RTM Elster AMCO applicative PFS Coronis Systems
5.5.RTM reading management
(Refers to DR[3] Section 1.0.22; DR[4,5] Section 1.0.19)
RTM Elster AMCO offers the possibility to recover different types of readings listed below:
➢ Current reading,
➢ Daily consumption profile readings,
➢ Datalogging table,
➢ TOU buckets.
These different way to recover reading from RTM Elster AMCO are described in details in this section.
Furthermore, RTM Elster AMCO sends back on each of these requests, control information formatted as a
generic header described below. This one is useful to manage network supervision.

(1) “Profile selection” parameter is useful to inform the user software on current profile selected on RTM
Elster AMCO. Indeed, user software needs to use this parameter to be able to handle correctly the data
received format.
(2) The QoS value gives an image of the previous radio reception signal strength.
(3) The “life counter” value gives an estimated quantity of energy that remains in RTM Elster AMCO battery.
User software has to take into account the default value of this counter to compute an estimated remaining
lifetime.
(4) This field has different meaning and format depending on RTM Elster AMCO profile selected:
