Gossen Metrawatt GmbH 65
Analog Value Function
All other network variables can be read in as analog values.
Settings:
CMODE k = 5 LonA
. The desired value is selected by means of the network
variable number under LonCHANNEL.
LonCHANNEL k = Nv#
. The displayed
unit of measure is the power unit of measure.
12.3.3 U1681, U1687 and U1689 Electric Meters
Settings:
CMODE k = 4 LON
. Desired energy is selected via LonCHANNEL.
LonCHANNEL k = 1
reads out active energy import,
LonCHANNEL k = 2
reads
out active energy export. Corresponding power is read out automatically.
Energy Values and Corresponding Power

12.3.4 U1660 8-Channel (S0) Meter Polling Module
Energy Meter Function
Settings:
CMODE k = 4 LON
. The desired input is selected via LonCHANNEL.
LonCHANNEL k = 1...8
reads out the number of meter pulses from channels 1
through 8, from which energy is calculated by the summator. Corresponding
power is calculated by the U1660 and read out automatically. The meter constant
(Mconst) is transmitted to the device during installation to this end.
Binary Input Function
A U1660 meter polling module can be assigned to each of the channels of the U1601.
Settings:
CMODE k = 7 LonI
. LonINP reads out the status of all 8 S0 inputs of the U1660.
The energy meter function of the U1660 remains unaffected. Each input
corresponds to one bit:
Input 8 7 6 5 4 3 2 1
Bit 8 7 6 5 4 3 2 1
Example:
LonINP 3 = 3
means U1660 at channel 3, inputs 1 and 2 on, all
others off.
