One of the messages listed below in the Channel Status indicates that the maximum tonnage recorded

When the condition is detected on any channel, a Top Stop is issued.

When the condition is detected on any channel, a stop is issued. The type of stop issued depends on
whether the high setpoint is a peak high setpoint or a data window high setpoint. A peak high alarm will
issue a stop as configured by the “Peak High Limit Stop Type” setting. A data window high alarm will
issue a stop as configured by the “DW High Limit Stop Type” setting. See section 4.4.13 on page 46 for
details on these settings.
