if there is a cross-circuit or short-circuit.
Dynamic testing
The value in index 287 (11Fh) indicates dynamic errors (discrepancy or sequence error)
on the safety sensors or safety switches connected to the Flexi Loop nodes. Bit 0 to 31
correspond to the Flexi Loop nodes 32 to 1.
•
The bit is 1 if no error occurred.
•
The bit is 0 if there is a discrepancy or sequence error.
Node detected
The value in index 288 (120h) indicates which of the Flexi Loop nodes is physically
present. Bit 0 to 31 correspond to the Flexi Loop nodes 32 to 1.
•
The bit is 1 if the Flexi Loop node is present.
•
The bit is 0 if the Flexi Loop node is missing.
7.4.3.5
Output options
The output options for the Flexi Loop nodes can be changed in a volatile manner using
the service data. Volatile parameters can only be used if the corresponding parameter
in the configuration has been set to the value logical 0.
Each index is 4 bytes long. The 32 bits are each allocated to one of the Flexi Loop
nodes:
•
bit 0 = Flexi Loop node 32
•
bit 31 = Flexi Loop node 1
