In the current firmware version, the device is equipped with several communication protocols. The
device is extendable by additional protocols according to customer requirements. By default, the
following protocols are implemented:
ELGAS ver. 2,
MODBUS RTU
MODBUS TCP
MODBUS IGD
M900
GAZ MODEM
(other communication protocols are being prepared)
When using MODBUS protocols, a map of the MODBUS registers must be loaded to the device.
The map assigns the numeric addresses to the measured and calculated quantities stored in the
internal memory of the device. The Modbus map can be uploaded to the device by user-operated
SW [43].
The ELGAS protocol ver. 2
is the native protocol of the device. A complete set of features
implemented in the device is available. The utility SW [43], [42] uses this protocol only; to switch
to another data link layer, the ELGAS version 2 protocol is just nested in another data link layer
(the tunnel). Only the ELGAS version 2 and CTR protocols can be used to download the firmware
(protected by a metrological seal).
If
MODBUS protocol
s are used, the MODBUS register map must be uploaded to the device. The
map assigns numerical addresses to an individual measured and calculated quantities stored in
the internal memory of the device. The Modbus map can be loaded into the device by the user
service SW [43].
