Command Details: Process_CIP_Routing_Request
Category
Extended
Details
Command Code: 12h
Valid for: Object Instance
Description
The module will strip the first path within the Unconnected_Send service and evaluate whether or not
it’s possible to continue with the routing (e.g. check that the requested port exists within the port object).
If the stripped path was the last path the contents delivered to the application will be the CIP request
sent to the destination node, otherwise it will be an Unconneced_Send service with updated route path
information.
The module supports one pending request. Additional requests will be rejected by the module.
Note: Since the telegram length on the host interface is limited, the data must not exceed 255 bytes in
length. If it does, the module will reject the originator of the request (‘Resource unavailable’), and this
command will not be issued towards the host application.
