86 Device is producing zero length data (idle state) while
module is in Run mode. Check device configuration and slave node status.
87 The primary owner has not allocated the slave. Put the primary owner online.
88 The connection choices (polled, strobed) between the
primary connection and the shared input only connection do
not match. Reconfigure the shared input-only connection's choices to
be the same as, or a subset of, the primary connection's
choices.
89 Slave device initialization using Auto Device Replacement
parameters failed. Put the slave device into configurable mode.
Check the slave's EDS file, if the slave is configured offline.
Check to see if the slave device has been replaced with an
incompatible device.
90 User has disabled communication port. Check Module Command Register for DISABLE bit set.
91 Bus-off condition detected on comm port. Module is
detecting communication errors. Check DeviceNet connections and physical media integrity.
Check system for failed slave devices or other possible
sources of network interference.
92 No network power detected on communication port. Provide network power. Make sure that module drop cable
is providing network power to module comm port.
