Possible I/O tag types: Di, Ai, Ci, TxtI, Ao, Co.

The address of the I/O tag is entered in the form of text as follows:

...

         S - Static value - it is read with the timeout which is defined by value of station protocol parameter Static Data Read Timeout.
           Group - number of GROUP, only one obligatory direct parameter
                 B - BCD coded number
                    Type - value type: 'F'-Float[4], 'c'-Char[1], 'L'-Long[4], 'U'-Ulong[4], 'i'-Int[2], 'u'-Uint[2]
                          .Offset - position in packet, implicitly at the beginning (0)
                                  .Bit - bitsbit number 1..8

The protocol supports data archive reading from the ELCOR-94 readingdata archive. It is possible to obtain the hour hourly records of the following values:

  • Momentary The current temperature (I/O with "OT" address),
  • Momentary The current pressure (I/O with "OP" address),
  • Operating volume (I/O with group "62" address),
  • Standardized volume (I/O with "NO" address).
