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? -

Flex, thank you that does clear up a lot. this is a new scale we are using. One Indicator with multiple scales so it had me kind of mixed up. we normally use one scale head per device and everything gets it own set up. thank you for taking the time to work me through that. -
This looks to me like a single device and you choose which scale reading via MODBUS command. I see no reason to close the connection, once established, nor any reason to use two sockets. I'm not familiar with these scales so I may be misinterpreting something. You can choose the timing between commands without closing the socket.
