5.5.4 Addressability of Meter
The meter monitors every communication request received over the optical
interface or the AMR interface. The AMR interface can be controlled by
various inputs from the module (e.g. CS interface input).
With FW versions M23 or higher, the meter will react to the communication
request only under either of the following conditions:
If the request contains no address,
If the address matches with the address of the meter.
The address of the meter is preset to the serial number of the meter.
For FW versions prior to M23, the meters react only, if the request contains
no address.
If the meter is connected to a communication bus with several meters, the
communication request must be started
with
an address. Otherwise a
communication conflict between the meters will occur
.
5.6 Password
Lock-out
The meter can be configured to lock-out the optical interface for a period of
up to 255 seconds in 1 second increments. Default lock-out time is 60
seconds.
When a communication event is invoked with an incorrect password,
access is denied. The denial of access continues for the period of the
timeout (i.e. the meter remains signed on for the invalid password timeout
period). Even if the password is corrected, the invalid password timeout has
to expire before retrying is allowed.
