What hop count did you use on the initial PLM serial call. The Controller will bump the initial hop count if it retries a command due to a lack of response. The hop count does not matter as far as determining the messages are logically duplicate. If nothing else the link record address is the same in both ALDB responses. I know of no way to prevent or suppress what you are seeing. Process the first and ignore the second as a duplicate. You may get some ideas from other users on the Smarthome forum. There are a number of users writing their own PLM interface code. As far as a check sum I don’t know what you would compare it against. There is no way to know what the source message looked like coming from the device the ALDB command was originally sent to.
