Description of INFO message
Principal content of INFO message are statuses (readings) of watermeters, monitored by the module. Together
with these readings there are also some identification and operational information of the module itself. The INFO
messages are broadcasted in regular intervals preset by ”periode” parameter (see paragraph
Fixed part of the message
is comprised of the first nine variables, that are contained in each message. In the
table below there are marked in the OID field by yellow colour.
Variable part
of the message contains set of measured values that depends on setting of the
message mask
by
”smask” command. If only
current values
are transferred, the message contains only one set of measured values,
without timestamps. If
historical readings
are transferred (see setting of ”hist” parameter in paragraph
the message contains several sets of measured values with appropriate
”timestamp”
before each set. One set of
measured values contains one or more variables for each watermeter read by the module.
By setting of ”mask” parameter following variables can be selected for transfer:
OID 205/x - watermeter number (ID) with index ”x”
OID 98/x - watermeter
”
alarm flag” with index ”x”
OID 201/x - watermeter message RSSI with index ”x”
The message always contains watermeter counter value (OID 100/x), this variable cannot be switched off.
The variables are linked to individual watermeters by using of index ”x”. Indexes are assigned to the watermeters
in the Table of read watermeters (see paragraph
) edited by ”sid [index] [value]” command.
If there are historical data transferred, OID 205/x variable carrying watermeter ID is transferred only once, at the
beginning of variable part of the message. Here there is a set of OID 205/x variables that forms a list of watermeters
read by the module with their indexes. Sets of historical readings do not contain OID 205/x variables then.
