Siemens 6MD85, Manual

Page: 1047 / 1256

Parameter Value Description
0 min Deactivated
1 min to 60 min Cyclical transfer after the set time 1 minute to 60 minutes
Note: If the parameter is activated through a time setting, the parameter
Restore time
is not in effect and
will be deactivated automatically.
Parameter:
Edge trigger
•
Default setting:
(_:103) Edge trigger
=
rising edge
Parameter Value Description
rising edge
Counting with rising edge at the pulse input
rising & falling edge
Counting with rising and falling edge at the pulse input
Parameter:
Restore by absolute time
•
Default setting:
(_:104) Restore by absolute time
=
False
Parameter Value Description
False
Deactivated
True
The cyclic restoring of setting
Restore interval
after the set time is also
synchronized with the system time. Example:
Restore interval
= 30
min; current system time: 12:10 o'clock. First restoring operation: 12:30
o'clock; next restoring operation: 13:00 o'clock, etc.
Input Signals: >Pulse input, >External error, >Restore trigger, >Reset
Binary inputs Description
>Pulse input
Input for the counting pulses of an external pulse generator
>External error
Indication that the counter pulses of the external pulse generator are faulty.
The indication has an effect on the quality identifier of the pulse value.
>Restore trigger
The transfer of the metered values is initiated via a binary input.
>Reset
The rising edge at the binary input resets the pulse counter to 0.
The amount of energy indicated by a pulse generator is to be displayed as a measured value.
1 pulse corresponds to 100 Wh.
The pulse weighting, the SI unit, and the factor must be adjusted to one another.
Display value = Calculated metered value * Pulse weighting * Factor * SI unit.
If the check box Restore delta value is activated, the differential value is transferred at the restore time set
via the communication interface. The difference value is formed by subtracting the counter content of the last
restoring operation from the current counter content.
You route the logical signal
>Pulse input
to a binary input to which the pulse generator is connected.
Set the following values:
Name Active Power Meter
Pulse weighting 100
Restore differential value Activated
SI unit Wh
Factor 1
The factor is used for adaptation to larger units (for instance, 1000 for kWh). It is adjustable in powers of ten
(1, 10, 100, 1000, etc.). The following figure shows the signals that can be arranged in the DIGSI information
matrix. Open the function group where you created the pulse-metered value, for example, Line 1. There, you
will find the function area Pulse-metered value. Here you will also find the logical signals next to the
metered value. Select the metered value and enter the settings under Properties.
