Device The ELCOR-2 device

Table 2 contains the list of 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 address UNIT(ind).
