6.1.3 EPLCN_PCK_REGISTER_REQ/CNF – Registration at NMT State Indication
Notification Table
This packet registers a queue for state indications of the NMT state machine. Afterwards, the AP task
will be able to receive state change indications.
If all registration slots are already used for registered queues, the confirmation packet will return the
error status code TLR_E_EPL_NMT_NO_MORE_APP_HANDLES(0xC017001B).
Note: As long as this packet has not been received, the AP-task will not receive any state
change indications.
Note: This packet is not used if accessing the firmware via the DPM.
Use the registering functionality described in the netX Dual-Port-Memory Manual instead
(RCX_REGISTER_APP_REQ, command code 0x2F10).
