This read-only INTEGER reports the configured high alarm limit for a monitored channel on the TH2E device; the source DESCRIPTION for this specific object is blank, so its role is inferred from its position in the watch-value table alongside limitLo and limitHy. An admin reads this to know the upper threshold value that, when exceeded by the channel's reading, would trigger an alarm condition when modeWatch is enabled. For illustration, this object might report 300 as a high-temperature alarm threshold (e.g. 30.0 degrees) for a monitored channel.
