Selection Description
value from the PROFIBUS.
No number
(NAN = Not A
Number)
A calculation has not returned a valid number, for
example root of negative numbers.
Infinite value
(INF = infin-
ity)
A calculation is infinite, for example division by zero.
Inactive
This is set when a channel that is output, calculated or
used in any other way is not active at the start of a meas-
urement. Thus, you can see at run time which channels
are inactive.
Scale range
overrun
Scaling range exceeded.
Scale range
underrun
Scaling range not met.
Trigger block
end
End of a trigger block (data storage).
Input value
outside the
(permissible)
range
The source channel value cannot be processed, there is a
parameter error. Check the parameters specified.
Recursion
When a channel is used for a calculation and the input sig-
nal of that channel depends on the calculation, there is a
loop and thus a recursion. The
Meti OS software recog-
nises this; the calculation is terminated and this status is
set.
Overload
An analogue or digital input or output is overloaded. For
example, the power source for a Pt100 sensor may be
overloaded at one input. The load resistance could be too
small at one output, resulting in an excessive current.
