RTM Elster AMCO applicative PFS Coronis Systems
5.5.5.Time Of Use (TOU) buckets configuration and readings
RTM Elster AMCO offers the possibility to manage up to 6 TOU buckets. This means that each port has 7
totalizers, one for current reading and the 6 others corresponding to TOU Buckets.
ATTENTION:
Activating TOU Buckets on an unsynchronized RTM is not recommended. Indeed, this feature
highly depends on RTM RTC parameter which is automatically updated only when the RTM is
synchronized.
➔ TOU Buckets configuration
The parametrization can be done by using the standard reading and writing command (See section §4.2).
The parameter to read or write is the parameter 0x60.

ATTENTION:
RTM Elster AMCO check for coherence in the TOU buckets programming when user access to
the configuration parameter:
– If the number of TOU Buckets is lower than 2, then TOU buckets management will
be rejected (update status = error) even if it is activated.
– If starting hour list is not coherent, i.e. there are windows overlaps, RTM Elster
AMCO sends back to the initiator of the request an error status for parameter
writing access.
– When less than 6 TOU Buckets are expected, fields relative to not used TOU
buckets will not be treated by the RTM Elster AMCO for coherence. Parameter
length is always seven bytes.
