51 0 No or unknown FSM module or faulty
driver supply
Cause: Internal voltage error of the safety module or of
the fieldbus activation module.
Action: Module presumably defective. If possible,
replace with another module.
Cause: No safety module detected or unknown module
type.
Action:
 Install safety or fieldbus activation module
appropriate for the firmware and hardware.
 Load firmware appropriate for the safety or
fieldbus activation module, see type
designation on the module.
2 FSM: different module type Cause: Type or revision of the module does not fit the
project planning.
Action:
 Check whether correct module type and
correct version are being used.
 With module replacement: Module type not
yet configured. Accept currently integrated
safety or fieldbus activation module.
3 FSM: different module version Cause: Type or revision of the module is not supported.
Action:
 Install safety or fieldbus activation module
appropriate for the firmware and hardware.
 If only a module with a more recent version
is available: Load firmware that is
appropriate for the module, see type
designation on the module.
Cause: The module type is correct but the module
version is not supported by the basic device.
Action:
 Check module version; if possible use
module of same version after replacement.
Install suitable safety or fieldbus activation
module for the firmware and hardware.
 If only a module with a more recent version
is available: Load firmware that is
appropriate for the module, see type
designation on the module.
4 FSM: Fault in SSIO communication Cause: Error in the internal communication connection
between the basic device and the safety module.
