Table 67: Blink code table for the 'I/O' LED signaling, error code 10
Error code 10: "PLC program fault"
Error
Argument
Error Description
Solution
1
Error when implementing
the
PFC run time system
1. Restart the fieldbus controller by turning the power
supply off and on again.
2. If the error still exists, please contact the I/O Support.
2
Error when generating
the PFC
inline code
1. Restart the fieldbus controller by turning the power
supply off and on again.
2. If the error still exists, please contact the I/O Support.
3
An IEC task exceeded
the maximum running
time or the sampling
interval of the IEC task
could not be kept
(Watchdog)
1. Check the task configuration concerning the adjusted
sampling intervals and watchdog times.
4
PFC Web-Visualization
initialization error
1. Restart the fieldbus controller by turning the power
supply off and on again.
2. If the error still exists, please accomplish a reset
(origin) in WAGO-I/O-
PRO
.
3. Compile the project again.
4. Transfer the project to the controller.
5
Error when synchronizing
the PLC configuration
with the local bus
1. Check the information of the connected modules in
the PLC configuration of WAGO-I/O-
PRO
.
2. Compare this information with the modules that are
actually connected.
3. Compile the project again.
4. Transfer the project to the controller.

Error code 11: "Gateway-/Mailbox I/O module fault"
Error
Argument
Error Description
Solution
1
Maximum number of
Gateway modules exceeded
1. Turn off the power supply of the node.
2. Reduce number of Gateway modules.
3. Turn the power supply on again.
2
Maximum size of Mailbox
exceeded
1. Turn off the power supply of the node.
2. Reduce the Mailbox size.
3. Turn the power supply on again.
3
Maximum size of process
image exceeded due to the
put Gateway modules
1. Turn off the power supply of the node.
2. Reduce the data width of the Gateway modules.
3. Turn the power supply on again.
* The number of blink pulses (n) indicates the position of the I/O module.
I/O modules without data are not counted (e.g. supply module without diagnosis)
