Message Description Corrective Action
Cannot be executed in
the current mode.
A fatal error (abort) has occurred,
and the MS indicator flashes red.
Check the switches to see if they are set correctly. Otherwise, execute a
reset to clear the configuration data.
The device is locked. The configuration is locked and the
LOCK LED indicator is lit.
Unlock the device.
The TUNID is different. The safety network number (SNN)
has not been set since the device
reset (the NS LED indicator flashes
green and red), or the SNN in the
device disagrees with the SNN
downloaded from RSNetWorx for
DeviceNet software.
1. Reset the device to its default settings and download the parameters
again.
The SNN may be different than other devices. If the controller’s
alphanumeric display shows d6 and a Safety I/O Connection
Establishment Failure message appears in the error history table after
the operating mode has been changed, go to the next step.
2. Choose Network > Upload from Network in RSNetWorx for
DeviceNet software. Unify the SNN across the network and reset all
devices to the default settings. Once they are reset, download the
parameters to the devices again.
