Possible reasons
If WS0-CPU1: EFI device address
conflict:
 There are at least 2 CPU modules
with the same EFI address
connected.
If WS0-CPU1 and Flexi Link: Wrong
Flexi Link ID:
 EFI1 and EFI2 is swapped in the
wiring.
 There is at least 1 CPU module
with a different Flexi Link ID
connected.
Configuration in memory plug is
incompatible for at least one safety I/O
module:
 Wrong type or version of module
(whose MS LED is flashing red or
red/green).
 Too many safety I/O modules are
connected (whose MS LED is
flashing red or red/green).
 Safety I/O modules are missing
(MS LED of all other modules is
flashing red or red/green).
System is in Stop state (ready to run).
System is in Stop state (ready to run).
System is in operation. No error
detected.
Module power supply of WS0-XTIO is
too low or missing.
Chapter 10
Possible measures
 Change the EFI device address
with Setting and Monitoring Tool,
either of the CPU module or of the
connected device.
 Check wiring between the Flexi Link
stations: EFI1 connected with EFI1,
and if applies EFI2 with EFI2.
 Connect Flexi Link stations with
matching Flexi Link IDs.
 Download configuration to all Flexi
Link stations with same Flexi Link
IDs.
 Download a configuration with the
same module type and the same or
a smaller firmware version for all
safety I/O modules.
 Replace the affected safety I/O
module in the hardware installation
by a module with the same module
type and the same or smaller
firmware version as selected in the
project file.
Start application in Setting and
Monitoring Tool.
For automatic start after power up a
verification of the project is necessary
with Setting and Monitoring Tool.
Start application in Setting and
Monitoring Tool.

Check supply voltage at terminals A1
(24 V) and A2 (0 V) at the WS0-XTIO
module, also under worst case load
conditions.
Error is reset automatically after
approx. 8 seconds, if the error reason
no longer exists.
