If too many log entries are made in a short amount of time,
some of the entries may be lost. An important factor to con-
sider within this context is the speed of the memory card being
used. If logging is triggered via function block inputs T1 through
T4, this problem can be avoided by only having one save oper-
ation be triggered if the function block is not in the "logging dis-
abled" state.
