The device I am integrating to only allows ULINT reads for the extended 6 digit Modbus registers resulting in a value of 64 bits. There are 4 individual integers that contain date for separate tags that I need to parse out. An additional issue is that some of these integers are writable resulting in a requirement to reassemble the ULINT and write to the MTQ22. Has anyone dealt with this situation before?

Thanks for the help.
