Communication with Elgas devices (Czech republic)

The ELGAS s r.o. company (, Czech republic) manufactures recounting devices for gas consumption measurements.
From the communication protocol point of view, the devices can be divided into two groups:

The ELGAS-2 protocol

The ELGAS-2 protocol is used by new generation of devices (since 2013).

For example for the following devices:

- ELCOR-2 (gas meter)
- DATCOM-2 (electronic logger for saving gas pressures and temperatures)
- DATCOM-RTU (technological process monitoring system, limit values monitor, slow process regulator ..)
- DATCOM-AMR2 / 3 (GSM/GPRS communicator for remote data transfers from gas meters)
- miniELCOR / maxiELCOR (battery operated gas meter designed for explosive environments)
For this communication in the PROMOTIC system can be used: PmElgas2 - Driver for communication with Elgas devices

The Daniel protocol

The ELCOR-94 device uses this communication protocol, (gas consumption meter), but it is not being manufactured since 2006.

The PROMOTIC system does not have dedicated communication driver for this protocol (although it can be developed if needed).

Based on the fact that this protocol is quite simple, the communication can be obtained by using the PROMOTIC driver:
