Selection Description
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.
4.11.23 Status monitoring
This software channel monitors the source and becomes active (switches
to " On" ) when the source assumes the specified status.
