The protocol supports communication with ELCOR-2, microELCOR-2, ELCORLite, miniELCOR,and ELCORplus devices (made by the ELGAS company ) that recalculate a gas quantity.
When communication is established, the current device configuration is read. From it, for each configured object (identified by the "Name" field), its address ("ID" field) necessary for the configuration of the I/O tag and the object type ("Object type" field) can be determined. Example of a reading:

Table 2 contains the list of the main parameters of the device.
Tables 3 to 8 contains the list of variable configuration and informative data according to the parameter type. DESC(ind) parameter represents the common data of all parameters. It describes the quantity. The current value of quantity can be acquired by the configuration of the I/O tag with numerical address - index ind (number from 1 and higher). To find out the technical units - configure text of I/O tag with the address UNIT(ind).
