diagnostics are stored in the status archive. In the settings archive, operations that affect the
device parameters are recorded for service and metrology purposes when changing the settings.
In addition, other archives are available; for more details, refer to Section 11.3.
The device is equipped with serial interface RS232/RS485 for communication with superior
system. The various communication protocols installed in the device allow easier connection to
SCADA systems. The device can be supplied with built-in modems of both modern fast
communication networks and older 2G networks. In the event of an alarm condition, the device
can initiate the connection itself. The device also works with standard telephone, radio, GSM and
GPRS modems via the RS232/RS485 line.
The device allows wide-range user parametrization. The device can be configured using the
keypad of the device or the supplied PC software (see [42] or [43]). This software also allows
reading, displaying and archiving both actual measured values and the internal archives contents.

Trade Name of the Device
These instructions specify the features and parameters of ELCOR and
ELCOR plus correctors. The device is also marketed as DATCOM and
DATCOM plus electronic data logger. To some foreign markets, the device can
also be supplied with a mechanical indexer under the name ELCOR plus Indexer .
These instructions apply to devices marketed under any of the trade names
mentioned above.
All the mentioned devices (both correctors and data loggers) are identical
devices from the technical point of view (technical parameters, features) as
well as from the safety point of view (ATEX). However, the DATCOM and
DATCOM plus data loggers have not approved gauges and cannot be used for
billing purposes.
As concerns DATCOM and DATCOM plus loggers, the metrological parameters
stated in this document are not assessed under the 2014/32/EU (MID) Measuring
Instruments Directive about putting measuring instruments on the market (NV
120/2016 Coll.). No additional metrology marking is attached to the CE conformity
marking.
