At least one Sercos slave does not react on time after the phase change to phase 3.

Reset the Sercos slave and start Sercos run-up again.

Wiring error detected (cable separated).

Verify and correct if necessary the wiring.

Non-Operating Sercos slave after the controller.

Verify the state and condition of the device and reset or replace if necessary.

ExtDiagMsg C_Time=20000

An error is detected during the parameter transfer for the configuration of the Sercos timing.

For example: One set ProducerCycleTime of a Sercos I/O device is not supported by the device.

Verify and correct if necessary the Sercos timing for the device.

ExtDiagMsg C_SP3-2000B

At least one Sercos slave does not react on time after the phase change to phase 3.

Reset the Sercos slave and start Sercos run-up again.

ExtDiagMsg C_SP3-20037

For at least one Sercos slave, an error is detected during synchronization command execution.

oReset the Sercos slave and start Sercos run-up again.

oVerify and correct if necessary the Sercos device.

ExtDiagMsg C_SP4 =20028

The number of configured additional real-time parameters is exceeded.

Verify and correct if necessary the parameters AdditionalIDNListMDT and AdditionalIDNListAT.

ExtDiagMsg ReconfSercAddr

Automatic distribution of unique Sercos addresses to the devices not using IdentificationMode SercosAddress was not successful. The Sercos run-up is aborted.

Refer to 8042 Sercos phase switched.

ExtDiagMsg Wrong Topology

Using IdentificationMode TopologyAddress /2 the Sercos bus can only run-up in bus-topology 'Line' on port 1 or in bus-topology 'Ring'.

Verify and modify if necessary the Identification Mode if using an unsupported topology.
