5.RTM Elster AMCO functionalities
5.1.Fixed Network/Walk By/ Drive By switching method
(Refers to DR[5] Section 1.0.1)
According to §4.3.2 (Operating mode parameter description), RTM Elster AMCO is able to operate in “Fixed”
network, “Walk By”, and “Drive By” installations. The operation in “Walk By” and “Drive By” is exactly the
same.
RTM Elster AMCO operating in “Fixed” network mode just needs a setting command coming from a hand-
held computer to switch in “Drive By” mode operation. Conversely, once operating in “Drive By” (or in “Walk
By”), only a new setting command is required to make it switching in “Fixed” Network mode operation.
5.2.Datalogging management
(Refers to DR[3] Section 1.0.16 and 1.0.21; DR[4,5] Section 1.0.15 and 1.0.18)
The datalogging mode enables periodic logging of meter readings for each Port. The frequency of these
readings can be set in three different ways :
 data logging in time steps (selectable from 1 minute to 31 ½ hours),
 data logging once a week (day and hour of the day selectable),
 data logging once a month(date* and hour of the day selectable).
*when datalogging once a month is selected, date can be selected from the 1
st
to the 28
th
of each month.
Datalogging feature allows to store up to :
➢ 2100 readings when one Port is connected,
➢ 1050 readings when two Ports are connected,
➢ 700 readings when three Ports are connected,
➢ 525 readings when four Ports are connected.
Each Port has its own datalogging table. When the storage table is full, most recent logs overwrite oldest
ones.
Each time the datalogging settings are modified, storage tables are reset.
Datalogging table structure for one Port (A) connected:
