Description
A request to modify a non-modifiable member was received.
This error code is reported by DeviceNet Group 2 only. It is used
only as substitute for those with a code space of 4K or less, for the
service not supported, for the attribute not supported, and for the
attribute not settable.
A CIP to Modbus translator has received an undefined Modbus
exception code.
A request to read a non-readable attribute was received.
The object supports the service, but not for the designated
application path (for example, attribute). Note: This cannot be used
in cases where more specific general status codes are applied.
Example: 0x0E (attributes are not settable) or 0x29 (members are
not settable).
Reserved by CIP for future extensions.
This range of error codes is to be used to indicate errors specific to
the object class. Use of this range should only be performed when
none of the error codes presented in this table accurately reflect the
error that was encountered.
