The H2-DM1E PLC\'s authentication protocol appears to utilize either a custom encoding scheme or a challenge-response protocol. However, there\'s an observed anomaly in the H2-DM1E PLC\'s protocol execution, namely its acceptance of multiple distinct packets as valid authentication responses. This behavior deviates from standard security practices where a single, specific response or encoding pattern is expected for successful authentication.
