The messages appear at the terminals that are defined in the DEVLS parameter of
the LS point.
This (calculation) message is a diagnostic message and allows monitoring the peak
demand program for a specified time at the end of each period.
The messages only appear if the parameter LSCM <> 0 (i.e., is unequal to zero) in the
LS Point NAME. The LSCM time applies to the end of the period only. During this time
(programmed in LSCM in minutes) this message is printed (normally every minute),
providing a check on the momentary demand.
vv = Parameter LS of the LS point
xx/yy = Parameter ONLM or OFLM of the LS point
zz = Correction value
If vv is not within the xx..yy interval, then the peak demand program must correct the
course of the demand by switching it.
zz is an internally used value that is used to fix the load to be switched. It is dependent
on how far vv lies outside the xx..yy interval, and from this, how long the current period
will last.
None. Diagnostic message for monitoring the peak demand program.
