Hello; I am new to the forum and I have the following question; I have to implement a Unistream USC-B5-TR22 on a CAN Bus and I can see that this PLC has a sniffer function, I have tried to obtain information regarding how to use it and implement it in a project but I have not found it or I have been searching wrong, I Can you help by telling me where to find information such as videos, tutorials, etc. I would be grateful. Greetings Guille71

Does anyone know of any companies that do repair and mobile SERVICE in Michigan for Unitronics?

For the custom alarm type, you can specify HiHi, Hi, Lo, and LoLo limits that will trigger the alarm. Is there any way to tell which of the four limits has been exceeded when the alarm is triggered, other than manually comparing the PV value to each of the limits? The documentation says: This seems to imply that these are four separate alarms (Hi, HiHi, Lo, and LoLo), but as far as I can tell, exceeding any of the limits will all generate the same one alarm. If that's the case, what's the point of being able to specify a HiHi or LoLo alarm limit when this alarm will already have been triggered when the Hi or Lo limit is exceeded?
