Function “Addition/Subtraction”: for impulse counter.
“Sum/average”: via impulse or operating time counter.
“Logical combination”: for control input, logging in/out, operating time and events + operating time
! Note!
Only those channels that it makes sense to combine can be selected. Combinations are processed like real signals, i.e.
they are updated every second, can be monitored for limit values and allocated to groups, etc.
Formula Description of the combination. Can not be changed (just for your information).
Sum of For “Sum/average” function:
Selection as to whether impulse or operating time counters are to be combined with each other in this combination. Can
only be selected when “Sum/average” is to be formed.
Channel identification Explanation (or designation of the combination carried out here).
Function “g” For “Sum/average” function:
Selection as to whether the average or the sum is to be calculated from channels “y1” to “y2”.
Input “y1” Input “y1”, which is to be combined with another.
! Note!
Other combinations can be used if their number is lower than the number of the current combination. In this way, for
example, combination 1 can be further processed in combination 2 (“Cascading”).
Logic condition y1 Only for “Logical combination” function:
Logic condition of input y1 at which the selected combination takes effect.
Selection: “High” or “Low”
Factor “a” For “Addition/Subtraction” function:
Factor “a”, by which the value from signal “y1” is multiplied.
Factory setting: 1.
Combination “?” For “Addition/Subtraction” function:
Addition/Subtraction: adds or subtracts both channels / formula parts.
“Not used”: switches part 2 of the formula (y2*b) off.
For “Logical combination” function:
“AND”: both inputs must accept the specified conditions in order to be recognised as logically true (“H”).
“OR”: it is sufficient if only one of both inputs accepts the specified condition.
Input “y2” Input “y2”, which is to be combined with another.
! Note!
Other combinations can be used if their number is lower than the number of the current combination. In this way, for
example, combination 1 can be further processed in combination 2 (“Cascading”).
Logic condition y2 Only for “Logical combination” function:
Logic condition of input y2 at which the selected combination takes effect.
Selection: “High” or “Low”
External switch Only for “Logical combination” function:
Switches the corresponding relay (or OC output) when the combination is logically true (“H”). The terminal numbers are
shown in brackets. Please refer to the connection instructions.
Factor “b” Addition/Subtraction: factor “b” by which the value of signal “y2” is multiplied.
Sum/average: factor by which the sum or the average of the channels “y1” to “y2” is multiplied.
Constant “c” Constant “c” is added to the result of the combination of both signals “y1” and “y2”.
Entry in this combination's (technical or physical) unit.
Factory setting: 0.
Engineering units Combination's technical (physical) unit, e.g. “piece” for summation of produced units.
Decimal point Number of places after the decimal point for the display and the limit value entry (counter limit value).
