Supported device types and versions

...

The protocol supports the communication with devices ELCOR-2 and microELCOR-2 (made by company ELGAS) that recalculate a gas quantity., 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:

Communication station configuration

...

• Communication protocol: Elcor ELGAS-2 (CP II).
• Station address:
  • Node address: value in the range of 0 to 65535.

...

• • Address: meter address, a value in the range of 0 to 255.
  • If

...

• • both addresses are 0, the device must answer obligatorily.

Password for reading: maximum of 6 characters is allowed if the password is set in the device (only ELCOR-2 only).

Station protocol parameters

Configuration dialog box  - tab „Parameters".
They influence some optional parameters of the protocol. Following The following station protocol parameters can be set:

I/O tag configuration

...

Possible value types of I/O tags: Di, Ai, Ci, TxtI, TiA.

Device The ELCOR-2 device

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 morehigher). To find out the technical units - configure text of I/O tag with the address UNIT(ind).
