Configurable parameters
(factory settings are highlighted in bold)
Specify what data type the calculation returns. This setting affects how the
channel saves and is displayed. For example, if you add 2 analog channels,
the result is an "instantaneous value". If, for example, you logically link 2
channels (Digital 1 AND Digital 2), the result is a "state" (on/off).
Picklist: instantaneous value, state, counter, operating time, control
input, Efficiency
Notes on "The result is: Efficiency"
Efficiency = benefit / effort or "energy developed" / "energy supplied". To
calculate the rate of efficiency, it makes sense to track counter values over
a specific period. If the result type is set to "efficiency", the evaluation
counters of the channels used are used to calculate the value. The
efficiency is calculated separately for each evaluation and saved as a mean
value.
Example:
Analog input 1: gas (measurement of gas consumption of a steam boiler)
mathematics channel 2: steam mass
Mathematics channel 3: efficiency
Formula: MI(3;2) / AI(3;1)
Unit: kg/Nm (i.e. amount of steam generated per standard cubic meter of
gas) The result is: efficiency
Calculated result:
Evaluation 1: counter reading of evaluation 1 of mathematics channel 2 /
counter reading of evaluation 1 of analog input 1
Evaluation 2: counter reading of evaluation 2 of mathematics channel 2 /
counter reading of evaluation 2 of analog input 1
...
Set up the function of the control input.
"Start recording": data are displayed/stored only if the input is active.
"Set point monitoring on/off": the complete set point monitoring
function for the unit can be switched on (for High) or switched off (for
Low) (e.g. during cleaning cycles).
"Individual LV on/off": monitoring for a selected limit value can be
switched on (for High) or switched off (for Low).
"Start/stop analysis 1 - 4": starts or stops external analysis (the analysis only
runs if the signal is high). Measured value recording for the graphic display
continues.
Note: This function is not available for the "Batch" option!
Select what limit value should be switched on and off by means of this
control input.
Picklist: switched off, set point x
"Start/stop analysis 1 – 4": all the active channels are analyzed as long as
the control input is enabled, i.e. analysis based on the Min/Max/average
values, amounts and totalization does not take place cyclically at fixed
intervals. Analysis routines are controlled by this digital input. The analysis
starts when the input is activated. The analysis is completed and saved
when the input is deactivated. Measured value recording for the graphic
display continues. Batches can also be started/finished via this function.
Unit of the calculated value, e.g. if several flow inputs are calculated
together, the unit of the result can be entered here, e.g. m/h. 6–digit entry.
