Can I set a TDA from within a process model?I received the error messageProgram Abort: KP cannot be called from process context.

Solution

No, TDAs (transmission data attributes) may only be set from within pipeline stages (.ps.c).However, once a TDA has been set, its value may be read from anywhere via the op_td_get... series of Kernel Procedures (KPs).As an alternative to TDAs, you may want to consider one of the following approaches:- If it supports your needs, set the TDA within a pipeline stage- Set a 0-bit packet field in your packet format, and use that field to store the data. Since the field's modeled size is 0 bits, it will not affect transmission, propagation, etc. of the packet.- Associate an ICI with the packet, and set the information in the ICI instead. For more information on these topics, refer to Modeler's Modeling Concepts manual, chapter Communication Mechanisms.
