Description
By setting the 'Enable CIP Request Forwarding'-attribute (#11), all requests to unimplemented CIP-objects and
unknown assembly object instances, will be forwarded to the host application through this command. The
application then has to evaluate the request and return a proper response. The module supports one CIP-
request; additional requests will be rejected by the module.
Note that since the telegram length on the host interface is limited, the request data size must not exceed 255
bytes. If it does, the module will send a 'resource unavailable' response to the originator of the request and
the message will not be forwarded to the host application.
This command is similar - but not identical - to the 'Process_CIP_Request'-command in the Anybus
CompactCom 40 DeviceNet.

When using this functionality, make sure to implement the common CIP Class Attribute (attribute #1,
Revision) for all objects in the host application firmware. Failure to observe this will prevent the module
from successfully passing conformance tests.
