2.9. Data recording and storage
Foll
owing daily, weekly and monthly parameter values are recorded in calculator’s memory:
- absolute integral instantaneous parameter values (listed in Table 4)
- hourly, weekly and monthly alterations of integral parameters (listed in Table 4)
- hourly, weekly and monthly average values for all measured temperature and pressure values
- error and information codes (see paragraph. 8.2.1) that occurred during the last hour, day and
month
Archive data is retained even if device is disconnected from power supply for the whole lifetime
period.
Data logger capacity:
up to 32 last months
–
for daily and monthly records,
up to 3,5 last months (2600 hours) - for hourly records.
2.10. External communication modules and interfaces
Optical interface
EN 62056-21:2003 (IEC 62056-21:2002)
(integrated into the front panel)
The following communication modules are available as options:
Two configurable pulse-frequency outputs
Class OD;
(available only with optional plug-in multi 18 V (when mains supply)
module SKU46 with pulse outputs) Passive (U
max
42 V, I< 20 mA )
Two configurable current outputs
(available only with optional plug-in multi
module SKU45 with current outputs)
0-20mA or 4-20mA
Configurable double relay output
for limiting regulation or alarm function
Available only with mains power supply module
(see paragraphs 2.11 and 2.12)
230V, 2A
Serial digital communication interface
M-bus, CL or RS -232
(as optional plug-in module)
RF-module
868 MHz
(as optional plug-in module)
Two pulse outputs for testing
Class OD;
(terminals 16;17;18) 3,5 V

0,3 V;
Permissible loading current up to 0,1 mA
The configurable pulse-
frequency output in “pulse mode” can be used for thermal energy ( 
E, E1,
E2, E3) or quantity of water V1 (M1), V2(M2), V3(M3), V4(M4), V5 pulses Pulse value will correspond
to the lowest digit of indicated parameter.
The configurable pulse-frequency (or current - module SKU45
) output in “frequency mode”
(available only with mains power supply module) can be used for thermal power ( P1, P2, P3), flow rate
(q1, q2, q3, q4), temperature or temperature difference (
