Hello experts,
we are using the EtherNet/IP adapter v1.0.3.4 on out AM4376 device. When the device is operating in a DLR netword with an active ring supervisor, the active supervisor address (MAC and IP address) is provided by at the following register offests within the ICSS shared data RAM:
DLR_ACTIVE_SUP_MAC_0123 = 0x154
DLR_ACTIVE_SUP_IP_OFFSET = 0x164
The MAC address of the active ring supervisor is always provides at offset DLR_ACTIVE_SUP_MAC_0123, but the IP address of the ring supervisor only sometimes contains the right value. In all other cases, the IP address is 0.
What could be the reason why the IP address of the active ring supervisor is provided with 0?
Best regards
Stefan
