2.8. Data recording and storage
Following daily, weekly and monthly parameter values are recorded in heat meter memory:
- absolute integral instantaneous parameter values (listed in Table 2.4)
- hourly, weekly and monthly alterations of integral parameters
- hourly, weekly and monthly average values for all measured temperature and pressure values
- error (fault) and information codes (see paragraph. 8.2.2) that occurred during the last hour, day
and month
Data logger
capacity:
up to 110 days (3,5 months) – for hourly records.
up to 1461 days (36 last months) - for daily and monthly records,
Archive data retention time
not more than 36 months
Retention time of measured integrated parametres
even if device is disconnected from power supply not more than 12 years
2.9. External communication modules and interfaces
2.9.1.
Optical interface
according to EN 62056-21:2003
(integrated into the front panel)
Optical interface is designed for:
- read out of values by protocol EN IEC 62056 or M-bus
- direct printing reports (by ASCII codes)
- read out archive data by protocol M-bus
- configuring of the meter by means of the special protocol
(parameterization mode is actuated by button “SET”)
- adjusting of the meter by means of the special protocol
(adjusting mode is actuated by jumper)
Programmable data transfer rate
(300 ... 9600) bps
with the "Even" parity or not.
2.9.2. Wire communication interfaces (as optional plug in modules)
- M-bus (according to EN1434-3);
- M-bus / CL / RS232 / two pulses outputs;
- M-bus /CL / RS232 / two current outputs;
- RS232,
- R485,
- MODBUS,
- RF 868 MHz (wireless),
- MiniBus
Wire communication interface (except MODBUS) protocol M-bus (according to EN1434-3)
Data transfer rate
Programmable (300 ... 9600) bps
with the "Even" parity or not.
Wire communication interface MODBUS protocol MODBUS RTU
2.9.3. Pulse -frequency and current outputs
