The Equipment sends this message in response to a Host S2F47 and reports the
characteristics of limits for specified variables. In response to a request from the Host for
all limits for all variables, only variables with limits defined are reported. If the Host
requests specific variables which are not eligible for limits monitoring, the following
message will be reported for that variable:
S2F48 * H <- E
<L
<L [2]
<U4 VID> * Variable ID
<L> * Not eligible for Limits
